PROBLEM TO BE SOLVED: To provide an emulsified composition-containing ester based compound with a high product value, which significantly suppresses a temporal decomposition or content reduction.SOLUTION: The inventors found out that when obtaining a water-in-oil emulsified composition in combination with a lipophilic surfactant with an HLB of 7.0 or less, the temporal content reduction of an ester based compound is suppressed. As the ester-based compound of the invention, an ester-based steroid compound, ester-based vitamin A derivative, ester-based vitamin C derivative, cinnamic acid derivative, benzoyl derivative, nicotinic acid derivative, or aminobenzoic acid alkyl ester are included. This emulsified composition is useful as emulsified compositions, such as pharmaceuticals, quasi drugs, and cosmetics.SELECTED DRAWING: None |
