Description

Makeup cosmetic composition

Disclosed herein is a makeup cosmetic composition that uses a non-volatile solvent to effect film forming effects.

Most of the makeup cosmetic compositions applied to the skin often have a cosmetic composition that is smudged or erased when there is external contact with the skin, and furthermore, the skin tends to clump or clump as time passes. In order to prevent such inconvenience and improve the durability and adhesion, conventional film formers have been used to improve the appearance of make-up cosmetic compositions, especially water-in-oil type cosmetic compositions.

In general, film forming agents are formed by blowing volatile solvents. In this case, evaporation of the volatile solvent causes drying and shrinking of the contents, resulting in lowering of formulation stability and storage stability, and the use of volatile solvents There is a problem that occurs. In particular, unlike a liquid makeup cosmetic composition containing a large amount of oil and moisture, in the case of a dough-like makeup cosmetic composition having a form such as jelly, clay or paste, the content is easily exposed to the air, It is difficult to apply a film forming agent. In addition, when only a nonvolatile solvent is used to increase the stability, the film forming effect of the film-forming agent is not exhibited, and thus there is a problem that it is difficult to realize the sustaining force and the adhesion force.

In Comparative Example 4 in which the oil-absorbing powder content was low, the oil- Could know. In the case of Example 2 containing polymethylsilsesquioxane as the oil-absorbing powder, it was confirmed that it had excellent formulation stability compared to Comparative Example 5 in which kneaded without oil and oil were separated to lower the stability of the formulation. In Comparative Example 5, when the polymethylmethacrylate was used as the oil-absorbing powder, the formulation stability was lowered, and it was confirmed that the type of the oil-absorbing powder affects the formulation stability.
