Description

  The present invention relates to a skin cosmetic composition. More specifically, the present invention can maintain a skin shine recovery effect for a long time, is excellent in a dry and moist feeling when applied to the skin, and has a dispersion stability. The present invention also relates to an excellent skin cosmetic composition.

  The so-called T zone, which extends from the forehead to the nose, has a large amount of sebum secretion, and is particularly a part that feels sticky and sticky for people with oily skin. In addition, people with dry skin may feel dryness and roughness. Furthermore, for people with mixed skin, both of the above-mentioned problems of skin quality exist, and the T zone feels shine and stickiness, and the portion other than the T zone feels dryness and roughness.

Conventionally, skin cosmetics using powder have been known in order to give a shine-proofing effect to shine and stickiness against such problems, and to obtain a smoother feeling. In order to absorb more sebum, which is considered to be one of the causes of shine, powders with a large amount of sebum absorption may be used. There are many. For example, a porous inorganic silica powder has a large amount of sebum absorption, but has a higher specific gravity than an organic powder. Therefore, in an aqueous dispersion system to which a powder having a large specific gravity is added, the dispersion stability of the powder in the skin cosmetic composition becomes insufficient, the powder settles, and caking (the contained powder is in the liquid phase). There is a problem in that it solidifies on the bottom surface inside and does not disperse even when shaken. Therefore, a method has been proposed in which a polymer is added to an aqueous dispersion system to which powder is added to increase the viscosity and improve the dispersion stability of the powder (see, for example, Patent Document 1). However, if the amount of the polymer added is increased in order to improve the dispersion stability of the powder having a large specific gravity, stickiness occurs when the skin cosmetic composition is used, and the feeling of use deteriorates. There was a problem that the objective shine prevention effect and the smooth feeling could not be obtained sufficiently.
Moreover, when applied to the skin, it is a gel-like cosmetic that has a good feeling of stickiness and does not have shine due to sebum, as a hydrophobic oil-absorbing powder having an oil absorption of squalane of 2.0 g / g or more, an alkyl-modified carboxyvinyl polymer, and Cosmetics combining basic substances have been proposed (see, for example, Patent Document 2). However, the cosmetics have a problem that the shine prevention effect cannot be maintained for a sufficient time.
On the other hand, it is known to combine a moisturizer to give moisture feeling to dryness and rustling, but if emphasis is placed on moisture feeling, the shine prevention effect and the smooth feeling are insufficient, and the shine prevention effect If the emphasis was placed on the smooth feeling, there was a problem of lack of moisture.

  In addition, it is possible to obtain a moist feeling without causing oiliness or stickiness when applied to the skin. In order to give a sufficient moisturizing effect to the skin after application, both acrylic acid and alkyl methacrylate are used. A cosmetic suitable for skin after shaving, characterized by containing a polymer, spherical powder and volatile silicone has been proposed (for example, see Patent Document 3). However, the cosmetics do not mention the shine prevention effect.

  In addition, regarding the persistence of the shine prevention effect, there has been a demand for a skin cosmetic that can maintain the effect for a long time, such as a shine prevention agent containing a hydrocarbon wax (see, for example, Patent Document 4). Yes.

  Therefore, there is a demand for a skin cosmetic composition that can maintain the skin's shine protection effect for a long time, has a smooth and moist feeling when applied to the skin, and is excellent in dispersion stability. This is the current situation.
