Abstract

A fatty composition for use in producing cosmetic compositions comprising a mixture of at least one cosmetic fatty body and at least one non-toxic copolymer of the formula: ##EQU1## wherein R.sub.1 represents a saturated hydrocarbon chain, linear or branched, having from 1-19 carbon atoms; R.sub.2 represents a member selected from the group consisting of A. ##EQU2## wherein R.sub.4 has the same meaning as R.sub.1 but is different from R.sub.1 in the same copolymer, B. --CH.sub.2 --R.sub.5, wherein R.sub.5 represents a saturated hydrocarbon chain, linear or branched, having from 5-25 carbon atoms, C. --O--R.sub.6, wherein R.sub.6 is a saturated hydrocarbon chain having from 2 to 18 carbon atoms, and D. ##EQU3## wherein R.sub.7 is a saturated hydrocarbon chain, linear or branched, having from 1-19 carbon atoms, and R.sub.3 represents hydrogen when R.sub.2 represents (a), (b), or (c) or R.sub.3 represents methyl when R.sub.2 represents (d). The copolymer must contain at least 15 weight percent of at least one monomer of unit Ia or of unit Ib in which the saturated hydrocarbon chain, linear or branched, has at least 7 carbon atoms. This fatty composition is employed to produce a cosmet…
