| 摘要 |
The compositions of the present invention relate to improved aqueous or aqueous-alcoholic hair styling compositions comprising a combination of two copolymers. The first copolymer is a copolymer of (a1) acidic vinyl monomers, e.g., acrylic or methacrylic acid, with (a2) hydrophobic nonionic vinyl monomers, e.g., acrylic or methacrylic acid esters, with (a3) a first associative monomer and (a4) at least one other monomer which can be a second associative monomer different from the first associative monomer or a semihydrophobic monomer. The associative monomers having (i) an ethylenically unsaturated end group, (ii) a hydrophilic midsection and (iii) a hydrophobic or semi-hydrophobic end group. The second copolymer is a copolymer of (b1) C<SUB>3 </SUB>to C<SUB>8 </SUB>monoethylenically unsaturated monocarboxylic acid monomers, (b2) acrylic or methacrylic acid alkyl esters, and (b3) acrylic or methacrylic acid hydroxyalkyl esters. Preferred product forms are gels, additionally containing a gel forming agent. The compositions can be used for increasing the humidity resistance, moisture resistance or sweat resistance of a hair style.
