Abstract
A multicomponent homogeneous polymer of (a) from about 30 to about 90 wt. % of a N-vinyl lactam, (b) from about 5 to about 30 wt. % of a quaternized and/or non-quaternized aminoalkylacrylic -ester and/or -amide, (c) from about 0.5 to about 30 wt. % of an unsaturated monomer selected from the group consisting of an acrylic ester or amide having a C.sub.4 to C.sub.22 alkyl group, a C.sub.4 to C.sub.22 .alpha.-olefin, a C.sub.4 to C.sub.22 vinyl ether (VE) and a vinyl ester of a C.sub.2 to C.sub.22 carboxylic acid and (d) from about 1 to about 30 wt. % of an unsubstituted acrylic or methacrylic acid and/or an unsubstituted amide of said acrylic or methacrylic acid and optionally, (e) up to 20 wt. % of a mono- or di-functional polysiloxane; all monomers combined to form a 100% polymer composition of randomly distributed monomers for use in personal care formulations, particularly as a hair fixative where the clear, colorless and conditioning film forming properties of the polymer produces a silky, lustrous appearance to the hair and long lasting styling hold.
