Description

  The present invention relates to an elastic gel oily cosmetic, and more specifically, 2 to 10% by mass of a partially crosslinked organopolysiloxane polymer, low-viscosity silicone oil, 10 to 40% by mass of powder, inulin fatty acid. The present invention relates to an elastic gel-like oily cosmetic that contains an ester, has a feeling of elasticity, spreads well, is excellent in the uniformity of a cosmetic film, has good stability at rest, and has excellent stability in actual use.

Various formulations and shapes have been developed for cosmetics, such as oily cosmetics, water-based cosmetics, powder cosmetics, water-in-oil cosmetics, and oil-in-water cosmetics, and improvements in usability and usability are being studied. (For example, Patent Document 1).
Recently, an intermediate region between powder cosmetics and oily cosmetics, for example, a region called a funicular region, and among them, excellent portability, light extension and spread, which are the characteristics of powder cosmetics, are not sticky The development of cosmetics that have both a smooth feel, a high emollient effect characteristic of oil-based cosmetics, and high adhesion to the skin, and having the advantages of both (see, for example, Patent Documents 2 and 3). . Furthermore, in the region between powder cosmetics and oily cosmetics, elastic gel-like cosmetics with a unique feeling of use and unique elasticity that cannot be obtained with conventional powder cosmetics and oily cosmetics. Has been studied (see Patent Documents 4, 5, and 6).

JP 2002-275022 A Japanese Patent Laid-Open No. 10-338612 JP 2006-1883 A JP 2005-314369 A International Publication No. 2006/120876 Pamphlet JP 2006-57054 A

However, elastic gel-like oily cosmetics with a resilient feel in a region using a cross-linked organopolysiloxane, solid oil and powder, and a region called the funicular region, have a very narrow prescription area, and one cosmetic When the unit of the amount is increased or the application site is widened, there is a case where a feeling of use with a unique elasticity cannot be obtained or the stationary stability is deteriorated. Also, repeated use may cause sweating, separation, drainage, or kinking, which may deteriorate the stability during actual use.
In addition, cosmetics containing a cross-linked polysiloxane and a large amount of silicone oil are not satisfactory in terms of spreading even though the stability is good. In oily cosmetics, there is a technique for improving compatibility with oil agents other than silicone oil by combining an inulin fatty acid ester and a partially cross-linked polysiloxane polymer as in Patent Document 1, and improving the feeling of use. It has not been studied in the special area of gel, and there is no suggestion for the separation of powder and oil. Further, as in Patent Document 6, there is a technique for obtaining an elastic cosmetic by combining silicone elastic powder and an oil agent. However, a cross-linked organopolysiloxane polymer that obtains elasticity by a gel structure, powder, and inulin fatty acid ester No combined elastic cosmetic has been reported.
For this reason, it feels the elasticity that is an advantage of elastic gel oily cosmetics, has good spread, excellent uniformity of the cosmetic film, excellent standing stability, and excellent stability in actual use. Development was desired.

  Thus, as a result of intensive studies, the present inventors have found that an elastic gel-like oily cosmetic comprising a partially-crosslinked organopolysiloxane, a low-viscosity silicone oil, a powder, and an inulin fatty acid ester in a specific amount solves the above problems. The present invention has been completed.
