    • 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. The washing-away type cosmetic composition according to the present invention has an emulsion-like or pearl-lustrous appearance and is mild to the skin owing to reduced adsorption, to the skin, of the surfactant contained in the composition.
    • 在本发明中描述的是一种分散体,其包含作为分散质的(a)5至40重量% 在其分子中含有至少一个羟基和酰胺基团的两性脂质的百分比,和(b)2-55重量% %表面活性剂在水性介质中; 一种洗涤型化妆品组合物,其包含该分散体; 和洗涤型化妆品组合物,其包含(A)0.01〜10重量% 在其分子中含有至少一个羟基和酰胺基并且具有不低于30℃的熔点和(B)5-95重量%的两性脂质的百分比。 %的表面活性剂。 根据本发明的分散体可用作洗涤型化妆品组合物的组分,其具有乳状液或珍珠岩外观和低皮肤刺激性。 根据本发明的洗衣型化妆品组合物具有乳状或珍珠色的外观,并且由于组合物中包含的表面活性剂对皮肤的吸附减少,对皮肤温和。
