It may also be advantageous according to the invention to use pentosyl radicals.
It may likewise be advantageous to dispense with the abovementioned glycosidic radicals Gly 1-3 and to use the unsubstituted flavonoids (Gly 1-3 =H), such as, for example, quercitin. It may also be of advantage to use flavonoids in which the glucoside radical is bonded to C7, C4', C3' or C5' via phenolic OH functions.
It may moreover be of advantage to use flavonoids in which the phenolic OH function on C9 is present in the free form (so-called chalcones). It is particularly advantageous to use neohesperidin dihydrochalcone from this group.
The invention furthermore relates to compounds of flavonoids or flavone glycosides with derivatives of the abovementioned sugar radicals, such as 1→2; 1→3; 1→4 or 1→5 di-, oligo- or poly-alpha- or -betaglycosidic compounds of the same or different sugars with one another and sugar acids, as well as sugar esters, and also substituted sugars, for example with NR1R2, wherein R1 can be H or alkyl and R2 can be H or alkyl (for example N-acetylglucosamine).

It has furthermore proved to be advantageous in the prophylaxis and treatment of the dermatoses and hyperreactive and/or hypoactive deficiency states of the skin mentioned according to the invention under I. to XIII. to combine the active compounds according to the invention, and in particular the active compound systems 1-15, with urea and/or arginine (for example 0.01-15% by weight). The use of urea in cosmetic and dermatological formulations for treatment, in particular of dry states of the skin, is general prior art.
The term hypoactive states of the skin is to be understood according to the invention as meaning degenerative states of the skin which result in hypofunctioning of the skin and the integumentary appendages. This hypofunctioning can have its causes at the molecular level and be intra- or extracellular, such as, for example, hypofunctioning of the glutathione redox system, of catalase, of superoxide dismutase or of pyruvate carboxylase. As a consequence, the intra- and extracellular antioxidant status or energy metabolism status of individual cells, for example of the fibroblasts in the dermis or of the keratinocytes and Langerhans' cells in the epidermis, or even of the entire skin would be hypoactive.
The term hyperactive states of the skin is to be understood according to the invention as meaning states of the skin in which hyperexpression beyond the normal level, for example of individual metabolic routes or enzyme activities, such as, for example, phosphodiesterase activity, monoamine oxygenase activity or transaminase activity, is present. As a consequence, hyperproliferation, for example of the keratinocytes, or hyperactivity of Langerhans' cells or T-lymphocytes can be found.
The manifest dermatitis mentioned according to the invention means the dermatitis mentioned under I. to XIII. and their manifestations and synonyms.
It has also proved to be advantageous to use the active compounds and active compound combinations A) to E) for prophylaxis and treatment of the dermatitis mentioned according to the invention under I. to XIII. and for the hypo- and hyperactive states of the skin.

These individual components and the concentrations thereof in a formulation are mentioned by way of example without thereby excluding the use of other antioxidants and active compounds.
In the above combinations A to G, the % by weight data stated are in each case based on the total weight of the formulations or, for example, of the formulations of the examples. These combinations A to G are used in the examples.
For prophylaxis, the active compounds are administered to reduce the frequency and severity of manifestations of the diseases. Treatment in the manifest stage leads to a shortening thereof and to an alleviation of the symptoms.
Treatment with the active compounds according to the invention also serves to prevent or alleviate side effects and secondary damage which may occur when conventional treatment forms are used, such as, for example, UV treatment of psoriasis forms (PUVA treatment) and of atopic eczema and photodermatoses.
The active systems according to the invention, as an accompanying treatment form, furthermore allow a reduction in the dosage of conventional pharmacological active compounds, such as, for example, corticoids, for inflammatory dermatoses.
It is furthermore advantageous also to use the active compounds and formulations according to the invention in combination with conventional active compounds and methods usually used for treatment of the dermatoses mentioned (for example cyclosporin A, corticosteroids, psoralen, UV treatment, PUVA treatment, UVA and/or UVB filters, urea, antibiotics and aciclovir).
The active compounds according to the invention and combinations thereof and the formulations obtained with them, such as pharmaceutical preparations and topical formulations in the form of creams, lotions, gels and sprays, as well as solutions (for example aqueous, alcoholic or aqueous-alcoholic) and other suitable formulations are prophylactically active, in particular, in that they protect sensitive skin predisposed to the dermatoses mentioned under I. to XIII., in particular in the case of atopic dermatitis and photodermatoses, or reduce the development of these. For this, the formulations comprising the active compounds are used regularly once and several times daily. In the case of the manifest dermatoses mentioned, in particular atopic dermatitis (for example atopic eczema or neurodermatitis), ichthyosis, polymorphic photodermatosis, psoriasis and pruritus, an improvement in the state of the skin, in particular a subsidence in the itching which occurs with these dermatoses, takes place after adequate treatment with the active compounds and formulations according to the invention. The diseases can then be further treated prophylactically.
It was surprising and also not to be foreseen by the expert that the active compounds and formulations according to the invention can be used, in particular after topical application to human skin, for prophylaxis and treatment of the dermatoses mentioned under I. to XIII. and of sensitive, hyperreactive skin predisposed to dermatitis, and the combinations according to the invention of flavone glycosides and cinnamic acid derivatives and/or with antioxidant systems and/or active compounds which regulate endogenous energy metabolism, in particular in the skin, and/or antimicrobial active principles can achieve a synergistic action.
The action mechanism of the new active compounds and formulations according to the invention has not yet been clarified completely. It is assumed that an increased, oxidative, free-radical stress exists as the cause of the deficiency or pathological states of the skin in question, this being alleviated or even regulated to the normal level of intact and healthy skin by treatment with the active compounds according to the invention. It is also advantageous that the active compounds employed according to the invention also assist the enzymatic antioxidant and repair systems and the endogenous energy metabolism of the skin, so that an additive or even synergistic action mechanism exists in the active systems and formulations used according to the invention. These active compounds can arise at the site of action on the surface of the skin, mucous membrane and/or integumentary appendages, or by penetration via the sebaceous and sweat glands, and also along hair shafts or through the stratum corneum. For this, on the one hand certain active compounds according to the invention (for example antimicrobial active compounds) can be prevented from penetration into the skin in the formulations according to the invention, for example by coupling to specific carriers, so that only a superficial action is achieved on the skin and/or the hair and/or in the sebaceous and/or sweat glands and/or the hair shafts. To improve the penetration of certain active compounds into the skin, on the other hand, penetration promoters, such as, for example, dimethyl sulphoxide, azones, unsaturated fatty acids (for example oleic acid or cis-alkene fatty acids), heptadecanoic acid, liposomes, nanosomes, microsomes, niosomes and other encapsulation forms, can be added, or the active compounds can be packaged in these in order to achieve a sustained release and/or preserving effect.
Antimicrobial and/or antiviral active principles in combination with the antioxidant systems according to the invention and/or the systems which regulate endogenous energy metabolism can furthermore be used, in particular, for prophylaxis and treatment of dermatitis, such as, for example, neurodermatitis, atopic eczema, seborrhoeic eczema, rosacea, ichthyosis, and acne and psoriasis forms, and of viral infections, such as, for example, herpes simplex, h. labialis and h. zoster.
Such active systems or formulations should furthermore comprise active compounds which can be used for immunohomeostasis of diseased skin, and advantageously here also for immunostimulation in the sense of the action which promotes wound healing, especially with decubitus and ulcus cruris.
The active compounds according to the invention are particularly advantageously chosen from the group consisting of flavonoids and their glucosides, from the group consisting of cinnamic acid derivatives, in particular from the group consisting of ferulic acid derivatives and caffeic acid derivatives, and from the group consisting of antioxidants, in particular the group consisting of tocopherols and their derivatives and imidazoles and derivatives thereof.
Japanese Laid-Open Specification Hei-06-138,941 indeed describes oral formulations having a content of water-soluble glucosides, which can be chosen, for example, from the group consisting of α-glucosylrutin, α-glucosylmyrictrin, α-glucosylisoquercitrin and α-glucosylquercitrin. Japanese Laid-Open Specification Hei-04-363,395 describes a process for preventing decomposition of perfume constituents which is distinguished, inter alia, by an addition of α-glucosylrutin to the corresponding formulations. European Laid-Open Specification 586 303 and European Laid-Open Specification 595 694 furthermore describe the use of flavonoids as antioxidants or light protection substances in cosmetics. It is furthermore known from U.S. Pat. Nos. 4,144,325 and 4,248,861 and from numerous other documents to employ vitamin E in cosmetic and dermatological light protection formulations. The use according to the invention of vitamin E and its derivatives in the combinations according to the invention for cosmetic or dermatological prophylaxis and/or treatment of the dermatoses mentioned and of hyper- and hypoactive states of the skin, however, was not made obvious by the prior art.
No indication which could lead in the direction of the present direction is to be found in these specifications.
If vitamin E and/or derivatives thereof are the antioxidant or antioxidants, it is advantageous to choose the particular concentrations thereof from the range from 0.001 to 10% by weight, based on the total weight of the formulation.
The cosmetic and/or dermatological formulations according to the invention can have the customary composition and can be used for prophylaxis and/or treatment of the skin in the context of dermatological treatment or prophylaxis and/or treatment in the context of cosmetics. They preferably comprise 0.01% by weight to 20% by weight, but in particular 0.1% by weight to 6% by weight, based on the total weight, of one or more active compounds according to the invention.
It is advantageous according to the invention to use combinations of several of the active compounds according to the invention, especially if at least one of the components chosen from the group consisting of flavonoids or glucosides thereof and cinnamic acid derivatives is selected.
It is particularly advantageous to use combinations of flavonoids or derivatives thereof, cinnamic acid and its derivatives and antioxidants, in particular vitamin E and its derivatives.
For the preferred use, the active systems or formulations according to the invention comprising such active compounds, preferably combinations of flavonoids or derivatives thereof, cinnamic acid and derivatives thereof and antioxidants, in particular vitamin E and derivatives thereof, in combination with energy metabolism metabolites and/or antimicrobial active systems, are applied to the skin in an adequate amount in the manner customary for cosmetics or dermatological agents.
The cosmetic and dermatological formulations according to the invention can be in various forms. They can thus be, for example, a solution, an emulsion of the water-in-oil (w/o) type or of the oil-in-water (o/w) type, or a multiple emulsion, for example of the water-in-oil-in-water (w/o/w) or oil-in-water-in-oil (o/w/o) type, a gel, a solid stick or also an aerosol. They are prepared in a manner known per se.
The cosmetic and dermatological formulations according to the invention can comprise cosmetic and dermatological auxiliaries such as are usually used in such formulations, for example UV/A and UV/B filters, preservatives, bactericides, perfumes, agents for preventing foaming, dyestuffs, pigments which have a colouring action, thickeners, surface-active substances, emulsifiers, softening substances, humidifying and/or humectant substances, fats, oils, waxes or other customary constituents of a cosmetic formulation, such as alcohols, polyols, polymers, foam stabilizers, electrolytes, organic solvents or silicone derivatives.
It is also advantageous to administer the active compound combinations according to the invention in encapsulated form, for example encapsulated in collagen matrices and other customary encapsulating materials, for example as cellulose encapsulations, in gelatin or wax matrices or liposomally. Wax matrices such as are described in DE-A- 43 08 282 have proved to be particularly favourable.
If the cosmetic or dermatological formulation is a solution or lotion, solvents which can be used are:
water or aqueous solutions;
oils, such as triglycerides of capric or of caprylic acid, or liquid triglycerides of natural origin;

Suitable propellants for cosmetic or dermatological formulations according to the invention which can be sprayed from aerosol containers are the customary known readily volatile, liquefied propellants, for example hydrocarbons (propane, butane, isobutane), which can be employed by themselves or as a mixture with one another. Compressed air can also advantageously be used.
The expert of course knows that there are propellent gases which are non-toxic per se which would be suitable in principle for the present invention, but which should nevertheless be omitted because of an unacceptable action on the environment or other concommitant circumstances, in particular fluorohydrocarbons and fluorochlorohydrocarbons (CFCs).
The formulations according to the invention can furthermore preferably comprise substances which absorb UV radiation in the UVB range, the total amount of filter substances being, for example, 0.1% by weight to 30% by weight, preferably 0.5 to 10% by weight, in particular 1 to 6% by weight, based on the total weight of the formulation, in order to provide cosmetic formulations which protect the skin from the entire range of ultraviolet radiation. They can also be used as sunscreen agents.
The UVB filters can be oil-soluble or water-soluble. Oil-soluble substances which may be mentioned are, for example:
3-benzylidenecamphor derivatives, preferably 3-(4-methylbenzylidene)camphor and 3-benzylidenecamphor;
4-aminobenzoic acid derivatives, preferably 2-ethylhexyl 4-(dimethylamino)-benzoate and amyl 4-(dimethylamino)benzoate;

The list of UVB filters mentioned, which can be used in combination with the free radical scavengers according to the invention, is of course not intended to be limiting.
The invention also relates to the combination of one or more active compounds according to the invention with one or more UVB filters, and cosmetic or dermatological formulations according to the invention which also comprise one or more UVB filters.
It may also be advantageous to combine one or more active compounds according to the invention with UVA filters which have usually been contained to date in cosmetic and/or dermatological formulations. These substances are preferably derivatives of dibenzoylmethane, in particular 1-(4'-tert-butylphenyl)-3-(4'-methoxyphenyl)propane-1,3-dione and 1-phenyl-3-(4'-isopropylphenyl)propane-1,3-dione. The invention also relates to these combinations and formulations which comprise these combinations. The amounts used for the UVB combination can be employed.
Advantageous formulations are furthermore obtained if the active compounds according to the invention are combined with UVA and UVB filters.
Cosmetic formulations comprising free radical collectors according to the invention can also comprise inorganic pigments which are usually used in cosmetics for protecting the skin from UV rays. These are oxides of titanium, zinc, iron, zirconium, silicon, manganese, aluminium and cerium and mixtures thereof, as well as modifications in which the oxides are the active agents. The pigments are particularly preferably those based on titanium dioxide.
The invention also relates to these combinations of UVA filters and/or UVB filters and pigment and to formulations which comprise this combination. The amounts mentioned for the above combinations can be used.
The use of active compound combinations according to the invention for protection of the skin and/or hair against exposure to oxidation, in particular this use of the active compound combinations according to the invention in shampoos and washing formulations, is therefore also regarded as an advantageous embodiment of the present invention. Cosmetic formulations which are a skin cleansing composition or shampooing composition preferably comprise at least one anionic, nonionic or amphoteric surface-active substance or also mixtures of such substances, active compounds according to the invention and auxiliaries such as are usually used for this purpose. The surface-active substance or the mixtures of these substances can be present in the shampooing composition in a concentration of between 1% by weight and 50% by weight.
If the cosmetic or dermatological formulations are in the form of a lotion which is rinsed out and is used, for example, before or after bleaching, before or after shampooing, between two shampooing steps or before or after permanent wave treatment, they are, for example, aqueous or aqueous-alcoholic solutions which comprise, if appropriate, surface-active substances, preferably nonionic or cationic surface-active substances, the concentration of which can be between 0.1 and 10% by weight, preferably between 0.2 and 5% by weight. These cosmetic or dermatological formulations can also be aerosols with the auxiliaries usually used for this purpose.
Formulations for treatment of the scalp and hair can be in the form of emulsions which are of the nonionic or anionic type. Nonionic emulsions comprise, in addition to water, oils or fatty alcohols, which can also be polyethoxylated or polypropoxylated, for example, or also mixtures of the two organic components. If appropriate, these emulsions comprise cationic surface-active substances.
According to the invention, cosmetic formulations for treatment of the skin, scalp and hair can be in the form of gels or hair lotions which comprise, in addition to an active content of active compounds according to the invention and solvents usually used for this purpose, preferably water, also organic thickeners, for example gum arabic, xanthan gum, sodium alginate, cellulose derivatives, preferably methylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose or hydroxypropylmethylcellulose, or inorganic thickeners, for example aluminium silicates, such as, for example, bentonites, or a mixture of polyethylene glycol and polyethylene glycol stearate or distearate. The gel comprises the thickener, for example, in an amount of between 0.1 and 30% by weight, preferably between 0.5 and 15% by weight.
Unless stated otherwise, all the amounts data, contents and percentage contents are based on the weight and the total weight or on the total weight of the formulations.
Pharmaceutical preparations, agents or compositions which comprise the compounds according to the invention or derivatives or pharmaceutically tolerated salts thereof together with a pharmaceutically tolerated diluent or carrier are also provided according to the invention as formulations.
The compounds of the present invention can be used on humans orally or parenterally, for example in a dosage of 0.01 to 5000 mg, preferably 1 to 500 mg per day, in particular also in subdivided doses, for example twice to four times daily.
The active compounds according to the invention can be mixed with customary pharmaceutically tolerated diluents or carriers and, if appropriate, with other auxiliaries, and can be administered, for example, orally or parenterally. They can preferably be administered orally in the form of granules, capsules, pills, tablets, film-coated tablets, sugar-coated tablets, syrups, emulsions, suspensions, dispersions, aerosols and solutions and liquids, or else as suppositories or vaginal beads, or parenterally, for example in the form of solutions, emulsions or suspensions. Preparations to be administered orally can comprise one or more additives, such as sweeteners, flavourings, dyestuffs and preservatives. Tablets can comprise the active compound mixed with customary pharmaceutically tolerated auxiliaries, for example inert diluents, such as calcium carbonate, sodium carbonate, lactose and talc, granulating agents and agents which promote disintegration of the tablets on oral administration, such as starch or alginic acid, binders, such as starch or gelatin, and lubricants, such as magnesium stearate, stearic acid and talc.
Suitable carriers are, for example, milk sugar (lactose), gelatin, maize starch, stearic acid, ethanol, propylene glycol, ethers of tetrahydrofurfuryl alcohol and water.
The formulations are prepared, for example, by extending the active compounds with solvents and/or carriers, if appropriate using emulsifying agents and/or dispersing agents, it being possible, for example in the case where water is used as a diluent, for organic solvents to be used as auxiliary solvents if appropriate.
Administration is effected in the customary manner, preferably orally or parenterally, in particular perlingually or intravenously. In the case of oral use, tablets can of course also contain, in addition to the carriers mentioned, additives, such as sodium citrate, calcium carbonate and dicalcium phosphate, together with various additives, such as starch, preferably potato starch, gelatin and the like. Lubricants, such as magnesium stearate, sodium lauryl sulphate and talc, can furthermore be co-used for tablet-making. In the case of aqueous suspensions and/or elixirs intended for oral uses, various flavour improvers or dyestuffs, in addition to the abovementioned auxiliaries, can be added to the active compounds.
In the case of parenteral use, solutions of active compounds can be employed, using suitable liquid carrier materials.
Capsules can comprise the active compound as the sole constituent or as a mixture with a solid diluent, such as calcium carbonate, calcium phosphate or kaolin. The injectable preparations are likewise formulated in a manner known per se.
The pharmaceutical preparations can comprise the active compound in an amount of 0.1 to 90% by weight, in particular 1-90% by weight. Capsules are particularly preferred. Individual doses preferably comprise the active compounds in an amount of 0.01 mg-500 mg.
The invention also relates to pharmaceutical and topical formulations, which are characterized in that they comprise a combination of antioxidants and regulating active compounds according to the invention, and the combination of antioxidants and/or regulating active compounds according to the invention with antiviral and/or antimicrobial active principles as described above.
Unless stated otherwise, all the amounts data, contents and percentage contents are based on the weight and the total amount or on the total weight of the formulations.
In the examples, the combinations A-G of individual substances mentioned are used with the parts by weight stated, which in each case represent the weight ratios of the individual substances in the formulation.

(en)DESCRIPTION
Agents against hyperreactive and hypoactive, deficiency states of the skin and manifest dermatitis.
The present invention particularly relates to active compounds and formulations, in particular for topical use, which are used for prophylaxis and treatment of hyperreactive skin predisposed to dermatitis, and of deficient hypoactive skin and for prophylaxis and treatment of the manifest dermatoses mentioned under I. to XIII., such as, for example, atopic dermatitis, neurodermatitis, atopic eczema and seborrhoeic dermatitis, photoinduced dermatoses (for example Mallorca acne and in particular polymorphic photodermatosis and photodermatitis), rosacea, prurigo forms, pruritus, psoriasis forms, ichthyosis, decubitus, ulcus cruris and microbial and viral infections, such as, for example, herpes simplex, h.zoster or h.labialis.
The skin states according to the invention are explained below in more detail.
Various pathological mechanisms which characterize the clinical picture of hypoactive skin or hyperreactive skin and the dermatoses mentioned under I. to XIII., such as, for example, forms of acne, atopic dermatitis, prurigo forms, psoriasis, photodermatoses, decubitus, ulcus cruris and ichthyosis, are described in the literature. However, the causal pathological mechanisms and the chronology thereof are not sufficiently known for any of the dermatoses mentioned. The treatment methods and active compounds administered which are known to date lead in the most favourable case to a brief improvement in the symptoms. UV treatment and/or chemotherapy (psoralen, PUVA, cyclosporin A, corticosteroids, acyclovir and the like), for example, are used for treatment, with the known adverse side effects on repeated administration.
The object of the invention is to improve this unsatisfactory prior art and to provide cosmetic, dermatological and/or pharmaceutical active compounds and formulations which are used for prophylaxis and treatment of deficient, hypoactive skin or for prophylaxis and treatment of hyperreactive skin with a propensity to dermatitis, and for prophylaxis and treatment of the manifest dermatoses mentioned under sections I. to XIII. below, without inducing the side effects of known agents, even during long-term use.
These objects are achieved according to the invention.
The invention relates to the use of
a) a compound or several compounds from the group consisting of flavonoids, or
b) an active compound combination comprising a compound or several compounds chosen from the group consisting of flavonoids, in combination with a compound or several compounds chosen from the group consisting of cinnamic acid derivatives, and if appropriate additionally in each case a compound or several compounds from one of the groups or several of the groups
c) of the antioxidants or
d) of the endogenous energy metabolism metabolites or

It has furthermore proved to be advantageous in the prophylaxis and treatment of the dermatoses and hyperreactive and/or hypoactive deficiency states of the skin mentioned according to the invention under I. to XIII. to combine the active compounds according to the invention, and in particular the active compound systems 1-15, with urea and/or arginine (for example 0.01-15% by weight). The use of urea in cosmetic and dermatological formulations for treatment, in particular of dry states of the skin, is general prior art.
The term hypoactive states of the skin is to be understood according to the invention as meaning degenerative states of the skin which result in hypofunctioning of the skin and the integumentary appendages. This hypofunctioning can have its causes at the molecular level and be intra- or extracellular, such as, for example, hypofunctioning of the glutathione redox system, of catalase, of superoxide dismutase or of pyruvate carboxylase. As a consequence, the intra- and extracellular antioxidant status or energy metabolism status of individual cells, for example of the fibroblasts in the dermis or of the keratinocytes and Langerhans' cells in the epidermis, or even of the entire skin would be hypoactive.
The term hyperactive states of the skin is to be understood according to the invention as meaning states of the skin in which hyperexpression beyond the normal level, for example of individual metabolic routes or enzyme activities, such as, for example, phosphodiesterase activity, monoamine oxygenase activity or transaminase activity, is present. As a consequence, hyperproliferation, for example of the keratinocytes, or hyperactivity of Langerhans' cells or T-lymphocytes can be found.
The manifest dermatitis mentioned according to the invention means the dermatitis mentioned under I. to XIII. and their manifestations and synonyms.
It has also proved to be advantageous to use the active compounds and active compound combinations A) to E) for prophylaxis and treatment of the dermatitis mentioned according to the invention under I. to XIII. and for the hypo- and hyperactive states of the skin.

Combinations of these active compounds with active systems 1 and 4-13 have also proved to be particularly advantageous for prophylaxis and treatment, in particular of chronic wounds.
These individual components and the concentrations thereof in a formulation are mentioned by way of example without thereby excluding the use of other antioxidants and active compounds.
In the above combinations A to G, the % by weight data stated are in each case based on the total weight of the formulations or, for example, of the formulations of the examples. These combinations A to G are used in the examples.
For prophylaxis, the active compounds are administered to reduce the frequency and severity of manifestations of the diseases. Treatment in the manifest stage leads to a shortening thereof and to an alleviation of the symptoms.
Treatment with the active compounds according to the invention also serves to prevent or alleviate side effects and secondary damage which may occur when conventional treatment forms are used, such as, for example, UV treatment of psoriasis forms (PUVA treatment) and of atopic eczema and photodermatoses.
The active systems according to the invention, as an accompanying treatment form, furthermore allow a reduction in the dosage of conventional pharmacological active compounds, such as, for example, corticoids, for inflammatory dermatoses.
It is furthermore advantageous also to use the active compounds and formulations according to the invention in combination with conventional active compounds and methods usually used for treatment of the dermatoses mentioned (for example cyclosporin A, corticosteroids, psoralen, UV treatment, PUVA treatment, UVA and/or UVB filters, urea, antibiotics and aciclovir).
The active compounds according to the invention and combinations thereof and the formulations obtained with them, such as pharmaceutical preparations and topical formulations in the form of creams, lotions, gels and sprays, as well as solutions (for example aqueous, alcoholic or aqueous-alcoholic) and other suitable formulations are prophylactically active, in particular, in that they protect sensitive skin predisposed to the dermatoses mentioned under I. to XIII., in particular in the case of atopic dermatitis and photodermatoses, or reduce the development of these. For this, the formulations comprising the active compounds are used regularly once and several times daily. In the case of the manifest dermatoses mentioned, in particular atopic dermatitis (for example atopic eczema or neurodermatitis), ichthyosis, polymorphic photodermatosis, psoriasis and pruritus, an improvement in the state of the skin, in particular a subsidence in the itching which occurs with these dermatoses, takes place after adequate treatment with the active compounds and formulations according to the invention. The diseases can then be further treated prophylactically.
It was surprising and also not to be foreseen by the expert that the active compounds and formulations according to the invention can be used, in particular after topical application to human skin, for prophylaxis and treatment of the dermatoses mentioned under I. to XIII. and of sensitive, hyperreactive skin predisposed to dermatitis, and the combinations according to the invention of flavone glycosides and cinnamic acid derivatives and/or with antioxidant systems and/or active compounds which regulate endogenous energy metabolism, in particular in the skin, and/or antimicrobial active principles can achieve a synergistic action.
The action mechanism of the new active compounds and formulations according to the invention has not yet been clarified completely. It is assumed that an increased, oxidative, free-radical stress exists as the cause of the deficiency or pathological states of the skin in question, this being alleviated or even regulated to the normal level of intact and healthy skin by treatment with the active compounds according to the invention. It is also advantageous that the active compounds employed according to the invention also assist the enzymatic antioxidant and repair systems and the endogenous energy metabolism of the skin, so that an additive or even synergistic action mechanism exists in the active systems and formulations used according to the invention. These active compounds can arise at the site of action on the surface of the skin, mucous membrane and/or integumentary appendages, or by penetration via the sebaceous and sweat glands, and also along hair shafts or through the stratum corneum. For this, on the one hand certain active compounds according to the invention (for example antimicrobial active compounds) can be prevented from penetration into the skin in the formulations according to the invention, for example by coupling to specific carriers, so that only a superficial action is achieved on the skin and/or the hair and/or in the sebaceous and/or sweat glands and/or the hair shafts. To improve the penetration of certain active compounds into the skin, on the other hand, penetration promoters, such as, for example, dimethyl sulphoxide, azones, unsaturated fatty acids (for example oleic acid or cis-alkene fatty acids), heptadecanoic acid, liposomes, nanosomes, microsomes, niosomes and other encapsulation forms, can be added, or the active compounds can be packaged in these in order to achieve a sustained release and/or preserving effect.
Antimicrobial and/or antiviral active principles in combination with the antioxidant systems according to the invention and/or the systems which regulate endogenous energy metabolism can furthermore be used, in particular, for prophylaxis and treatment of dermatitis, such as, for example, neurodermatitis, atopic eczema, seborrhoeic eczema, rosacea, ichthyosis, and acne and psoriasis forms, and of viral infections, such as, for example, herpes simplex, h. labialis and h. zoster.
Such active systems or formulations should furthermore comprise active compounds which can be used for immunohomeostasis of diseased skin, and advantageously here also for immunostimulation in the sense of the action which promotes wound healing, especially with decubitus and ulcus cruris.
The active compounds according to the invention are particularly advantageously chosen from the group consisting of flavonoids and their glucosides, from the group consisting of cinnamic acid derivatives, in particular from the group consisting of ferulic acid derivatives and caffeic acid derivatives, and from the group consisting of antioxidants, in particular the group consisting of tocopherols and their derivatives and imidazoles and derivatives thereof.
Japanese Laid-Open Specification Hei-06-138,941 indeed describes oral formulations having a content of water-soluble glucosides, which can be chosen, for example, from the group consisting of α-glucosylrutin, α-glucosylmyrictrin, α-glucosylisoquercitrin and α-glucosylquercitrin. Japanese Laid-Open Specification Hei-04-363,395 describes a process for preventing decomposition of perfume constituents which is distinguished, inter alia, by an addition of α-glucosylrutin to the corresponding formulations. European Laid-Open Specification 586 303 and European Laid-Open Specification 595 694 furthermore describe the use of flavonoids as antioxidants or light protection substances in cosmetics. It is furthermore known from U.S. Pat. Nos. 4,144,325 and 4,248,861 and from numerous other documents to employ vitamin E in cosmetic and dermatological light protection formulations. The use according to the invention of vitamin E and its derivatives in the combinations according to the invention for cosmetic or dermatological prophylaxis and/or treatment of the dermatoses mentioned and of hyper- and hypoactive states of the skin, however, was not made obvious by the prior art.
No indication which could lead in the direction of the present direction is to be found in these specifications.
If vitamin E and/or derivatives thereof are the antioxidant or antioxidants, it is advantageous to choose the particular concentrations thereof from the range from 0.001 to 10% by weight, based on the total weight of the formulation.
The cosmetic and/or dermatological formulations according to the invention can have the customary composition and can be used for prophylaxis and/or treatment of the skin in the context of dermatological treatment or prophylaxis and/or treatment in the context of cosmetics. They preferably comprise 0.01% by weight to 20% by weight, but in particular 0.1% by weight to 6% by weight, based on the total weight, of one or more active compounds according to the invention.
It is advantageous according to the invention to use combinations of several of the active compounds according to the invention, especially if at least one of the components chosen from the group consisting of flavonoids or glucosides thereof and cinnamic acid derivatives is selected.
It is particularly advantageous to use combinations of flavonoids or derivatives thereof, cinnamic acid and its derivatives and antioxidants, in particular vitamin E and its derivatives.
For the preferred use, the active systems or formulations according to the invention comprising such active compounds, preferably combinations of flavonoids or derivatives thereof, cinnamic acid and derivatives thereof and antioxidants, in particular vitamin E and derivatives thereof, in combination with energy metabolism metabolites and/or antimicrobial active systems, are applied to the skin in an adequate amount in the manner customary for cosmetics or dermatological agents.
The cosmetic and dermatological formulations according to the invention can be in various forms. They can thus be, for example, a solution, an emulsion of the water-in-oil (w/o) type or of the oil-in-water (o/w) type, or a multiple emulsion, for example of the water-in-oil-in-water (w/o/w) or oil-in-water-in-oil (o/w/o) type, a gel, a solid stick or also an aerosol. They are prepared in a manner known per se.
The cosmetic and dermatological formulations according to the invention can comprise cosmetic and dermatological auxiliaries such as are usually used in such formulations, for example UV/A and UV/B filters, preservatives, bactericides, perfumes, agents for preventing foaming, dyestuffs, pigments which have a colouring action, thickeners, surface-active substances, emulsifiers, softening substances, humidifying and/or humectant substances, fats, oils, waxes or other customary constituents of a cosmetic formulation, such as alcohols, polyols, polymers, foam stabilizers, electrolytes, organic solvents or silicone derivatives.
It is also advantageous to administer the active compound combinations according to the invention in encapsulated form, for example encapsulated in collagen matrices and other customary encapsulating materials, for example as cellulose encapsulations, in gelatin or wax matrices or liposomally. Wax matrices such as are described in DE-A- 43 08 282 have proved to be particularly favourable.
If the cosmetic or dermatological formulation is a solution or lotion, solvents which can be used are:
water or aqueous solutions;
oils, such as triglycerides of capric or of caprylic acid, or liquid triglycerides of natural origin;

Suitable propellants for cosmetic or dermatological formulations according to the invention which can be sprayed from aerosol containers are the customary known readily volatile, liquefied propellants, for example hydrocarbons (propane, butane, isobutane), which can be employed by themselves or as a mixture with one another. Compressed air can also advantageously be used.
The expert of course knows that there are propellent gases which are non-toxic per se which would be suitable in principle for the present invention, but which should nevertheless be omitted because of an unacceptable action on the environment or other concommitant circumstances, in particular fluorohydrocarbons and fluorochlorohydrocarbons (CFCs).
The formulations according to the invention can furthermore preferably comprise substances which absorb UV radiation in the UVB range, the total amount of filter substances being, for example, 0.1% by weight to 30% by weight, preferably 0.5 to 10% by weight, in particular 1 to 6% by weight, based on the total weight of the formulation, in order to provide cosmetic formulations which protect the skin from the entire range of ultraviolet radiation. They can also be used as sunscreen agents.
The UVB filters can be oil-soluble or water-soluble. Oil-soluble substances which may be mentioned are, for example:
3-benzylidenecamphor derivatives, preferably 3-(4-methylbenzylidene)camphor and 3-benzylidenecamphor;
4-aminobenzoic acid derivatives, preferably 2-ethylhexyl 4-(dimethylamino)-benzoate and amyl 4-(dimethylamino)benzoate;

The list of UVB filters mentioned, which can be used in combination with the free radical scavengers according to the invention, is of course not intended to be limiting.
The invention also relates to the combination of one or more active compounds according to the invention with one or more UVB filters, and cosmetic or dermatological formulations according to the invention which also comprise one or more UVB filters.
It may also be advantageous to combine one or more active compounds according to the invention with UVA filters which have usually been contained to date in cosmetic and/or dermatological formulations. These substances are preferably derivatives of dibenzoylmethane, in particular 1-(4'-tert-butylphenyl)-3-(4'-methoxyphenyl)propane-1,3-dione and 1-phenyl-3-(4'-isopropylphenyl)propane-1,3-dione. The invention also relates to these combinations and formulations which comprise these combinations. The amounts used for the UVB combination can be employed.
Advantageous formulations are furthermore obtained if the active compounds according to the invention are combined with UVA and UVB filters.
Cosmetic formulations comprising free radical collectors according to the invention can also comprise inorganic pigments which are usually used in cosmetics for protecting the skin from UV rays. These are oxides of titanium, zinc, iron, zirconium, silicon, manganese, aluminium and cerium and mixtures thereof, as well as modifications in which the oxides are the active agents. The pigments are particularly preferably those based on titanium dioxide.
The invention also relates to these combinations of UVA filters and/or UVB filters and pigment and to formulations which comprise this combination. The amounts mentioned for the above combinations can be used.
The use of active compound combinations according to the invention for protection of the skin and/or hair against exposure to oxidation, in particular this use of the active compound combinations according to the invention in shampoos and washing formulations, is therefore also regarded as an advantageous embodiment of the present invention. Cosmetic formulations which are a skin cleansing composition or shampooing composition preferably comprise at least one anionic, nonionic or amphoteric surface-active substance or also mixtures of such substances, active compounds according to the invention and auxiliaries such as are usually used for this purpose. The surface-active substance or the mixtures of these substances can be present in the shampooing composition in a concentration of between 1% by weight and 50% by weight.
If the cosmetic or dermatological formulations are in the form of a lotion which is rinsed out and is used, for example, before or after bleaching, before or after shampooing, between two shampooing steps or before or after permanent wave treatment, they are, for example, aqueous or aqueous-alcoholic solutions which comprise, if appropriate, surface-active substances, preferably nonionic or cationic surface-active substances, the concentration of which can be between 0.1 and 10% by weight, preferably between 0.2 and 5% by weight. These cosmetic or dermatological formulations can also be aerosols with the auxiliaries usually used for this purpose.
