-hybridized nitrogen atom with a dialkyl sulfate or trialkyl phosphate and subjecting the resulting ammonium compound to an anion exchange.
Ampholytic copolymers which contain a molar excess of anionogenic and/or anionic groups, polyelectrolyte complexes which contain such an ampholytic copolymer, cosmetic and pharmaceutical compositions which contain at least one such copolymer or polyelectrolyte complex and the use of these copolymers and polyelectrolyte complexes are described.

The present invention relates to the use of an anionically ampholytic or cationically ampholytic copolymer which which is obtainable by free-radical copolymerization of
a1) at least one compound with a free-radically polymerizable, α,β-ethylenically unsaturated double bond and at least one anionogenic and/or anionic group per molecule,
a2) at least one compound with a free-radically polymerizable, α,β-ethylenically unsaturated double bond and at least one cationogenic and/or cationic group per molecule,
b) at least one free-radically polymerizable crosslinking compound which comprises at least two α,β-ethylenically unsaturated double bonds per molecule,
c) if appropriate in the presence of at least one silicone compound comprising a polyether group and/or a free-radically polymerizable olefinically unsaturated double bond,
as rheology modifier for hair cosmetic compositions.
The present invention relates to a cosmetic process for treating keratin materials, which can give them, especially in a long-lasting and reversible manner, interesting cosmetic properties; this process comprising the application to said materials:
in a first stage, of a cosmetic composition comprising at least one graftable species, comprising at least one unit of formula (Ia):
and in a second stage, of a cosmetic composition comprising at least one cosmetic active agent bearing at least one unit of formula (Ia):
The invention also relates to a kit comprising said compositions.
