摘要

An emulsified cosmetic composition comprising the following ingredients (A), (B), (C), and (D): (A) 0.1% by weight or more and 15% by weight or less of at least one compound selected from the group consisting of a sphingosine or a salt thereof, a pseudo-sphingosine or a salt thereof, and an ionic surfactant, (B) at least one compound selected from the group consisting of a monoglyceryl di-fatty acid ester and a sorbitan di-fatty acid ester, (C) at least one compound selected from the group consisting of a ceramide, an alcohol having 12 to 22 carbon atoms, a monoglyceryl mono-C12 to C22 fatty acid ester, a mono-C12 to C22 alkyl glyceryl ether, and a sorbitan mono-C12 to C22 fatty acid ester, and (D) water, wherein in the ingredients (A), (B), and (C), (1) a weight ratio of (A)/((B)+(C)) is 0.04 or more and 1 or less, (2) a mole fraction of (B)/((B)+(C)) is 0.02 or more and 0.45 or less, and (3) a maximum mole fraction of one compound as a single component in the ingredient (B) and the ingredient (C) is 0.2 or more and 0.8 or less.

1. An emulsified cosmetic composition comprising the following ingredients (A), (B), (C), and (D):
(A) 0.1% by weight or more and 15% by weight or less of at least one compound selected from the group consisting of a sphingosine or a salt thereof, a pseudo-sphingosine or a salt thereof, and an ionic surfactant, (B) at least one compound selected from the group consisting of a monoglyceryl di-fatty acid ester and a sorbitan di-fatty acid ester, (C) at least one compound selected from the group consisting of a ceramide, an alcohol having 12 to 22 carbon atoms, a monoglyceryl mono-C12 to C22 fatty acid ester, a mono-C12 to C22 alkyl glyceryl ether, and a sorbitan mono-C12 to C22 fatty acid ester, except that
(i) ingredient (C) does not comprise both a ceramide and an alcohol having 12 to 22 carbon atoms; and(ii) if ingredient (C) comprises a ceramide, then the composition does not comprise a sterol, and (D) water, wherein, in the ingredients (A), (B), and (C),
(1) a weight ratio of (A)/(B+C) is 0.04 or more and 1 or less,(2) a mole fraction of (B)/(B+C) is 0.02 or more and 0.45 or less, and(3) a maximum mole fraction of one compound as a single ingredient in the ingredient (B) and the ingredient (C) is 0.2 or more and 0.8 or less.
