Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a water-in-oil type emulsion cosmetic, and more specifically, it exhibits a good emulsified state without increasing the viscosity of the outer phase, does not change with temperature or aging, and is applied. The present invention relates to a water-in-oil type emulsion cosmetic that spreads well on the skin and has a fresh and good feeling in use.

[0002]

2. Description of the Related Art Conventionally, water-in-oil type emulsion cosmetics have high stability by increasing the viscosity of the outer phase (oil phase) and blending solid / semi-solid type oil components. Since the product was obtained, it had a greasy and sticky feel, and was not highly evaluated as a cosmetic. However, thereafter, as an emulsification method containing a relatively large amount of water phase and capable of significantly reducing the solid / semisolid oil content in the oil phase, JP-A-53-21393 “water-in-oil type emulsifier composition” is used. , "JP-A-61-29033," water-in-oil type emulsion composition "and the like. However, the emulsified cosmetics containing these emulsified compositions also have a high stability by increasing the viscosity of the outer phase in the same manner, and thus have poor elongation when applied to the skin,
There was a drawback that the feeling was not sufficient. For this reason,
It has been desired to develop a water-in-oil type emulsion cosmetic which has good stability even if the viscosity of the outer phase is lowered, has good elongation, and has a fresh and fresh feeling.

[0003]

The present invention has been made in view of the above-mentioned problems of the prior art, and as a result of intensive studies by the present inventors, the present invention has revealed that it is a powder having a high oil absorption and a particle size of By using a mixed powder that is a combination of different powders in a specific weight ratio and a specific oil content, and by using an organically modified clay mineral as an emulsification aid, it has good elongation, a fresh feel, and good stability. It was found that a water-in-oil type emulsified cosmetic composition can be obtained, and the present invention has been completed.

That is, according to the present invention, (A) an average particle size of 2.0
˜5.0 μm particle size distribution of 1 to 15 μm organopolysiloxane elastomer spherical powder and (B) average particle size 0.2

(E) 0.01% of organically modified clay mineral to the total amount of cosmetics
It is a water-in-oil type emulsified cosmetic, characterized by comprising: ~ 1.0 wt% and (F) water.

The structure of the present invention will be described in detail below. The details of the organopolysiloxane elastomer spherical powder having an average particle size of 2.0 to 5.0 μm and a particle size distribution of 1 to 15 μm, which is the component (A) of the present invention, are described in JP-B-4-66446 and JP-A-2-243612. Publication and Japanese Patent Publication No. 4-1716

The average particle size of the component (B) is 0.2 μm.
The hydrophobized silica powder of m or less is obtained by subjecting the hydrophilic hydroxyl groups on the surface to trimethylsilylation or dimethylsilylation. Specifically, in the case of trimethylsilylated,
AEROSIL R813 (trade name of Nippon Aerosil Co., Ltd.), which is dimethylsilylated AEROS
IL R972, R974 (trade name of Nippon Aerosil Co., Ltd.) and the like can be mentioned.

The components (A) and (B) are used as a mixture, and the range thereof is such that the weight ratio of (A) to (B) is 1: 0.1 to 1: 5, and more preferably. 1: 0.1
It is 1: 3. If the mixing ratio of (A) and (B) is less than (B) 0.1 with respect to (A) 1, stability tends to be poor, and if it is 5 or more, stickiness is produced when used.

In the present invention, (C) the total oil phase component of 3
An oil phase containing 0% by weight or more of silicone oil is used, and this silicone oil is a component necessary for improving the feeling of use. The silicone oil to be blended is dimethyl polysiloxane, methylphenyl polysiloxane, cyclic dimethyl polysiloxane, methyl hydrogen polysiloxane, decamethyl polysiloxane, dodecamethyl polysiloxane, tetramethyl tetrahydrogen polysiloxane, highly polymerized methyl polysiloxane.
