Abstract

PURPOSE:To provide a cosmetic base composed of a long-chain unsaturated fatty acid ester having specific ranges of carbon number and degree of unsaturation, synthesizable at a low cost from a specific fatty acid and an aliphatic alcohol, and exhibiting excellent physical properties and stability comparable to natural HOHOBA oil. CONSTITUTION:The objective cosmetic base is composed of an aliphatic ester which is liquid or waxy at room temperature and storable for a long period without deterioration e.g. by oxidation, etc., consisting of an aliphatic ester having 38-46 carbon atoms on an average and 0.5-2.1 C-C double bonds on an average, and derived from (A) a 18-24C saturated or unsaturated higher fatty acid containing <=5% of highly unsaturated material having two or more C-C double bonds and (B) 18-24C saturated or unsaturated aliphatic alcohol. The ester can be synthesized by the esterification reaction of a specific fatty acid derived from natural oils and fats with an aliphatic alcohol, or by the ester exchange reaction of the lower ester thereof.

This was subjected to unsaturation-preserving selective catalytic reduction alcoholization t-fT. At this time, the conditions under which the conversion rate of ester to alcohol was approximately 50% were cured. An alkali was added to the mixture containing this alcoholic unreacted methyl ester to carry out a transesterification reaction to obtain an unsaturated ester. This was deodorized with reduced pressure steam and decolorized using activated clay to give a glossy finish and used as a sample.
