PROBLEM TO BE SOLVED: To provide emulsion compositions for cosmetics containing a fatty acid-derived lactone compound that allows a fatty acid-derived lactone compound to be homogeneously contained, in a cosmetic, particularly in also an aqueous cosmetic, as the fatty acid-derived lactone compound has been difficult to be homogeneously contained in an aqueous cosmetic because it is a solid oil at normal temperature, the emulsion compositions preventing the precipitation and separation of the fatty acid-derived lactone compound over time and having good transparent properties and excellent temporal stability, to provide production methods thereof, and to provide cosmetics containing the emulsion composition for cosmetics.SOLUTION: An emulsion composition for cosmetics containing a fatty acid-derived lactone compound contains a lactone compound, hydrocarbon oil, fatty-acid sorbitan and polyoxyethylene alkyl ether that are nonionic surfactants, lauryl hydroxy sulfobetaine that is an amphoteric ionic surfactant and water, as an essential ingredient.SELECTED DRAWING: Figure 1 |
