Abstract
The present invention relates to hair conditioning compositions which utilize as a hair conditioning additive a water-soluble polymer in amounts effective to impart hair conditioning properties to the hair conditioning composition, wherein the polymer contains the residue of N-vinyl formamide and the residue of at least one vinyl polymerizable moiety which contains an amine selected from the group consisting of secondary, tertiary and quaternary amines. The conditioning composition also includes one or more ingredients such as conditioning agents, emulsifiers, viscosity modifiers, gelling agents, opacifiers, stabilizers, preservatives, sequestering agents, chellating agents, pearling agents, clarifying agents, fragrances, colorants, and propellants; and water.
