Abstract
Abstract Novel bi-substituted derivatives of glycerol of the formula: CH2-X-R1 HO-CH ANGLE CH2-Y-R2 wherein X and Y, which can be the same or different, are either -O- or -O-C- PARALLEL O where R1 is a branched alkyl radical having from 5 to 8 carbon atoms, with the number of carbon atoms in the branched portion being 1, 2, or 3, and R2 is a linear alkyl radical having from 11 to 18 carbon atoms. These novel derivatives remain liquid at or below 30 DEG C and are particularly useful in cosmetic compositions.
