Description

Description: TECHNICAL FIELD The present invention relates to a specific acyl group 2
The present invention relates to a cosmetic composition which contains a long-chain dipolar group-containing anionic surfactant, an organic fine particle powder, and water , thereby improving a feeling effect and a skin moisturizing effect. 2. Description of the Related Art Conventionally, cosmetics such as creams and emulsions have been imparted with a moist and rich feel after application,
Moreover, in order to have a sufficient skin moisturizing effect, a relatively large amount of moisturizing agents such as various oil-based components and glycerin have been blended. However, if you try to enhance the moisturizing effect by emphasizing the moist and rich feel, the oily feeling and sticky feeling at the time of application will increase, and it will be possible to simultaneously satisfy the sufficient moisturizing effect on the skin and the good feeling of use It was difficult. [0003] The present inventor has conducted intensive studies to improve such disadvantages of the prior art, and as a result,
It has been found that the above-mentioned drawbacks can be remarkably improved by incorporating a specific acyl group 2 long chain dipolar group-containing anionic surfactant, an organic fine particle powder and water in a specific compounding range, and to complete the present invention. Reached. [0004] That is , the present invention according to claim 1 of the present invention is directed to N, N'-bis (lauramide) ethane-

It is a cosmetic characterized by containing by weight . Next, an embodiment of the present invention will be described. In the present invention, the acyl group-containing two-chain dipolar group-containing anionic surfactant includes N, N'-bis ( lauramide ) ethane-N, N'-di (sodium acetate) and N, N'-bis ( myristamide ). Ethane-N, N′-di (sodium acetate), N, N′-bis ( palmitamide ) ethane-N,
N'-di (sodium acetate), N, N'-bis ( laura
Mido ) ethane-N, N'-di (sodium propionate), N, N'-bis ( myristamido ) ethane-N,

N, N'-di (potassium acetate), N, N'-bis ( milli
Stamide ) butane-N, N'-di (potassium acetate),
N, N'- bis (palmitamide) butane -N, selected from N'- di (potassium acetate). The compounding amount of the acyl group-containing two-chain bipolar group-containing anionic surfactant is 0.1 to 40.
It is in the range of weight%. If it is 0.1% by weight or less, the feel effect and the skin moisturizing effect are insufficient, and if it is 40% by weight or more, the viscosity of the system increases and the usability may deteriorate. [0006] Examples of the organic fine particle powder in the present invention include powdered husks of plant nuts (eg, walnuts) and powdered hinoki cypress. Further, examples of the organic fine particle powder in the present invention include polyethylene powder and polymethylsilsesquioxane powder (Tospearl 240, manufactured by Toshiba Silicone Co., Ltd.) Polyethylene powder is to be blended with ordinary cosmetics. The methylsilsesquioxane powder is a true spherical fine particle having an average particle diameter of 2 μm.The present invention comprising these polymethylsilsesquioxane powder together with an anionic surfactant containing an acyl group 2 and a long-chain dipolar group and water. cosmetics, oily feel during application, non-sticky, has a smooth feel and smooth, yet excellent conspicuously skin moisturizing effect. these organic
The substance fine particle powder is used also as a scrub agent when it is blended with a skin cleanser. The compounding amount of the organic fine particle powder of the present invention is in the range of 0.1 to 20% by weight. At 0.1% by weight or less, the feel effect and the skin moisturizing effect are insufficient, and
If the content is 0% by weight or more, the viscosity of the system may increase, and the usability may deteriorate . In the present invention, water is blended in the range of 20 to 80% by weight. [0007] In addition to the above essential components, the cosmetic of the present invention includes surfactants, powders, water-soluble polymers, pigments, fragrances, humectants, preservatives, etc., which are generally used in cosmetics. Agents, vitamins, plant extracts, proteins, and derivatives or degradation products thereof can be used in a total amount of 0 to 5% by weight. The cosmetic of the present invention can be made into various dosage forms such as a liquid, an aerosol, a paste, and a gel, if desired. The cosmetics of the present invention include facial cleansing creams, liquid facial cleansers, body shampoos, shampoos, makeup removers, cleansing cosmetics, and other cosmetics for cleaning the skin or hair, creams, emulsions, lotions, and the like. Applied to normal cosmetics. Hereinafter, the present invention will be described with reference to examples, but the present invention is not limited to these examples. Embodiment 1 The cosmetic of Formulation Example 1 thus obtained was significantly superior to the cosmetics of Formulation Examples 2 and 3 , which are comparative examples , in the feel effect and the skin moisturizing effect. The cosmetic of the present invention was prepared by the same formulation except that the amount of N, N'-bis ( lauramide ) ethane-N, N'-di (sodium propionate) was 45% by weight. This was slightly inferior to the cosmetic of Formulation Example 1 in the feel effect and the skin moisturizing effect. Also, N,
When the cosmetic of the present application was prepared with the same formulation except that the blending amount of N'-bis ( lauramide ) ethane-N, N'-di (sodium propionate) was 0.05% by weight. The effect and the skin moisturizing effect were slightly inferior to the cosmetic of Formulation Example 1 . Furthermore, where addition to the 25 wt% the amount of spherical polymethylsilsesquioxane powder which was prepared application of cosmetics in the same formulation, this cosmetic formulation examples 1 in feel effect and skin moisturizing effect It was slightly inferior to the fee . Further, when further addition to the 0.05% the amount of spherical polymethylsilsesquioxane powder which was prepared application of cosmetics in the same formulation, this is of Formulation Example 1 in feel effect and skin moisturizing effect Slightly inferior to cosmetics . [0013] As described above, it is apparent that the present invention provides a cosmetic having an improved feel and skin moisturizing effect.
