Abstract
A method for enhancing the performance of hair fixative resins in hair styling compositions by using selected polymers having certain compositions is disclosed. In particular, the present invention involves a method of improving the stiffness performance of hair fixative resins by using polymers containing 5-95% (C,-C,)alkyl (meth)acrylate, 0-70% hydroxyalkyl (meth)acrylate, 0-50% monocarboxylic acid monomer and 1-25% dicarboxylic acid monomer. The selected polymers are particularly useful in aqueous hair styling compositions containing low (80% or less) volatile organic compound (VOC) concentrations.
