Despite the colours achieved are relatively stable and long lasting, unsatisfactory results have especially been observed with colouring and colour stability on damage hair. Problem is especially big when hair includes parts with various levels of damage. This is especially the case when hair is chemical treated in various ways such as oxidative colouring, bleaching which is at the same time an oxidative treatment in a larger extent and permanent shaping treatments which include reducing and oxidation steps.

The Part A and B were mixed at a weight ratio of 1:1 and applied onto hair immediately afterwards and after processing of 30 min rinsed off from hair and hair was washed once with a commercially available shampoo and dried with a hair dryer.
It was observed that hair was intensively, homogeneously coloured and homogeneously conditioned from root to tip.
For comparative purposes, cationic polymer was excluded from the Part B which was resulted in less conditioning of hair and especially uncared damaged tips were observed. Additionally, hair was somewhat less homogeneously coloured.
Similar results were obtained with the examples below.

The present invention relates to a two part aqueous oxidative colouring composition for keratin fibres especially human hair with improved and homogeneous conditioning effect from root to tip, improved colour fastness against washing and for achieving homogeneous even colouration.
Oxidative hair colouring has been commonly used for many years. Despite the colours achieved are relatively stable and long lasting, unsatisfactory results have especially been observed with colouring and colour stability on damage hair. Problem is especially big when hair includes parts with various levels of damage. This is especially the case when hair is chemical treated in various ways such as oxidative colouring, bleaching which is at the same time an oxidative treatment in a larger extent and permanent shaping treatments which include reducing and oxidation steps.

The UV-absorbing substance is preferably selected from the following compounds: 4-Aminobenzoic acid and the esters and salts thereof, 2-phenyl benzimidazole-5-sulfonic acid and the alkali and amine salts thereof, 4-dimethyl aminobenzoic acid and the esters and salts thereof, cinnamic acid and the esters and salts thereof, 4-methoxycinnamic acid and the esters and salts thereof, salicylic acid and the esters and salts thereof, 2,4-dihydroxybenzophenone, 2,2′,4,4′-tetrahydroxy-benzophenone, 2-hydroxy-4-methoxybenzophenone and its 5-sulfonic acid or the sodium salt thereof, 2,2′-dihydroxy-4,4′-dimethoxybenzophenone, 2-hydroxy-5-chlorobenzophenone, 2,2′-dihydroxy-4-methoxybenzophenone, 2,2′-dihydroxy-4,4′-dimethoxy-5,5′-disulfobenzo-phenone or the sodium salt thereof, 2-hydroxy-4-octyloxybenzophenone, 2-hydroxy-4-methoxy-4′-methylbenzophenone, 3-benzyl-idenecampher, 3-(4′-sulfo)-benzyl-idenebornane-2-one and the salts thereof and/or 3-(4′-methyl benzylidene)-DL-campher, polysilicone-15. The preferred amount of the UV-absorber ranges from about 0.01% to 2.5%, more preferably from 0.05% to 1% by weight, calculated to the total composition.
The compositions of the present invention can comprise one or more hair-restructuring agents. The hair restructuring agents preferred are especially the ones disclosed in the German patent DE 197 51 550 C2. Namely they are ceramide type of compounds, fatty acids and phytosterol or their mixtures.
Preferred ceramide compound is cetyl-PG-hydroxyethylpalmitamide.
Preferred fatty acids are as mentioned above.
Sterols, specially the phytosterols, are as well preferred hair restructuring agents as disclosed in the above mentioned german patent. Especially preferred ones are of plant origin for example ergosterol, sitosterol, stigmasterol, fucosterol, brassicasterol, fungisterol, campesterol, zymosterol, ascosterol, cerevisterol, episterol, faecosterol, spinasterol. Among those phytosterols, the ones found in “Avocadin” which is the unsaponified fraction of the avocado oil is more preferred.
The concentration of ceramide in the compositions of the present invention can be in the range of 0.01 to 2% and especially 0.01 to 1% by weight calculated to the total weight of the composition. Phytosterol concentration of the conditioners is less than 1% and preferably in the range of 0.01 to 0.5% by weight calculated to the total weight of the composition. It should be noted without limiting the use of those ingredients the effect of those hair restructuring ingredients is especially elevated when used in combination with penetration enhancers.
One or both parts of the compositions of the present invention may comprise further at least one compound according to the formula
where n is a number from 1 to 10.
The compounds of the above formula are known as Ubiquinone, and also are known as Coenzyme. It should be noted that the compositions of the present invention can certainly comprise more than one ubichinone. Preferred ubichinones are the ones where n is a number between 6 and 10 and especially preferred is Ubichinone 50 where n is 10, also known as Coenzyme Q10. Concentration ubichinone of the above formula in the compositions is from 0.00001 to 1%, preferably from 0.0001 to 0.75%, more preferably from 0.0001 to 0.5% and most preferably from 0.0002 to 0.5% by weight, calculated to total composition.
Compositions of the present invention may further comprise particulate matter such as synthetic mica. Use of synthetic mica coated with metal oxide or oxides mainly in decorative cosmetics is disclosed in an international patent application of Sun Chemical Corporation published with a number WO 2005/065632 A1. In the document synthetic mica and coated synthetic mica with at least one metal oxide or oxides is disclosed in detail, the content of the document is included herewith by reference.
Suitable metal oxide or oxides for coating synthetic mica are titanium dioxide, chromium oxide, ferric oxide or mixtures thereof. In the present invention the preferred is synthetic mica coated with titanium dioxide. Such materials are commercially available from Sun Chemical Corporation and are known with their INCI names Synthetic Fluorphologopite.
The particle size distribution of synthetic mica coated with a metal oxide or oxides is in the range of 1 to 750 μm, preferably 1 to 250 μm, more preferably 1 to 100 μm and most preferably 20 to 95 μm. The particle sizes referred are relating to the volume particle size distribution meaning that particles found in the coated synthetic mica having volume particle size in the given ranges.
Concentration of synthetic mica coated with at least metal oxide or oxides is from 0.001 to 10%, preferably 0.05 to 7.5%, more preferably 0.1 to 5% and most preferably 0.25 to 2.5% by weight calculated to total composition.
The pH of the Part A and after mixing both parts according to the invention is in the range of 2 to 11 preferably 5 to 11, more preferably 6 to 11, most preferably 6.8 to 11. pH of part B prior to mixing with Part A is in the range of 1 to 6, preferably 2 to 5 and more preferably 1.8 to 4.5. pH of the compositions can be adjusted by using any organic and/or inorganic acids and alkalizing agents such as ammonium hydroxide and monoethanolamine or their mixtures.
Furthermore, compositions of the present invention can comprise all substances customarily found in such preparations. Examples of such substances are complexing agents, preservatives, fragrances, and antioxidants such as sodium sulfit.

The Part A and B were mixed at a weight ratio of 1:1 and applied onto hair immediately afterwards and after processing of 30 min rinsed off from hair and hair was washed once with a commercially available shampoo and dried with a hair dryer.
It was observed that hair was intensively, homogeneously coloured and homogeneously conditioned from root to tip.
For comparative purposes, cationic polymer was excluded from the Part B which was resulted in less conditioning of hair and especially uncared damaged tips were observed. Additionally, hair was somewhat less homogeneously coloured.
Similar results were obtained with the examples below.
