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

摘要

The present invention is excellent in storage stability of tocopherol glycine to prevent such deterioration occurs in the formulation of viscosity retention provides an emulsified skin external preparation containing an ester derivative. Emulsified skin external preparation is 0.03 to 25 mass% and a tocopherol glycine ester derivative represented by the general formula (1), of the present invention, glycerin mono-fatty acid esters, polyglycerol fatty acid ester and dextrin fatty acid ester at least one fatty acid ester selected from the group consisting of 0.05 should contain about 25 wt% ; & . Formula 1 & ; wherein, R ¹ and R ² , each represent a hydrogen atom or a lower alkyl group but, at the same time there may be a hydrogen atom, R ³ , R ⁴ and R ⁵ are each represents a hydrogen atom or a methyl group.
