PROBLEM TO BE SOLVED: To obtain the subject composition having an excellent O/W type microemulsifying ability even under acidic conditions, excellent in flavor and useful for a food and drink, etc., by composing the composition of a constituent fatty acid which is a prescribed unsaturated fatty acid and providing a prescribed cloud point and a prescribed content of a fatty acid metal salt thereto. SOLUTION: This composition comprises a constituent fatty acid which is a 12-22C unsaturated fatty acid and has 65-90 deg.C cloud point of a 1 wt.% solution in an 8 wt.% aqueous solution of Na2SO4, <=0.2 wt.%, preferably <=0.05 wt.% content of a fatty acid alkali metal salt. Further, >=70% of the constituent fatty acid is preferably oleic acid. The polyglycerol fattyacid ester composition is preferably contained to prepare an emulsified composition in which an oil- soluble perfume, an oil-soluble coloring matter, an antioxidant or a functional fatty acid is emulsified. |
