(I) Per 100 mol%, a) greater than 70 mol% to 99.9 mol% of hydrophobic monomer units derived from stearyl methacrylate (A); And b) from 0.1 mole% to 30 mole% of a monomeric unit (B) derived from at least one monomer of the compound of formula (I) wherein R 1 is a straight or branched chain alkyl comprising 12 to 22 carbon atoms Radicals, R2 is a hydrogen atom or a methyl radical, n is an integer from 0 to 30, and the compound of formula (I) is not stearyl methacrylate). The present invention also relates to a method for producing the copolymer and to using the copolymer as an oily rheology modifier for topical administration of cosmetics, skin preparations or pharmaceutical compositions. |
