R7060 ABSTRACT The invention provides a diester of the formula CH3(CH2)5CH(OCOR1)(CH2)10COOR22, in which R1 is a saturated, branched chain hydrocarbon radical having 15 to 21 carbon atoms and R2 is a saturated, branched chain hydrocarbon radical having 8 to 22 carbon atoms. Preferably R1 is a methyl branched chain radical and contains 17 carbon atoms and statistically between 0.5 and 1.0 methyl side-chain per molecule, whereas R2 contains 18 to 22 carbon atoms with a C1-C8 , preferably C1 side-chain. The invention also provides a wax composition comprising a diester defined above optionally together with a hydrocarbon oil (C16-C32 and saturated), a C12-C22 optionally branched chain fatty acid and a monoester derived from a C18 to C22 fatty acid and a C12 to C22 alcohol. Furthermore the invention provides cosmetic preparations containing a wax composition as defined above.
