New thickening polymer reducing the stickiness of glycerine-based cosmetic formulas

A linear, branched or crosslinked anionic polyelectrolyte derived from the polymerization, per 100 mol %:

• a) of a mole proportion of greater than or equal to 50% and less than or equal to 99% of monomer units derived from a monomer comprising a free, partially salified or totally salified strong acid function;
• b) of a mole proportion of greater than or equal to 1% and less than or equal to 50% of a monomer of formula (I):
• CH2═CH(R1)—(C(═O)—O—(CH2)n—CF3 (I),
• which formula (I) the radical R1 represents a hydrogen atom or a methyl radical, and n represents an integer equal to 1, 2 or 3;
• c) optionally, of a mole proportion of greater than 0% and less than or equal to 5 mol %, of monomer units derived from at least one monomer of formula (II):
• R2—C(═O)—O—[(CH2—CH(R4)—O]n—R3 (II),
• in which formula (II) m represents a number greater than or equal to 0 and less than or equal to 50, R2 represents an unsaturated aliphatic monovalent radical comprising from 2 to 4 carbon atoms, R4 represents a hydrogen atom, a methyl radical or an ethyl radical and R3 represents a linear or branched, saturated or unsaturated hydrocarbon-based aliphatic radical comprising from 8 to 30 carbon atoms, and
• d) optionally of a mole proportion of greater than 0% and less than or equal to 5% of at least one diethylenic or polyethylenic crosslinking monomer.
