FIELD OF THE INVENTION
This invention relates to an alternating copolymer of organopolysiloxane with glycerol derivative and to a cosmetic comprising the same as an oil agent or an emulsifier.
DESCRIPTION OF THE PRIOR ART
Human secretions such as sweat, tears and sebum cause makeup runs. Especially, in makeup cosmetics, an oil agent contained in cosmetics along with sebum secreted from the skin causes excessive wetting of cosmetic powder, which results in serious makeup runs. In order to reduce the amount of cosmetic oil remaining on the skin, an attempt was made to use a volatile oil such as octamethylcyclotetrasiloxane or decamethylcyclopentasiloxane as a part of the oil ingredients to be added.
Generally, an oily cosmetic has good affinity to skin and durability, but it tends to give a user uncomfortable feeling such as oily, tacky, heavy or thick feeling. To reduce the oiliness, use has been made of a silicone oil which extends well on the skin and gives refreshed feeling. By incorporating the silicone oil, the oiliness is indeed reduced. However, negative properties of the silicone oil such as poor affinity and lack of moisturizing function prevail and the good affinity of an oily cosmetic is lost, too. In addition, satisfactory shiny finish was not obtained.
Although polysiloxanes have good properties as oily agents used for cosmetics, properties concerning feeling are not satisfactory such as affinity with skin, moisturized feeling and dryness.
In makeup cosmetics such as foundation, water repellency has not been improved enough. In skin-care cosmetics such as a milky lotion, an oily agent is desired which has a light feeling, good water repellency, good usability and affinity to the skin.
Meanwhile, a silicone oil obtained by modifying a dimethylpolysiloxane with fluoroalkyl groups described in Japanese Patent Application (JPA) Laid-Open No. 2-295912 has a higher oil repellency than dimethylpolysiloxane.
As the content of the floroalkyl groups increases, the oil repellency increases, but a heavier feeling to the skin occurs. Further, solubility in octamethylcyclotetrasiloxane or decamethylcyclopentasiloxane decreases, which is inconvenient in preparing cosmetic. To get enough solubility, the floroalkyl groups should be decrease, which in turn decrease the oil repellency and the affinity to the skin.
Recently, in a water-in-oil type emulsion (w/o emulsion) composition, a silicone oil is used. Such a w/o emulsion containing the silicone oil is difficult to obtain by using a conventionally used emulsifier such as polyoxyalkylene fatty acid ester.
As a surfactant for the aforesaid w/o emulsion, use of a polyoxyalkylene-modified organopolysiloxane, i.e., polyether-modified silicone which has a good compatibility with a silicone oil is proposed in JPA Laid-Open No. 61-293903, JPA Laid-Open No. 61-293904, JPA Laid-Open No. 62-187406, JPA Laid-Open No. 62-215510, and JPA Laid-Open No. 62-216635.
To prepare an emulsion for a cosmetic application, an ester oil and a hydrocarbon oil are often used together with a silicone oil as a mixture. With the aforesaid polyether-modified silicone, an emulsion of such a mixed oil system is difficult to prepare due to a lack of emulsifying capability of the polyether-modified silicone.
To solve this problem, it is proposed in JPA Laid-Open No. 61-90732 to use the following organopolysiloxane as an emulsifier which has a long alkyl chain and a polyoxyalkylene group.


The above organopolysiloxane compound is a good emulsifier for a mixed oil system containing relatively large amount of ester oil or hydrocarbon oil, but not good enough to prepare a stable emulsion of a system containing relatively large amount of silicone oil.
As shown in the formula (5), in an organopolysiloxane compound having a polyoxyalkylene group, the polyoxyalkylene group is usually grafted to the organopolysiloxane chain. Other type of organopolysiloxane is known which has a polyoxyalkylene group (A) bonded to one or both terminals of a siloxane residue (B) to form (AB) type or (ABA) type organopolysiloxane. In Japanese Patents No. 3061434, No. 3071222, and No. 3283277, an organopolysiloxane having a repeating unit of (AB) is disclosed. It is described that the organopolysiloxane functions as an antistatic agent, which is attributed to the polyalkylene group, and can be used for skin cosmetics as well as hair cosmetics.
In an application of a skin cleaning agent, cleaning of makeup cosmetics containing large amount of solid oil such as a lipstick, foundation, eye shadow, eyeliner, and mascara is an issue. A cleaning agent comprising an ordinary soap cannot clean these cosmetic completely, because the soap cannot (dissolve or emulsify the solid oil.
To clean such oily cosmetics, a cleaning agent mainly composed of an oily material has been used. However, such cleaning agent is not enough to clean a makeup cosmetic designed to give a durable and long lasting makeup or the one containing cyclic silicones or a film forming polymer intended to be used in summer when people sweat a lot. In a hair cosmetic, a highly polymerized silicone or a polymer having a high film forming capability is used to protect hair, to add hair bounce or smooth feeling.
To clean such a durable makeup or film forming polymer on hair, a cleaning agent containing a nonionic surfactant or a polyethe-modified silicone is used. However, as film forming capability increases, a cleaning agent having a higher cleaning capability is desired.
Meanwhile, various kinds of glycerol-modified silicones have been reported to solve poor moisturization property and affinity to the skin.
For example, glycerol-modified silicones are described in JPA Laid-Open No. 6-157236, JPA Laid-Open No. 9-71504 and JP Kokoku No. 62-34039; glycerol- and fluoroalkyl-modified silicones in JPA Laid-Open No. 10-310504, No. 10-310505, No. 10-310506, No. 10-310507, No. 10-310508, and No. 10-310509; monoglycerol-modified silicones and a cosmetic comprising the same in Japanese Patent Publication (JP) No. 2613124, JP No. 2844453, JP Kokoku No. 8-22811, JP No. 2587797, and JP No. 2601738. All of the glycerol-modified silicones are intended to suppress drying property of the silicone and tackiness of glycerol.
As a silicone modified with a compound having hydroxyl groups, a polyalcohol-modified silicone is also known wherein the polyalcohol is sucrose or polysacharide. In JP No. 3172787, a modified silicone having a sucrose residue is described and its application as an emulsifier is described in JP No. 3229396, JPA Laid-Open No. 7-41414, and Laid-Open No. 7-41416.
All of the modified silicones are intended to suppress drying property of the silicone with the polyalcohol including glycerol and to suppress tackiness of glycerol with the silicone.
The aforesaid known glycerol-modified silicones are superior to a conventional polyether-modified silicone in that they do not get viscous or show tackiness when mixed with water. However, one drawback with the glycerol-modified silicones is an availability of a raw material polyglycerol having reactive functional groups such as an aliphatic unsaturated group to be reacted with a silicone. For example, in preparing a glycerol-modified silicone by reacting the glycerol derivative compound represented by the formula below with an SiH bond of a silicone, miscibility of the compound with the silicone and hence a reaction rate significantly decrease with increasing the repetition number of “d”, due to increasing viscosity and hyrdophilicity of the glycerol derivative.


To avoid such decrease in the reaction rate, a large amount of a reaction solvent is required, which decreases yield per volume and hence cost performance. Said problem of poor miscibility is critical in modification of a silicone with a polyglycerol having higher degree of polymerization. Generally, modification with a polyglycerol having a molecular weight over 5,000 is very difficult. Particularly, in modifying the silicone with a small amount of polyglycerol derivative, the polyglycerol derivative tends to exist in a separate phase from the silicone or precipitates, making a reaction product cloudy.
Another drawback is that a hydroxyl group in a polyglycerol having an aliphatic unsaturated group tends to react with SiH group to hinder the addition reaction of the unsaturated group with SiH group and decrease a shelf life of the modified-silicone product.
Such dehydrogenation reaction of SiH with OH group can be suppressed by reacting α,ω-organohydrogensiloxane, which has a higher reactivity in the addition reaction, with a glycerol derivative having one aliphatic unsaturated bond. However, it cannot prevent a reaction product from being cloudy. To prepare a glycerol-modified silicone with a higher molecular weight, a polyglycerol with a higher molecular weight is required, because reaction sites of α,ω-organohydrogensiloxane are limited to the terminals. Such a high molecular weight polyglycerol is less miscible with the siloxane.
By using the triglycerol of the formula below with its OH groups being blocked, the dehydrogenation can be avoided. However, to release the blocking group after the reaction with a silicone, very severe reaction conditions are required, which causes a scission of the silicone chain, so that desired reaction product may not be obtained reproducibly.


Thus, a purpose of the present invention is to provide a glycerol-modified silicone having a good compatibility with oil agents conventionally used for a cosmetic and a good emulsifying activity to be advantageously used for a cosmetic and to provide a method of producing the same without the aforesaid problems in producing a glycerol-modified silicone.
SUMMARY OF THE INVENTION
As the result of extensive studies, the present inventors have found that a polyglycerol-modified silicone having a higher molecular weight than a conventional one can be obtained, without getting the polyglycerol-modified silicone cloudy, by subjecting α,ω-organohydrogensiloxane and a glycerol derivative to an alternating addition reaction, which glycerol derivative has a relatively low molecular weight and an aliphatic unsaturated group at both terminals. In addition, it has been found that polyglycerol-modified silicones with various contents of glycerol can be prepared by varying a ratio of a degree of polymerization of the siloxane to that of the polyglycerol.
Thus, the present invention is an alternating copolymer comprising a repeating unit of α,ω-organohydrogensiloxane residue (A) and a repeating unit of a glycerol derivative residue (B) having 1 to 11 hydroxyl groups, the copolymer having the number of a repeating unit (AB) of from 2 to 100.
Another aspect of the present invention is a process for preparing the aforesaid alternating copolymer comprising a step of reacting α,ω-organohydrogensiloxane having an SiH bond at both terminals with a glycerol derivative having an aliphatic unsaturated bond at both terminals.
The alternating copolymer of the present invention is clear, and a cosmetic comprising the copolymer has a reduced tackiness, while maintaining affinity to the skin, light spreadability on the skin to give a moisturized sensation. The applied cosmetic on the skin is durable and has a shiny finish of an expensive-looking.
A cosmetic comprising the alternating copolymer of the present invention as an emulsifier is very stable and the quality thereof does not change with temperature change or passage of time.
Moreover, the alternating copolymer may be added to a paint to prevent blocking or to improve flatness, smoothness and abrasion resistance of an applied paint.

PREFERRED EMBODIMENT OF THE INVENTION
The present copolymer is an alternating copolymer comprising a repeating unit of α,ω-organohydrogensiloxane residue (A) and a repeating unit of a glycerol derivative residue (B) having 1 to 11 hydroxyl groups. The silicone, α,ω-organohydrogensiloxane, is an organopolysiloxane having a hydrogen atom at both terminals. The glycerol derivative residue (B) has one hydroxyl group when the glycerol derivative is monoglycerol derivative, or 2 to 11, preferably 2 to 5, and more preferably 2 to 4 hydroxyl groups when the glycerol derivative is polyglycerol derivative. It is considered, without intending to limit the invention, that the alternating locations of the residue (A) with residue (B) is one of the reasons for the clearness, good emulsifying activity and miscibility with an oily agent. The number of the repeating unit (AB) ranges from 2 to 100, preferably 3 to 30, from the viewpoints of fluidity and solubility at room temperature.
Preferably, the repeating unit (AB) is represented by the following formula (1).

wherein, R 1 may be the same or different and is a group having 1 to 10 carbon atoms selected from the group consisting of alkyl, aryl, aralkyl, amino-substituted alkyl, and carboxyl-substituted alkyl groups, a part of which hydrogen atoms may be replaced with halogen atoms, R 2 may be the same or different and is an alkyl group having 11 to 30 carbon atoms, a part of which hydrogen atoms may be replaced with halogen atoms, Q is a divalent organic group having 3 to 20 carbon atoms and may comprise an ether bond and/or an ester bond, G is a mono- or poly-glycerol residue, a is an integer of from 2 to 100, b is an integer of from 0 to 100, and

c is an integer of from 2 to 100.


In formula (1), R 1 and R 2 are monovalent organic functional groups which do not have an aliphatic unsaturated bond. R 1 may be the same or different and is a group having 1 to 10 carbon atoms selected from the group consisting of alkyl, aryl, aralkyl, amino-substituted alkyl, and carboxyl-substituted alkyl, part of which hydrogen atoms may be replaced with halogen atoms. Examples of R 1 include alkyl groups such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, and decyl groups; cycloalkyl groups such as cyclopentyl and cyclohexyl groups; aryl groups such as phenyl and tolyl groups; aralkyl groups such as benzyl and phenetyl groups; amino-alkyl groups such as 3-aminopropyl, and 3-[(2-aminoethyl)amino]propyl group; carboxyl-substituted alkyl group such as 3-carboxylpropyl group; and trifluoropropyl and nonafluorooctyl groups.
R 2 may be the same or different and is an alkyl group having 11 to 30 carbon atoms part of which hydrogen atoms maybe replaced with halogen atoms, such as undecyl, dodecyl, tridecyl, tetradecyl, hexadecyl, octadecyl, behenyl and partly fluorinated alkyl groups.
In formula (1), Q is a divalent organic group having 3 to 20 carbon atoms and may comprise an ether bond and/or an ester bond such as —(CH 2 ) 2 —, —(CH 2 ) 3 —, —CH 2 CH(CH 3 )CH 2 —, —(CH 2 ) 4 —, —(CH 2 ) 5 —, —(CH 2 ) 6 —, —(CH 2 ) 7 —, —(CH 2 ) 8 —, —(CH 2 ) 2 —CH(CH 2 CH 2 CH 3 )—, —CH 2 —CH(CH 2 CH 3 )—, —(CH 2 ) 3 —O—(CH 2 ) 2 —, —(CH 2 ) 3 —O—(CH 2 ) 2 —O—(CH 2 ) 2 —, —(CH 2 ) 3 —O—CH 2 CH(CH 3 )—, and —CH 2 —CH(CH 3 )—COO(CH 2 ) 2 —, among which —(CH 2 ) 3 — is preferred.
In formula (1), G is a mono- or poly-glycerol residue. Typically, G may have a following chemical structure of (2), (3) or (4). In these formula, s, t, u, and v are integers of from 0 to 10. Examples of G include residue of monoglycerol, diglycerol, triglycerol, tetraglycerol, octaglycerol, decaglycerol, hexadecaglycerol, and octadecaglycerol. A part of hydroxyl groups may be replaced with alkoxyl groups or ester groups.


Preferably, s, t, u, and v are integers of from 1 to 9, and more preferably s, t, and u+v are integers of from 1 to 4.
Referring back to formula (1), a is an integer of from 2 to 100, preferably, from 10 to 60 and b is an integer of from 0 to 100. Preferably, b is 10 to 50% of a, that is from 1 to 50, in order for the alternating copolymer to be miscible with both a silicone oil and an ester oil. In formula (1), c is an integer of from 2 to 100, preferably, from 3 to 30. If c is larger than said upper limit, a copolymer may be too viscous to handle easily. A copolymer with c being smaller than said lower limit may not give a stable emulsion.
The present alternating copolymer can be prepared by subjecting the α,ω-orgnohydrogenpolysiloxane of the formula (5) shown below and mono- or polyglycerol derivative to an addition reaction in the presence of a platinum or rhodium catalyst, which mono- or polyglycerol derivative has an unsaturated group at both terminals, for example, triglycerol dially ether of the formula (i) or (ii).


Triglycerol dially ether of the formula (i) or (ii) may be prepared by adding 2 molar allylglycidyl ether dropwise to 1 molar triglycerol and subjecting the mixture to an addition reaction. Preferably, the reaction is carried out at a temperature of 60 to 120 degrees C. After the reaction, the catalyst is neutralized and, then, volatile substances having a lower boiling point than that of triglycerol dially ether are removed by distillation.
Triglycerol dially ether thus obtained is considered to be a mixture of the compounds of the formulae (i) and (ii) which is typically a pale yellow liquid having a viscosity of 330 mm 2 /s, hydroxyl number of 523 KOH mg/g, unsaturation of 6.13 meq/g. The hydroxyl number and unsaturation are nearly equal to theoretical values of 525 and 6.24, respectively, indicating that the dially ether obtained by the aforesaid method has two unsaturated groups per molecule.
A dially ether with a higher molecular weight can be prepared in the same manner as described above, by using diglycerol or triglycerol in place of glycerol.
A ratio of α,ωorgnohydrogenpolysiloxane of the formula (5) and the polyglycerol dially ether of the formula (i) and/or (ii) is such that a molar ratio of SiH group of the α,ω-orgnohydrogenpolysiloxane to CH═CH 2 group of the polyglycerol dially ether, SiH/CH═CH 2 , is equal to or greater than 0.5 and smaller than 1.5, preferably equal to or greater than 0.8 and smaller than 1.2.
The aforesaid addition reaction is preferably carried out in the presence of a platinum or rhodium catalyst. Preferred catalysts are chloroplatinic acid, alcohol-modified chloroplatinic acid, and chloroplatinic acid-vinyl siloxane complex.
The amount of the catalyst may be an effective amount, but 500 ppm or less, particularly, 20 ppm or less as platinum or rhodium are preferred. The aforesaid addition reaction may be carried out in an organic solvent if necessary. Examples of the organic solvent include aliphatic alcohols such as methanol, ethanol, 2-propanol, and butanol; aromatic hydrocarbons such as toluene and xylene; aliphatic or alicyclic hydrocarbons such as n-pentane, n-hexane, and cyclohexane; and halogenated hydrocarbons such as dichloromethane, chloroform, and carbon tetrachloride. When such solvent is used, the addition reaction is preferably carried out for 1 to 10 hours while refluxing the solvent.
After the addition reaction, unreacted allyl ether group may be killed by hydrogenation, or alkylation to reduce odor. An antioxidant such as tocopherol or BHT may be added to the copolymer.
