Description

  The present invention relates to an emulsified cosmetic.

  Silicone oil is used as an oil agent in various fields for its safety and the like. It is also frequently used in cosmetics, and in the use of makeup cosmetics, particularly low viscosity silicone oil is widely used due to its excellent extensibility, refreshing feeling and safety.

As such a silicone surfactant, a polyether-modified silicone having a polyoxyalkylene group at the terminal or side chain of siloxane is known (Patent Documents 1 to 5). Further, Patent Document 6 describes a polyether-modified silicone having a branched main chain siloxane structure, and Patent Document 7 describes an ABA (silicone-hydrophilic group-silicone) type copolymer represented by the following formula. Certain polyether modified silicones have been described.

In particular, ABA (silicone-hydrophilic group-silicone) type copolymer is a powder-containing cosmetic and excellent in powder dispersibility. However, conventional silicone surfactants have a problem in that they have poor skin adhesion and stability over time.
