Description

TECHNICAL FIELD The present invention relates to a water-in-oil emulsified cosmetic containing a large amount of a film-forming agent.

So-called make-up cosmetics have functional effects such as long lasting makeup and prevention of secondary adhesion in addition to the aesthetic effect of making the makeup look more beautiful. As one of the techniques for improving the functional effect, especially the long-lasting effect of makeup, it is known to incorporate various film-forming agents.

For example, Patent Document 1 describes a water-in-oil emulsified cosmetic containing a film-forming silicone resin selected from trimethylsiloxysilicate and acrylic-silicone graft copolymers. The water-in-oil emulsified cosmetic of Patent Document 1 uses a volatile silicone oil, especially a cyclic dimethylpolysiloxane such as octamethylcyclotetrasiloxane or decamethylcyclopentasiloxane, from the viewpoint of compatibility with the film-forming silicone resin. It is

Cyclic dimethylpolysiloxane, so-called cyclic silicone, is excellent in usability and has good compatibility with a wide variety of oils. However, due to its high stability, cyclic silicones usually remain in nature without being decomposed. Therefore, from the viewpoint of environmental problems, investigation of oil content as an alternative to cyclic silicones is an urgent issue.

JP 2006-265213 A

However, simply changing the cyclic silicone to a linear silicone drastically reduces the stability. As a result of intensive studies, the present inventors have found that the combined use of a glycerin derivative can provide stability comparable to that of cyclic silicones, and that a large amount of a coating agent can be blended, leading to the present invention.

The present invention has been made in view of the above problems, and has high stability without using a cyclic silicone, can be formulated with a large amount of a film agent, and has excellent long-lasting and spreadable water-in-oil emulsion makeup. The purpose is to provide
