To provide an oil-in-water emulsion cosmetic composition obtained by using a polyglycerin fatty acid ester as a surfactant, which has high stability against temperature and is excellent in tactile sensation, and a method for producing the same, the present invention provides an oil-in-water emulsion cosmetic composition, wherein the composition comprises 1) a polyglycerin fatty acid ester, as a surfactant, having a hydroxyl value of 450 to 700, a fatty acid residue having 16 to 18 carbon atoms accounting for 50 to 100% by mass of all constituent fatty acid residues, the polymerization degree of glycerin having specific distribution, 2) an oily component, and 3) water.

Oil-in-water emulsion cosmetic composition and method for producing the same

A self emulsification type oily liquid cosmetic composition includes 8 to 30% by mass of the following component A and 50 to 92% by mass of the following component B. Component A: a polyglycerin fatty acid ester having a hydroxyl value of 450 to 700, and a branched fatty acid residue having 16 to 18 carbon atoms and/or a linear unsaturated fatty acid residue having 16 to 18 carbon atoms accounting for 50 to 100% by mass of total constituent fatty acid residues, and in a polyglycerin constituting the polyglycerin fatty acid ester, a total content of a polyglycerin cyclic compound of a dimer and a trimer is from 0 to 3% based on the entire polyglycerin, a total content of a polyglycerin of a undecamer or a higher multimer is from 10 to 30% based on the entire polyglycerin, and each content of a polyglycerin of a tetramer to a decamer is from 4 to 20% based on the entire polyglycerin. Component B: an oily component.
