DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a makeup cosmetic, and more particularly to a stable makeup cosmetic with excellent water resistance, sweat resistance and oil resistance, and long lasting makeup. The makeup cosmetics referred to here include, in addition to regular makeup cosmetics,
It also includes the base cosmetics used as the base.

[Technical background of the invention and its problems] Makeup has various forms and types, such as solid foundation, solid eye shadow, oil foundation, and lipstick. There are also emulsifying foundations, but they all contain talc, kaolin, iron oxide,
It is characterized by containing a large amount of inorganic pigments such as titanium oxide, titanium, and mica-based pearl pigments, and organic pigments such as nylon, cellulose, and tar pigments.

These makeup cosmetics tend to cause makeup to come off due to sebum, sweat, or the oil content of the cosmetics, and there is a problem in that makeup comes off noticeably due to frequent sweating, especially in the summer, and an improvement has been desired. Also, with the recent trend of sports as a leisure activity, it has become commonplace for people to wear makeup while playing sports. These makeup cosmetics, which are called sports makeup and summer makeup, are required to have greater water resistance, sweat resistance, and oil resistance than conventional makeup products.

In addition, base cosmetics are used to improve the adhesion of makeup cosmetics and give a beautiful finish, but it is rare to see conventional makeup cosmetics that have been designed to make makeup last longer. do not have.

In order to solve these problems, various attempts have been made to incorporate polyorganosiloxanes. However, the materials used in these conventional makeup cosmetics are chain polydiorganosiloxane and Rx5iO.

An object of the present invention is to provide a makeup cosmetic that has excellent water resistance, sweat resistance, and oil resistance, and has good cosmetic durability.

[Structure of the invention]

In order to overcome the above problems, the present inventors have conducted intensive research and found that the above object can be achieved by blending a special silicone resin, and have hereby accomplished the present invention.

That is, the present invention is based on the general formula (a) (where R is a substituted or unsubstituted monovalent hydrocarbon group of the same or different type, X is a hydroxyl group or a hydrolyzable group, and n is 10
(an integer of ~20.000) (hereinafter referred to as component (a)) and (b) a siloxane unit represented by the formula R15iOo, s and a siloxane unit represented by the formula Sing. (where P is a substituted or unsubstituted monovalent hydrocarbon group of the same or different kind), which has at least one hydroxyl group or hydrolyzable group bonded to a silicon atom in one molecule. This makeup cosmetic is characterized by containing an organic silicone resin obtained by condensing one or more organosiloxanes (hereinafter referred to as component (b)).

The polydiorganosiloxane (a) used in the present invention has hydroxyl groups or hydrolyzable groups substantially at both ends. Examples of hydrolyzable groups include condensation-reactive groups such as alkoxy groups, ketoxime groups, and aminoxy groups, and alkoxy groups such as methoxy groups, ethoxy groups, propoxy groups, and butoxy groups are common. It is substantially linear, but may contain up to 10% branched chain. In addition, the average degree of polymerization n is 10 to 20,000, and the molecular weight is about 700 to 1.500,000.
This corresponds to

Component (b), which is a raw material for the organic silicone resin used in the present invention, is well known to those skilled in the art, and includes:
This includes, for example, at least one of water glass, orthoethylsilicate, and edyl polysilicate that constitutes the SiO□ unit, and trimethylchlorosilane, trimethylmethoxysilane, triphenylchlorosilane, phenyldimethylmethoxysilane, and dimethyl that constitute the Rx5iOo, s unit. It can be obtained by cohydrolytic condensation with at least one type of silane such as vinylchlorosilane and dimethylvinylmethoxysilane. The molar ratio of the siloxane unit represented by 2R, SiO,... and the siloxane unit represented by the formula SiO□ is 0.5 to 1.0, and the hydroxyl group or hydrolyzable group bonded to a silicon atom in one molecule A copolymer having at least one of
It is desirable to have 00.

The organic silicone resin of the present invention is a partial condensation of component (a) and component (b). The ratio of component (a) and component (b) constituting this organic silicone resin is 8
0:20 to 20:80 is preferred. This partial condensation reaction is carried out without a catalyst or under a basic catalyst. Examples of basic catalysts include metal hydroxides such as sodium hydroxide and lithium hydroxide, aliphatic amines such as trimethylamine and diethylamine, Examples include aromatic amines such as aniline and methylaniline, and quaternary ammonium compounds such as olkalammonium hydroxide.

The amount of the organic silicone resin of the present invention is 0.1 to 50% by weight based on the total amount of the makeup cosmetic.

If it is less than 0.1% by weight, sufficient effects cannot be obtained, and if it exceeds 50% by weight, it becomes difficult to dissolve in low boiling point solvents.

The makeup cosmetic of the present invention usually contains the following solvent, and a low boiling point solvent that evaporates at room temperature is used. Preferred examples of the low boiling point solvent include low boiling point linear silicones, cyclic silicones, low boiling point isoparaffinic hydrocarbons, and fluorochloro-substituted hydrocarbons.

Low-boiling linear silicones are represented by the following general formula, and specific examples include hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, and dodecamethylpentasiloxane.

(In the formula, p represents an integer of O to 5.) Cyclic silicones are represented by the following general formula, and specifically include octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, etc. .

Furthermore, examples of the fluorochloro-substituted hydrocarbon include trichlorotrifluoroethane and tetrachlorodifluoroethane.

The above-mentioned low-boiling point solvent can be used in any one kind or in combination of two or more kinds, and the total blending amount is 99% by weight of the total amount of hair cosmetics.
or less, preferably 10 to 90% by weight.

In addition to the above components, lower alcohols such as ethanol and IPA may be added. Furthermore, there are silicone derivatives as components that can be added to the present invention, such as linear dimethyl silicone oil, methylphenyl silicone oil, polyether-modified silicone oil, amino-modified silicone oil, epoxy-modified silicone oil, fluorine-modified silicone oil, etc. One or more components can be added.

This silicone derivative is effective for modifying organic silicone resin films. Although it is well known that low molecular weight plasticizers are added to modify resin films, conventional plasticizers such as phthalic acid derivatives and higher alcohol polyoxyethylene ethers are unsuitable from the viewpoint of compatibility. In this respect, silicone derivatives have good compatibility with organic silicone resin systems, effectively plasticizing the resin film, strengthening its adhesion to hair, and making it possible to obtain an ideal film that does not lose its smoothness or stickiness. can.

The blending amount of these silicone derivatives is 99% by weight or less based on the total amount of the hair cosmetic. If it exceeds 99% by weight, the organic silicone resin will not form a film, which is not preferable.

The formulation of the hair cosmetic composition of the present invention is arbitrary, and may be any of a solubilized system, an emulsified system, a powder dispersion system, a two-layer system of oil-water, and a three-layer system of oil-water and powder.

In the case of an emulsion system, the oil phase containing the organic silicone resin is generally emulsified with a nonionic surfactant, cationic surfactant, anionic surfactant, or a mixture thereof. Preferred is a method in which a mixture of a surfactant and a water-soluble polyhydric alcohol is prepared and then mixed with an oil phase to obtain an emulsified composition.

Water-soluble polyhydric alcohol is a polyhydric alcohol having two or more hydroxyl groups in the molecule, and specifically includes ethylene glycol, propylene glycol, 3-butylene glycol, 1,4-butylene glycol, and dipropylene glycol. , glycerin, polyglycerin (diglycerin, triglycerin, tetraglycerin, decaglycerin, etc.), glucose, maltitol, sucrose, fructose xylitol, erythritol, starch-degrading sugar-reducing alcohol, and one or two of these. The above are arbitrarily selected and used.

In addition to the organic silicone resin according to the present invention, the following oils may be used as the oil constituting the oil phase of the emulsified cosmetic.

i.e. olive oil, coconut oil, safflower oil, castor oil,
Oils and fats such as cottonseed oil, wax oils such as lanolin, jojoba oil, and carnauba wax, hydrocarbon oils such as liquid paraffin, squalane, petrolatum, and volatile isoparaffin, fatty acids, alcohols, and ester oils such as cetyl octoate and isopropyl myristate. , dimethylpolysiloxane,
These are oils commonly used in cosmetics, such as silicone oils and silicone resins such as methylphenylpolysiloxane.

The general blending amounts of the above ingredients are 0.5 to 10% by weight of the surfactant and 20 to 80% by weight of the oil phase containing the organic silicone resin based on the total amount of the hair cosmetic. In the case of the method of preparing a mixture with a polyhydric alcohol and mixing it with an oil phase to obtain an emulsified composition, the surfactant contains 1 to 2
0% by weight, the oil phase containing organosilicone resin is 10-70%
Weight%, water-soluble polyhydric alcohol is 5-3% of the total amount of cosmetics
It is preferable that the amount is 0% by weight and the amount is about 50 to 90% by weight based on the surfactant.

The emulsified cosmetic may be either a water-in-oil type or an oil-in-water type, but it is desirable to prepare the emulsified cosmetic so as not to lose its volatility, which is an advantage of the present invention.

In addition to the above-mentioned components, the makeup cosmetic of the present invention may include ultraviolet absorbers, antioxidants, preservatives, vitamins, etc., depending on the purpose, within a quantitative and qualitative range that does not impair the effects of the present invention.
Medicinal agents such as hormones and fragrances may be added.
