Abstract
What is described herein are conditioning/styling terpolymers of vinylpyrrolidone (VP), dimethylaminopropyl methacrylamide (DMAPMA) and C9-C24 alkyl dimethylaminopropyl methacrylic acid quaternized monomers (QDMAPMA), in a defined compositional range. Hair and skin care compositions which include these terpolymers exhibit advantageous low tackiness and high humidity resistance.
