Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a make-up cosmetic composition, and more particularly to a make-up cosmetic composition having good spreadability and paste, smoothness, and a smooth feel.

[0002]

Makeup cosmetics are used to give the skin a bright and vibrant colour. In general, makeup cosmetics are blended with various organic powders in order to impart coatability, spreadability (spreading), oil absorption, adhesiveness (paste), colorability, and glitter. Examples of the organic powder include organic resin powder such as polyethylene resin, polypropylene resin, polyamide resin, acrylic resin, vinyl chloride resin, epoxy resin, and polystyrene resin, nylon resin powder (see Japanese Patent Laid-Open No. 5-25019), Polymethylsilsesquioxane powder (JP-A-63 / 1988)
-297313, JP-A-1-268615, JP-A-5-25019 and JP-A-5-14.
No. 8120), silicone rubber powder (Japanese Patent Application Laid-Open No. 6-68242).
JP-A-1-194009 and JP-A-2-243612
(See Japanese Patent Publication).

[0003]

However, since the organic resin powder and the polymethylsilsesquioxane powder are not elastic and have extremely high hardness, makeup cosmetics prepared by blending these powders are not suitable for the skin. There was a problem that the glue and spread were not good, and it felt rough and felt a foreign body. Further, a makeup cosmetic prepared by crushing a silicone rubber as proposed in JP-A-61-194009 and blending an irregularly shaped silicone rubber powder is not satisfactory in spreading and spreading on the skin. There was a problem. In addition, JP-A-2-2436
A makeup cosmetic prepared by blending a silicone rubber powder containing 0.5 to 80% by weight of a non-crosslinking silicone oil as proposed by No. 12 has a low hardness of the silicone rubber powder itself and has an adhesive property. Therefore, there is a problem in that the spread and spread on the skin are poor and the product feels sticky.

The present inventors have arrived at the present invention as a result of extensive studies on the above problems. That is, an object of the present invention is to provide a makeup cosmetic which has good spreadability and paste, is smooth, and has a smooth feel.

[0005]

Means for Solving the Problem and Its Action The makeup cosmetic of the present invention has an average particle diameter of 0.1 to 200 μm.
m of spherical silicone rubber powder (however, the silicone rubber forming the powder has a JIS A hardness of 35 to 80) in an amount of 0.1 to 50% by weight. Hereinafter, the makeup cosmetic of the present invention will be described in detail.

As the makeup cosmetic of the present invention, for example, the skin color is adjusted to give a bright and transparent feeling to the skin,
A white powder that suppresses sweat and sebum, and prevents oil swelling, a beautiful skin color, and a foundation that imparts a lustrous, supple, and transparent feeling to the skin and covers spots, freckles, and the like on the skin;
Color your lips, put lipstick to accent your face, put red lipstick on your cheeks, give your face a bright and healthy look, and correct the contours of your face.
Examples include blusher to give a three-dimensional effect, and eye shadow to give a richer expression to the eyes by shading the eyes and making them look three-dimensional. The composition of the present invention varies depending on its dosage form, and the dosage form is not particularly limited, and examples thereof include liquid, creamy, waxy, and powdery forms.

In the makeup cosmetic composition of the present invention, the silicone rubber powder, which is an essential component, must have an average particle size within the range of 0.1 to 200 μm. This is because it is difficult for the silicone rubber powder having an average particle size of less than 0.1 μm to exhibit the effects of the present invention, and the silicone rubber powder having an average particle size of more than 200 μm makes it possible to obtain a squeaky feeling or a messy foreign substance. Because there is a feeling. In addition, the variation in particle size of the silicone rubber powder tends to improve the usability, and in order to obtain a suitable usability, the particle size is preferably 250 μm or less. The shape of the silicone rubber powder needs to be spherical, but it does not have to be strictly spherical, and for example, it may be spherical having an elliptical cross section, but it is preferably spherical. The JIS A hardness (specified in JIS K 6301) of the silicone rubber forming this silicone rubber powder must be within the range of 35-80. This is because the powder made of silicone rubber having a JIS A hardness of less than 35 gives a sticky feeling, and the powder made of silicone rubber having a hardness of more than 80 gives a rough feeling. ,
This is because you will feel a foreign body.

The method for producing the silicone rubber powder is not particularly limited, and for example, a thermosetting liquid silicone rubber composition is sprayed in hot air so as to have a spherical shape with an average particle diameter of 0.1 to 200 μm. Method of curing, thermosetting liquid silicone rubber composition having an average particle size of 0.1 to 20
A method of dispersing in water so as to form a spherical shape of 0 μm and curing (Japanese Patent Laid-Open No. 63-77942 / 64-7).
(See Japanese Patent No. 0558), and the latter method is preferable because it is possible to prepare a spherical silicone rubber powder having a small average particle diameter and a small variation in particle diameter.

In the makeup cosmetic composition of the present invention, the compounding amount of the silicone rubber powder varies depending on the dosage form.
Generally, it is necessary to be within the range of 0.1 to 50% by weight, and in the case of press-type makeup cosmetics, 1 to
It is preferably in the range of 50% by weight, and in the case of a liquid makeup cosmetic, it is preferably in the range of 0.1 to 30% by weight. This is because if the compounding amount of this silicone rubber powder is less than 0.1% by weight, it is difficult to exhibit the effects of the present invention, and if this amount is 50% by weight.
This is because, if it exceeds the range, the stability of the dosage form is lowered when it is made into a cream or stick, and the usability as a makeup cosmetic is reduced.
