An N-long-chain acyl neutral amino acid ester containing a straight-chain or branched-chain, saturated or unsaturated acyl group having from 6 to 22 carbon atoms, where the hydrocarbon group of the alcohol constituting the ester is a straight-chain or branched-chain, saturated or unsaturated hydrocarbon group having from 1 to 10 carbon atoms disclosed herein is an oily material suitable for cosmetic compositions, which provide an excellent feeling upon use and also an excellent hair conditioning effect to a cosmetic composition containing the same. An ultraviolet ray-absorbing composition containing the N-long-chain acyl neutral amino acid ester or/and an N-long-chain acyl acidic amino acid diester is provided, which also has excellent feel. An inorganic pigment composition containing the N-long-chain acyl neutral amino acid ester or/and the above-mentioned N-long-chain acyl acidic amino acid diester is also provided, which has excellent dispersion (stability) of the inorganic pigment, is less irritating to the skin, has excellent feel upon use and is not sticky.
本文披露了一种含有N-长链酰基的中性氨基酸酯,其中酰基为直链或支链、饱和或不饱和,含有6至22个碳原子,构成酯的醇的烃基为直链或支链、饱和或不饱和,含有1至10个碳原子。该油质材料适用于化妆品配方,使用时提供良好的感觉,同时对含有该材料的化妆品具有出色的发质调理效果。本文还提供了一种含有N-长链酰基中性氨基酸酯和/或N-长链酰基酸性氨基酸二酯的紫外线吸收配方,具有出色的感觉。同时提供了一种含有N-长链酰基中性氨基酸酯和/或上述N-长链酰基酸性氨基酸二酯的无机颜料配方,其具有优异的无机颜料分散(稳定性),对皮肤刺激较小,使用时感觉良好且不粘。
