risclosed are aqueous hair setting compositions comprising, as the sole hair fixative component, rheology modifying, hair setting, associative polymers (RMHS), which are the polymerization product of a monomer mixture comprising an acidic vinyl monomer; and an associative monomer. The hair setting compositions provide surprisingly good to excellent hair setting efficacy, based on high humidity curl retention. A wide range of rheological characteristics was achieved together with good clarity and aesthetic product properties. Particularly preferred rheology modifying hair setting associative polymers are certain hydrophobically modified alkali-swellable and alkali- soluble associative polymers (ASAP) and HASE polymers disclosed herein. Also disclosed are methods of setting hair using RMHS polymer-containing compositions.

L'invention concerne des compositions de coiffage aqueuse comprenant, en tant que composant fixateur unique, des polymères (RMHS) associatifs de coiffage et de modification rhéologique, qui consiste en un produit de polymérisation d'un mélange de monomères contenant un monomère vinylique acide et un monomère associatif. Les compositions de coiffage offrent une efficacité de coiffage étonnamment bonne à excellente, fondées sur le maintien de boucle d'humidité élevée. Il fournit une large gamme de caractéristiques rhéologiques et d'excellentes propriétés de produit esthétique et pur. Plus particulièrement, ces polymères associatifs de coiffage et de modification rhéologique préférés consistent en des polymères associatifs hydrophobiquement modifiés gonflant aux alcalis et solubles dans ceux-ci (ASAP) et des polymères HASE. L'invention concerne également des procédés de coiffage au moyen des compositions contenant les polymères RMHS.
