Description

  The present invention relates to an oily cosmetic material having high glossiness.

  There are many cosmetics that require a glossy feeling when applied to the skin or the like. For example, in lip cosmetics such as lipsticks, it is also required as an important effect that the makeup film made up has a glossy feeling. This is demanded not only by cosmetics for the purpose of makeup having a glossy feeling like lip gloss but also by fashion, taste, and the like. In addition, in hair cosmetics such as mascara, in addition to functional effects such as making mascara's original wrinkles look darker and longer like mascara, it is also required to give the wrinkles a glossy feeling. It is done. Thus, it has become an important research subject for cosmetic engineers to develop cosmetics that impart a glossy feeling to the cosmetic film of lip cosmetics and hair cosmetics.

  Conventionally, as a method for imparting gloss to a cosmetic film of cosmetics, it is known to add an oil component having a large refractive index such as phenyl group-containing organopolysiloxane having a phenyl group in the molecule or polybutene to cosmetics. (Refer to Patent Documents 1 and 2), but sufficient gloss for cosmetics containing ingredients to be blended to satisfy usability other than gloss (gloss), feeling of use, long-lasting makeup, etc. At present, the feeling is not obtained. Therefore, for example, a technique for solving the problem by using in combination with other gloss (gloss) imparting components can be seen, but it is not always sufficient (see Patent Document 3). Furthermore, blending powder as a coloring material in cosmetics erases the gloss (gloss), and blending of powder is a negative factor for gloss (gloss). It is also required that the coloring material has a sufficient gloss (luster) feeling even when blended, and that the coloring characteristics of the blended coloring material are sufficiently obtained.

When applied to an application object such as skin such as skin, hair such as wrinkles, the composition containing the oil components (B) and (C) adheres to the application object together with volatilization of the volatile oil. Compared to oil-based cosmetics, it has an excellent high gloss (lustrous) cosmetic film. When blended with coloring materials, it has a high gloss (shiny) and highly colorable cosmetic film, and has a feeling of use and high makeup durability. And found that the above problems can be solved. The has been completed.

That is, the first invention includes the following (A) to (C);

Here, the oil component (C) is a highly polar oil component, and has a strong affinity with skin, hair, etc., and adheres to the skin, hair, etc., while (B) oil component is compatible with (C) oil component. Since it is not soluble, it is considered that it is separated from the oil (C) and located on the surface side. As a result, the applied cosmetic (B) has an oil component located on the surface side, so that it is not sticky and has a glossy (smooth) film, and the (C) oil component on the skin, hair, etc. side It is considered that the adhesion to skin, hair, etc. is enhanced and the makeup persistence is excellent.
