The invention relates to a process for manufacturing non-oily emollients with a molecular weight below about 600 Dalton, preferably below 550 Dalton, and still more preferably below about 450 Dalton, based on alcohol and fatty acid esters (wax-esters), which consists of the following steps:a) interesterification of the triglycerides contained in a fatty material by a primary alcohol, in the presence of a catalyst;b) elimination of the catalyst;c) distillation of the residual alcohol preferably in the presence of a bleaching agent followed by elimination of the bleaching agent;d1) either frigelisation of the preferably bleached residue such that residual glycerides are at least partially crystallized, followed by elimination of said crystallized residual glycerides,d2) or hydrogenation of the residue, preferably bleached. |
