Abstract:
1. A method for producing an oil-in-water emulsion cosmetic composition, wherein the oil-in-water emulsion cosmetic composition comprises: a component A: a polyglycerin fatty acid ester having a hydroxyl value of 450 to 700, a atty acid residue having 16 to 18 carbon atoms accounting for 50 to 100% by mass of all constituent fatty acid residues, the total content of a dimer and a trimer of a cyclic polyglycerin being from 0 to 3% by mass, the total content of an undecamer of polyglycerin being from 10 to 30% by mass, and the each content of a tetramer to a decamer of polyglycerin being from 4 to 20% by mass, based on 100% by mass of polyglycerin constituting the polyglycerin fatty acid ester, a component B: a hydrocarbon oil and/or ester oil, and a component C: water, wherein the amount of the component A is from 0.01% to 15% by mass, the amount of the component B is from 0.01% to 50% by mass, and the amount of the component C is from 30% to 95% by mass, wherein the method comprises the step of adding an oil phase containing the component A and the component B to an aqueous phase containing a component C, and emulsifying the two phases.
