The present invention relates to a fatty acid ester of an etherified polyhydric alcohol represented by the following general formula (1), a production process thereof, a cosmetic composition comprising this compound, and a production process of an etherified polyhydric alcohol via the ester. G(A).sub.x (B).sub.y (1) (G: a residue formed by removing H atoms of all the OH groups of a polyhydric alcohol having at least three OH groups, A: --CH.sub.2 CH(OH)R or --CHRCH.sub.2 OH, R.sup.1 : R.sup.1a or --CH.sub.2 OR.sup.1a (R.sup.1a : C.sub.1 -C.sub.36 alkyl or alkenyl group), B: H or C.sub.1 -C.sub.11 acyl group, x+y: the number of the OH groups of G, x.gtoreq.1, y.gtoreq.1, and at least one of y groups B: alkanoyl group). The compound (1) is not only useful as an intermediate for the production of an etherified polyhydric alcohol, but also excellent per se in the performance as a cosmetic base, emulsifier, lubricant, oily component and the like.
本发明涉及以下一般式(1)所表示的醚化多羟醇的脂肪酸酯、其生产方法、包含该化合物的化妆品组合物以及通过酯化制备醚化多羟醇的生产方法。G(A).sub.x (B).sub.y (1)(其中,G:由至少具有三个羟基的多羟醇的所有羟基的氢原子去除而形成的残基,A:--CH.sub.2 CH(OH)R或--CHRCH.sub.2 OH,R.sup.1:R.sup.1a或--CH.sub.2 OR.sup.1a(R.sup.1a:C.sub.1 -C.sub.36烷基或烯基),B:H或C.sub.1 -C.sub.11酰基,x+y:G的羟基数,x≥1,y≥1,并且至少有一个y个B基团:烷酰基)。该化合物(1)不仅可作为制备醚化多羟醇的中间体,而且在化妆品基料、乳化剂、润滑剂、油性成分等方面本身也具有优异性能。
