BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silicone emulsion composition suitable as a raw material for hair cosmetics such as shampoos and rinses, and a cosmetic using the same.

[0002]

2. Description of the Related Art Conventionally, silicones have been used in hair cosmetics such as shampoos and rinses for the purpose of imparting luster (gloss) and smoothness to hair.

As means for adding silicone to cosmetics, there are a method of adding silicone as it is and stirring and dissolving it, and a method of adding solubilized or emulsified silicone in advance.

However, in these conventional silicone emulsion compositions, the emulsifier causes coagulation during low-temperature storage, or causes separation or white turbidity during high-temperature storage. There have been problems in that it is difficult to develop properties and that the properties of the hair cosmetic itself are impaired.

Further, when a highly polymerized dimethylpolysiloxane is used as a base oil of a silicone emulsion composition, the emulsified particle diameter becomes large even if emulsified by a mechanically high shearing force, resulting in poor storage stability. There was a problem. In this case, the storage stability is improved when a thickener is used in combination, but there is a problem that the properties of the hair cosmetic are impaired by the thickener.

[0007] Therefore, there has been a demand for the development of a silicone emulsion composition which has good storage stability, is excellent in expressing the inherent properties of silicone, and does not impair the properties of hair cosmetics such as shampoos and rinses.

[0008] The present invention has been made to meet such a demand, has good storage stability, is capable of fully expressing the inherent characteristics of silicone, and has the characteristics that when used in hair cosmetics and the like. It is an object of the present invention to provide a silicone emulsion composition that does not impair and a cosmetic using the same.

[0017]

Embodiments of the present invention will be described below.

The polyorganosiloxane of the component (A) used in the present invention is a component for imparting gloss and smoothness to the hair, and basically has a linear siloxane skeleton. Although it may have some branches, it is preferable that the whole molecule has a linear structure.
Preferred number of siloxy units is about 10 to 100,000,
More preferably, it is about 100 to 10,000.

Examples of the organic group bonded to the silicon atom in the molecule include an alkyl group such as methyl, ethyl, propyl, butyl, and hexyl; a cycloalkyl group such as cyclohexyl; an alkenyl group such as vinyl and allyl; and phenyl and tolyl. And a group in which a hydrogen atom bonded to a carbon atom of these groups is substituted with a halogen atom, a cyano group, an amino group, etc., for example, a chloromethyl group, a 3,3,3-trifluoropropyl group, a cyanomethyl group , N- (2-aminoethyl) -3-aminopropyl group, 3-aminopropyl group and the like. The other group bonded to the silicon atom may partially include an alkoxy group, a hydroxyl group, a hydrogen atom, and the like.

In the present invention, it is particularly preferable to use polydimethylsiloxane or amino-functional polyorganosiloxane as the polyorganosiloxane of the component (A). Amino-functional polyorganosiloxanes include:
Those having an amino content of 0.02 to 3.0 meq / g and containing structural units represented by the following formulas (i) and (ii) ((i) :( ii) = 1: 2 to 1: 1300 (Molar ratio)). (I) R ¹ aQbSiO (4-ab) / 2 (wherein, R ¹ is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 6 carbon atoms, and Q is —R ² NHZ (where R ² is Carbon and hydrogen; carbon, hydrogen and oxygen; or a divalent linking group containing carbon, hydrogen and sulfur atoms, Z is a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or —CH ₂ CH ₂ NH ₂ ) , A
Is a number from 0 to 2; b is a number from 1 to 3; a + b ≦ 3) (ii) R ³ cSiO (4-c) / 2 (wherein R ³ is a substituted or unsubstituted C 1 to C 6 A monovalent hydrocarbon group, c is a number of 1 to 3) Examples of the terminal group of the molecular chain include a triorganosilyl group or a group in which a hydroxyl group is bonded to a silicon atom instead of a part of the organic group. And preferably a trimethylsilyl group and a dimethylhydroxysilyl group, with a trimethylsilyl group being particularly preferred.

As such a polyorganosiloxane as the component (A), those in a range generally called silicone oil or silicone raw rubber soluble in an organic solvent are used.

In addition, because of the easiness of emulsification of the emulsion and the easiness of expressing the characteristics of the component (A) when the cosmetic is used, those having a viscosity of 10 to 100,000,000 centistokes (cSt) at 25 ° C. Particularly preferred is one having a viscosity at 25 ° C of 10,000 to 50,000,000 cSt.

The polyorganosiloxane of the component (A)
One type may be used alone, or two or more types may be used in combination.

The (B) component (a) nonionic surfactant and (b) carboxylic acid type amphoteric surfactant used in the present invention act as an emulsifier and as a storage stabilizer for the composition. Is also provided. That is, the component (B) is an essential component for improving the storage stability of the composition, in addition to dispersing the polyorganosiloxane of the component (A) uniformly in water. The component (B), when added to hair cosmetics, sufficiently expresses the properties of the polyorganosiloxane as the component (A) without impairing its properties.

Of the component (B), the nonionic surfactant (a) mainly serves to uniformly disperse the polyorganosiloxane (A) in water. Also,
By adjusting the type and amount of the nonionic surfactant (a), the emulsion particle size can be controlled. On the other hand, the carboxylic acid type amphoteric surfactant (b) serves mainly as a storage stabilizer.

Examples of the nonionic surfactant (a) include glycerin fatty acid esters such as glyceryl monolaurate, glyceryl monomyristate and glyceryl monooleate; polyglycerin fatty acid esters having similar fatty acid residues, and polyoxyethylene. Glycerin fatty acid ester and polyoxyethylene fatty acid ester; polyoxyethylene butyl ether, polyoxyethylene lauryl ether, polyoxyethylene tridecyl ether, polyoxyethylene cetyl ether, polyoxyethylene isocetyl ether, polyoxyethylene stearyl ether, polyoxyethylene Polyoxyethylene alkyl ethers such as ethylene oleyl ether and polyoxyethylene behenyl ether; polyoxyethylene octylphenyl Ether, polyoxyethylene alkylphenyl ether such as polyoxyethylene nonylphenyl ether; oxyethylene / oxypropylene block copolymer; polyether-modified polydimethylsiloxane; and the like. Among them, polyoxyethylene lauryl ether, polyoxyethylene Preference is given to ethylene cetyl ether, polyoxyethylene stearyl ether and polyoxyethylene oleyl ether. One of these nonionic surfactants may be used alone.
A mixture of more than one species may be used.

Examples of the carboxylic acid-type amphoteric surfactant (b) include betaine-type coconut oil fatty acid amidopropyl betaine, lauric acid amidopropyl betaine, lauryl dimethylaminoacetic acid betaine, and coconut oil alkyl betaine. Among them, coconut oil fatty acid amidopropyl betaine is preferred. One of these betaine-type amphoteric surfactants may be used alone, or two or more thereof may be used in combination.

In the present invention, the total amount of the (B) component (a) nonionic surfactant and (b) carboxylic acid type amphoteric surfactant is 100 parts by weight of the component (A) polyorganosiloxane. On the other hand, it is 10 to 200 parts by weight, preferably 30 to 180 parts by weight. When the total amount of (a) the nonionic surfactant and (b) the carboxylic acid type amphoteric surfactant is less than 10 parts by weight, the polyorganosiloxane of the component (A) is well dispersed in the obtained emulsion composition. It becomes difficult to perform the storage or the storage stability decreases.
On the other hand, when the amount exceeds 200 parts by weight, the viscosity of the obtained composition increases, the fluidity becomes poor, and the dispersion in the cosmetic becomes difficult.

The weight ratio (a) / (b) of each of the components (a) and (b) also greatly affects the storage stability of the composition and the properties of the cosmetic. In the present invention, (a) /
(B) (weight ratio) is in the range of 1/20 to 1 / 0.1. Preferably it is in the range of 1/10 to 1/1. When the proportion of the component (a) is more than the above range, storage stability may be reduced,
When added to cosmetics, the properties may be reduced due to the effect of component (a). Further, when the proportion of the component (b) is more than the above range, the emulsifying power is reduced, and a good emulsion cannot be obtained, or when added to cosmetics, its properties are deteriorated due to the effect of the component (b). There is.

In the present invention, water as the component (C) is blended as a dispersion medium. This is for obtaining a uniform emulsion composition by dispersing or dissolving the polyorganosiloxane of the component (A) and other components.

The amount of the component (C) water is from 20 to 4 parts by weight based on 100 parts by weight of the component (A) polyorganosiloxane.
00 parts by weight, preferably 25 to 350 parts by weight. If the amount of water is less than 20 parts by weight, the amount of the polyorganosiloxane, which is a hydrophobic oil, is too large, so that the emulsion does not invert from W / O type to O / W type, and water does not form a continuous layer. There are cases. On the other hand, when the amount of water exceeds 400 parts by weight, the concentration of the polyorganosiloxane is too low, so that the efficiency of emulsification may deteriorate.

The silicone emulsion composition of the present invention may optionally contain an organic solvent in order to dissolve the polyorganosiloxane (A) and facilitate emulsification. Organic solvents include aliphatic hydrocarbons such as n-hexane, n-heptane, cyclohexane, methylcyclohexane, mixed solvents of isoparaffin, gasoline, rubber volatile oil, mineral spirits and kerosene; aromatic hydrocarbons such as toluene and xylene Hydrogens; n-butyl ether,
