Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a specific acrylic resin.
The present invention relates to a powder cosmetic containing a silicone-based graft copolymer, a fluorine-based oil and / or a fluorine-modified silicone oil, and a powder. More specifically, it has a smooth elongation and spread, and has good water resistance and oil resistance. Therefore, the present invention relates to an excellent powder cosmetic which does not cause caking at the time of use in solid powder cosmetics because it has excellent makeup persistence and good skin familiarity, so that there is no feeling of burden on the skin.

[0002]

2. Description of the Related Art Conventionally, as a method for smoothing the spread of powder cosmetics, there has been a method of blending spherical powder or plate-like powder or using a large amount of low-viscosity silicone oil. In addition, as a method of improving the persistence of the makeup, there is a method in which solid oil, a semi-solid oil (paste oil), and an oil-soluble resin are blended to increase the adhesion to the skin, and a surface powder treated with a fluorine compound is blended. And a method of blending a fluorine-based oil agent to improve the water resistance and oil resistance of the decorative film. Further, as a method of reducing the feeling of burden on the skin of the cosmetic film, a method of increasing the blending amount of the liquid oil to reduce a feeling of dryness, a feeling of dryness, a feeling of stiffness,
There has been a method of reducing the blending amount of solid oil or oil-soluble resin.

[0003]

However, when a large amount of spherical powder or plate-like powder is blended, the decorative film tends to feel powdery and dry. In some cases, the properties deteriorated and the solid strength decreased. Further, when a large amount of silicone oil is blended, the adhesion of the decorative film may be inferior and the durability of the cosmetic may be reduced.
Furthermore, when solid oil, semi-solid oil (paste oil), and oil-soluble resin are blended, the adhesion becomes stronger, the decorative film becomes harder, the skin feels a burden, and it tends to become uneven at the time of application, and the finish becomes thicker. In some cases, the cosmetic film became unnatural. And
Mixing powders that have been surface-treated with a fluorine compound, or compounding a fluorine-based oil, will result in poor compatibility with other oils, reducing the uniformity of the cosmetic film, and the sebum secreted over time. There is a case where the makeup penetrates between the skin and the makeup film and pushes up the makeup film, thereby deteriorating the persistence of the makeup. Further, when the blending amount of the liquid oil is further increased, in the case of a solid powder cosmetic, the cake surface becomes hard when repeatedly used, and a phenomenon (caking phenomenon) that cannot be removed with props may occur. For this reason, there is a need to develop an excellent powder cosmetic that has smooth elongation and spread, is excellent in persistence of makeup, does not have a burden on the skin, and does not cause caking when used in solid powder cosmetics. Longed for.

[0004]

Under such circumstances, the present inventors have conducted intensive studies and as a result, have found that an organopolysiloxane compound having a radical polymerizable group at one end of a molecular chain and an alkyl (meth) compound having 12 to 30 carbon atoms. An acrylic-silicone-based graft copolymer obtained by copolymerizing a radical polymerizable monomer mainly composed of acrylate, a fluorinated oil agent and / or a fluorine-modified silicone oil, and a powder cosmetic containing a powder are described above. Have been found, and the present invention has been completed.
