The present invention provides a skin cosmetic containing the following components (A), (B), (C), (D), (E), and (F):

Skin cosmetic

Disclosed herein is a method for producing hydrogel particles including the steps of: solidifying an aqueous solution in which a gel agent forming a non-crosslinked hydrogel is dissolved and which has a gel point of 30&#xb0; C. or more by putting the aqueous solution into a liquid phase having a temperature of equal to or lower than the gel point; and crushing a solidified product obtained by solidifying the aqueous solution in which the gel agent is dissolved.

Method for producing hydrogel particles

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.
