Abstract
To provide a novel method for stabilizing pseudo-ceramides. [Solution] The following components (A), (B), and (C): (A) Phospholipids, (B) Pseudoceramides represented by general formula (1) TIFF2026115394000011.tif35170 (In the formula, R 1 X represents a linear, branched, or cyclic saturated or unsaturated hydrocarbon group or hydrogen atom having 10 to 22 carbon atoms; X 1 R represents a hydrogen atom, an acetyl group, or a glyceryl group; 2 R represents a linear, branched, or cyclic saturated or unsaturated hydrocarbon group having 5 to 22 carbon atoms, which may be substituted with a hydroxyl group or an amino group, or a linear or branched saturated or unsaturated fatty acid having 8 to 22 carbon atoms, which may be substituted with a hydroxyl group, esterified to the ω-terminus of the hydrocarbon group; 3 (C) Water is a topical skin preparation containing (C) a hydrogen atom or an alkyl group having 1 to 30 carbon atoms, which may be substituted with a hydroxyl group, a hydroxyalkoxy group, an alkoxy group, or an acetoxy group.
