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.
本发明涉及使用阴离子性的两性共聚物或阳离子性的两性共聚物,该共聚物可通过自由基共聚反应获得,其中:a1)至少包含一个自由基聚合,α,β-乙烯基不饱和双键和至少一个分子中的阴离子和/或阴离子基团的化合物,a2)至少包含一个自由基聚合,α,β-乙烯基不饱和双键和至少一个分子中的阳离子和/或阳离子基团的化合物,b)至少包含一个自由基聚合的交联剂,该交联剂每个分子中包含至少两个α,β-乙烯基不饱和双键,c)如果需要,存在至少一种包含聚醚基团和/或自由基聚合烯烃不饱和双键的硅氧烷化合物,作为头发化妆品组合物的流变学改性剂。
