ABSTRACT:
Compositions for hair shaping and/or form retention of hair comprising, in a cosmetically acceptable aqueous medium, at least one film-forming acrylic oligomer, which is soluble or dispersible in the aqueous medium, having a molecular weight, measured by steric exclusion chromatography, of less than or equal to 50,000 and with a glass transition temperature Tg ranging from 0 to 45.degree. C. preferably comprising:
a) from 20 to 45% by weight of at least one residue of a monomer (A) selected from tert-butyl methacrylate, tert-butyl acrylate, and isobutyl methacrylate, relative to the total weight of the at least one film-forming acrylic oligomer;
b) from 5 to 25% by weight of at least one residue of monomer (B) with ethylenic unsaturation comprising at least one carboxylic acid functional group, relative to the total weight of the at least one film-forming acrylic oligomer; and
c) at least one residue of monomer (C) comprising a (C.sub.1 -C.sub.4)alkyl acrylate, in an amount sufficient to produce an oligomer having a Tg temperature ranging from 0 to 45.degree. C., wherein the at least one monomer (C) is not tert-butyl acrylate.
