EMULSIFIED SKIN EXTERNAL PREPARATION AND METHOD FOR STABILIZING THE SKIN EXTERNAL PREPARATION

摘要

An emulsified skin external preparation containing a tocopherol glycinate derivative has excellent storage stability without viscosity reduction during storage. The emulsified skin external preparation includes 0.03 to 25% by mass of a tocopherol glycinate derivative, and 0.05 to 25% by mass of at least one fatty acid ester selected from the group consisting of glycerin mono fatty acid ester, polyglycerin fatty acid ester and dextrin fatty acid ester, the tocopherol glycinate derivative being represented by Formula (1): . . . (1) wherein R1 and R2 are each a lower alkyl group or a hydrogen atom and cannot be hydrogen atoms at the same time, and R3, R4 and R5 are each a hydrogen atom or a methyl group.
