JP 2010-222317 A JP 2001-122756 A

  However, gel cosmetics have a particular problem that they are sticky when applied (for example, when dried) or after application. Therefore, in addition to a refreshing and light feeling of use, there is no gel-like skin cosmetic that does not become sticky at the time of application or after application, and provides a smooth feel (smooth feeling). .

  On the other hand, the present inventors tried to give a smooth feeling to the gel skin cosmetics by blending powder. However, when powder is blended, it can reduce stickiness and give a feeling of smoothness, but after applying cosmetics to the skin, it may have a powdery finish or a non-lustrous finish. It turned out that the finish as a cosmetic for cosmetics becomes worse. That is, it has been difficult to obtain an excellent gel-like cosmetic for skin that satisfies both the feeling of use and the finish at a high level.

  In addition, gel-like skin cosmetics are also required to give the user a high-class feeling and palatability by giving an opaque white appearance such as cream.

  Accordingly, an object of the present invention is to provide a gel-like skin cosmetic that has a white and opaque appearance, is excellent in a smooth feeling at the time of application and after application, and has an excellent finish with an appropriate gloss after application. It is to provide.

  As a result of intensive studies, the present inventor has blended silicone-treated synthetic phlogopite and a specific powder at a specific ratio, respectively, and further by adding a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer, In addition, the present inventors have found that a gel-like cosmetic for skin having an opaque appearance and excellent in a feeling of smoothness after application and after application and finish after application has been obtained.

  That is, the present invention includes (A) 1.5 to 10% by weight of synthetic phlogopite treated with silicone, (B) nylon powder, polymethyl methacrylate powder, polyurethane powder, crosslinked polystyrene powder, and silicone powder. Provided is a gel skin cosmetic comprising 0.1 to 5% by weight of a powder selected from the group consisting of a body and (C) a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer. .

  It is preferable that the gel skin cosmetic further includes (D) polyethylene glycol having a number average molecular weight of 4000 to 30000.

  The gel-like skin cosmetic of the present invention has a white and opaque appearance by having the above configuration. In addition, a smooth feel is obtained at the time of application to the skin and after application, and the feeling of smoothness is excellent. Moreover, the skin after application has an excellent finish with moderate gloss.

  The gel-like cosmetic for skin of the present invention comprises (A) 1.5 to 10% by weight of synthetic phlogopite treated with silicone, (B) nylon powder, polymethyl methacrylate powder, polyurethane powder, and crosslinked polystyrene powder. And 0.1 to 5% by weight of a powder selected from the group consisting of a body and a silicone powder, and (C) a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer. The gel skin cosmetic of the present invention preferably further comprises (D) a polyethylene glycol having a number average molecular weight of 4000 to 30000. Moreover, it is preferable that the gel-like skin cosmetic of the present invention contains water.

  In the present specification, the “(A) silicone-treated synthetic phlogopite” is referred to as “component (A)”, the “(B) nylon powder, polymethyl methacrylate powder, polyurethane powder, and crosslinked polystyrene. “Powder selected from the group consisting of powder and silicone powder” is “component (B)”, and “(C) carboxyvinyl polymer and / or alkyl-modified carboxyvinyl polymer” is “component (C)”. The “(D) polyethylene glycol having a number average molecular weight of 4000 to 30000” may be referred to as “component (D)”. The “carboxyvinyl polymer and / or alkyl-modified carboxyvinyl polymer” means “one or both of carboxyvinyl polymer and alkyl-modified carboxyvinyl polymer”.

  The gel skin cosmetic of the present invention may contain components other than component (A), component (B), component (C), component (D) and water. In addition, each component used in the gel skin cosmetic of the present invention may be only one kind or two or more kinds.

  The component (A) is a powder obtained by treating the surface of a synthetic phlogopite (synthetic mica) with a silicone compound (preferably, coating treatment). By mix | blending a component (A), the stickiness at the time of use (at the time of application | coating and after application | coating) of the gel-like skin cosmetics of this invention is suppressed, and a smooth feeling improves. Furthermore, after applying the gel-like skin cosmetic of the present invention, it is preferable because an appropriate gloss is imparted to the skin and an excellent finish is obtained. When synthetic phlogopite not subjected to silicone treatment is used in place of component (A), stickiness occurs and a smooth feeling cannot be obtained, which is not preferable. Further, when non-synthetic mica treated with silicone is used, the resulting cosmetic is gray and unfavorable in appearance. Further, when mica titanium treated with silicone is used, it is not preferable because glare becomes stronger and the finish becomes worse after applying the obtained cosmetic.

  Although the average particle diameter of the synthetic phlogopite is not particularly limited, it is preferably 1 to 40 μm, more preferably 2 to 25 μm, from the viewpoint of providing an appropriate gloss with little glare.

  Although it does not specifically limit as a silicone compound used for the silicone process of a component (A), For example, a linear silicone, a cyclic silicone, a crosslinked silicone, a modified silicone, a trimethylsiloxy silicic acid etc. are mentioned. Specifically, linear silicones such as octamethyltrisiloxane, tetradecamethylhexasiloxane, methylpolysiloxane, methylphenylpolysiloxane, highly polymerized methylpolysiloxane, methylhydrogenpolysiloxane; methylcyclopolysiloxane, octamethylcyclo Cyclic silicones such as tetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, and cyclic silicone resin; crosslinked silicones such as crosslinked methylpolysiloxane and crosslinked methylphenylpolysiloxane; polyether-modified silicone, alkyl-modified silicone, amino Modified silicone, polyglycerin modified silicone, higher fatty acid ester modified silicone, phenol modified silicone, one or both end trialkoxy group modification And modified silicone such as organopolysiloxanes. Among them, methyl hydrogen polysiloxane (ingredient name of cosmetics: hydrogen dimethicone, INCI name: HYDROGEN DIMETHICONE) is preferable, and for example, commercially available products such as KF-9901 (trade name, manufactured by Shin-Etsu Chemical Co., Ltd.) are used. You can also. The said silicone compound may use only 1 type and may use 2 or more types.

  Although the quantity of the said silicone compound used for a process is not specifically limited, 0.5-5 weight part is preferable with respect to 100 weight part of synthetic phlogopite. When the amount of the silicone compound is less than 0.5 parts by weight, the hydrophobicity of the component (A) is lowered, and the effect of improving the feeling of dryness by the component (A) may be lowered. Moreover, when it exceeds 5 weight part, it may become disadvantageous from a viewpoint of economical efficiency.

  The method of silicone treatment is not particularly limited, and a normal surface treatment method or the like can be used. For example, a wet method in which a synthetic phlogopite is dispersed in a solvent such as water or an organic solvent in a mechanochemical type mill such as a ball mill or a sand grinder, and then the silicone compound is mixed and the solvent is removed and dried; A dry method in which a synthetic phlogopite and a silicone compound are mixed with a sill mixer or a super mixer and then dried; in a high-speed air stream such as a jet mill (for example, see Japanese Patent Publication No. 06-59379), the synthetic gold Examples include a method in which mica and a silicone compound are brought into contact with each other.

  In addition, only 1 type may be used for a component (A) and 2 or more types may be used. Moreover, a commercial item can also be used for a component (A).

If content of a component (A) is less than 1.5 weight%, the gloss after application | coating will fall and a finish will worsen. Furthermore, the effect of improving the smooth feeling at the time of application and after application cannot be obtained. On the other hand, if it exceeds 10% by weight, the glare after application becomes strong and the finish becomes poor.

  The component (B) is a powder (at least one kind of powder) selected from the group consisting of nylon powder, polymethyl methacrylate powder, polyurethane powder, crosslinked polystyrene powder, and silicone powder. Although these powders are not particularly limited, many of them have hydrophobic and spherical characteristics. Therefore, by blending component (B), the gel-like skin cosmetic of the present invention can be applied and The feeling of smoothness after application is improved. Furthermore, the effect of making the gel-like skin cosmetic of the present invention white and opaque is improved, which is preferable. If talc or silica having relatively high hydrophilicity is used in place of the component (B), stickiness occurs after application and a smooth feeling cannot be obtained, which is not preferable.
