Abstract
This invention relates to a novel lipid composition for use in cosmetics capable of increasing moisture-keeping ability or barrier function of the stratum corneum, protecting the skin and improving dry or rough skin, and to products which use the same, such as cosmetics and medicaments. Particularly, it relates to a lipid composition which comprises at least one component (A) selected from the group consisting of a 2-acylaminoalkane-1,3-diol and optically active compounds thereof, at least one component (B) selected from the group consisting of a 2-acylaminoalkane-1,3-diol in which at least one of the &agr;-position and &bgr;-position of the acyl group is substituted with hydroxyl group and optically active compounds thereof and at least one component (C) selected from sterols, wherein the components (A), (B) and (C) are mixed at a ratio that constructs a liquid crystal structure, and to products which contain the lipid composition, such as cosmetics and medicaments.
