  • Patent number: 6830754
    Abstract: Described in the present invention are a dispersion which comprises, as a dispersoid, (a) 5 to 40 wt. % of an amphipatic lipid containing, in the molecule thereof, at least one hydroxy and amide group, and (b) 2 to 55 wt. % of a surfactant in an aqueous medium; a washing-away type cosmetic composition comprising the dispersion; and a washing-away type cosmetic composition comprising (A) 0.01 to 10 wt. % of an amphipatic lipid which contains, in the molecule thereof, at least one hydroxy and amide group and having a melting point not less than 30° C. and (B) 5 to 95 wt. % of a surfactant. The dispersion according to the present invention is useful as a component of a washing-away type cosmetic composition having both an emulsion-like or pearl-lustrous appearance and low skin irritation.
