Title:
OIL-IN-WATER COSMETIC
Document Type and Number:
WIPO Patent Application WO/2010/064678
Kind Code:
A1
Abstract:
Provided is an oil-in-water cosmetic having superior emulsion stability. The oil-in-water cosmetic comprises (a) oil droplets formed from an emulsified oily component, (b) vesicle particles for stabilizing the oil droplets, and (c) an aqueous phase containing water and a C1-4 monohydric aliphatic alcohol. Preferably the vesicle particles are formed from an amphiphilic substance that spontaneously forms vesicle particles, and are localized to the oil droplet surface. The amphiphilic substance is a polyoxyethylene-hydrogenated castor oil derivative represented by general formula (1) and preferably the average number of ethylene oxide moles added (E) is 10 to 20. (In general formula (1), E=L+M+N+X+Y+Z.)
