<p>The present invention relates to a leave-on hair care composition comprising: (i) from about 0.1 % to about 10 %, by weight, of a cationic cross-linked polymeric conditioning agent comprising the monomer units (A)m (B)n (C)p and a cross-linking agent wherein: (A) is a dialkylaminoalkyl acrylate monomer or a quaternary ammonium or acid addition salt thereof; (B) is a dialkylaminoalkyl methacrylate monomer or a quaternary ammonium or acid addition salt thereof; (C) is a nonionic monomer polymerizable with (A) or (B); m, n, and p are independently zero or greater, but at least one of m or n is one or greater; (ii) from about 0.1 % to about 10 %, by weight, of a salt; and (iii) from about 60 % to about 99.8 %, by weight, of a polar solvent; wherein the weight ratio of said cationic cross-linked polymeric conditioning agent to said salt is from about 1:25 to about 25:1; wherein the viscosity of the composition is from about 10 cP to about 500 cP as measured using a Brookfield Viscometer, Spindel #41, at 25 °C, at 10 RPM for three minutes.</p> |
