Description

Cosmetics {COSMETIC PREPARATION}

The present invention relates to a cosmetic having no stickiness, excellent moisturizing feeling after use, and good stability with time.

Conventionally, as a cosmetic component, there is no oily feeling at all, and silicone oil which improves the persistence of makeup is used a lot. However, silicone oils have been pointed out such as poor skin intimacy and poor moisturizing properties. To solve this problem, various modified silicones such as perfluoroalkyl-modified organopolysiloxane and organopolysiloxane having a polyoxyalkylene group are introduced and applied (for example, Japanese Patent No. 2754108, Japanese Patent Application Laid-Open No. 7-277923, Japanese Patent Laid-Open No. 7-33622, etc.).

However, the effect is not sufficient with the perfluoroalkyl-modified organopolysiloxane, and the organopolysiloxane having a polyoxyalkylene group introduced therein has a problem in stability over time such that the pH decreases due to hydrolysis in the presence of water. These silicone compounds also have poor skin intimacy, and are still not satisfactory in terms of moisturizing properties and stability over time, and new developments are required.

In recent years, polyhydric alcohol-modified silicones have been reported as an emulsion having excellent adhesion to skin, no stickiness, and a fresh feeling (Japanese Patent Laid-Open No. 2002-179798). However, even when this oil agent is used, the function and the property as a cosmetics are not enough, and the provision of more excellent cosmetics is calculated | required.

As a result of repeated consideration of the present invention, the present inventors have found that a combination of a specific polyhydric alcohol-modified silicone compound, a phospholipid, and water is used to obtain a cosmetic that has no stickiness, is excellent in moist moisture after use, and has good stability over time. It has been found that the present invention can be completed.
