摘要

The invention relates to an anionic polyelectrolyte, a linear, branched or crosslinked terpolymer of at least one monomer having a partially- or totally-salified free strong acid function with at least one neutral monomer selected from among N,N-dimethyl acrylamide and 2-hydroxyethyl acrylate, and at least one monomer having formula (I), wherein R1 represents a hydrogen atom, R represents a linear or branched alkyl radical comprising between eight and 16 carbon atoms and n represents a number greater than or equal to one and less than or equal to 10. The invention also relates to the preparation method thereof and to the use of same in cosmetics.
