Abstract:
An emollient composition is described which comprises: partially saturated wax esters comprising: IV. R -COO-CH2 and/or V. R -COO-CH2-R , at least 10 % by weight of alkyl esters comprising: VI. R -COO-R and/or VII. R -COO-R and at least 10 % by weight of fatty alcohols comprising: VIII. R CH2-OH and/or IX. R CH2-OH wherein R comprises an alkyl or other aliphatic group, such as CnH2n+1, wherein n=1 to 12, R comprises CH3-(CH2)7-CH=CH-CH2-(CH2)x-, and R comprises CH3-(CH2)y wherein x is 6, 8, 10 and/or 12 and y is 16, 18, 20 and/or 22. A process for producing the emollient comprises the steps of: a) providing a composition comprising jojoba oil and/or hydrogenated jojoba oil, b) adding an alcohol, e.g., having from 1 to 12 carbon atoms, to said composition, c) effecting alcoholysis on said jojoba oil mixed with said alcohol to produce an emollient, and d) effecting an interesterification of residual wax esters.
