EMULSION-TYPE EXTERNAL PREPARATIONS FOR SKIN

摘要

The emulsified external skin preparation of the present invention is characterized by comprising a polyglycerol derivative represented by formula (1): wherein, m + 2 represents the average polymerization degree of polyglycerol and 1‰¦m‰¦4; R 1 is a hydrocarbon group having 1 to 4 carbon atoms or a hydrogen atom; AO is an oxyalkylene group having 3 to 4 carbon atoms; and n is the average addition mole number of the oxyalkylene group and 1‰¦m×n‰¦200. In a water-in-oil type external skin preparation, and especially in that containing a polar oil or a silicone oil, emulsion stability is improved. In an oil-in-water type external skin preparation, feeling in use and emulsion stability are improved. Especially, in an oil-in-water type external skin preparation containing hydrophobized powder, powder dispersion stability is improved as well as feeling in use and emulsion stability.
