Abstract
A hair care composition is disclosed comprising a copolymer, an ethoxylated alkyl sulfate anionic surfactant having a formula RO(CHCHO)nSOM, wherein R is an alkyl or alkenyl having from 8 to 18 carbon atoms; M is a solubilising cation comprising sodium, potassium, ammonium or mixtures thereof; the degree of ethoxylation n is 2, and from 0.01 to 5% by weight of a zinc-based anti-dandruff agent; wherein the copolymer comprises: a cationic vinyl monomer A represented by the formula: CH═C(R)—CO—NH—(CH)NRRRX, wherein Ris a hydrogen atom or a methyl group, each of Rto Ris independently a Calkyl group, preferably a Calkyl group, Xis independently fluoride, chloride, bromide or iodide anion, preferably chloride, and d is an integer of from 1 to 10; a cationic vinyl monomer B represented by the formula: CH═C(R)—CO(O)—(CH)NRRRY, wherein Ris a hydrogen atom or a methyl group, each of Rto Ris independently a Calkyl group, preferably a Calkyl group, Yis independently fluoride, chloride, bromide or iodide anion, preferably chloride, and e is an integer of from 1 to 10; a vinyl monomer C represented by the formula: CH═C(R)—CO—NRR, wherein Ris a hydrogen atom or methyl group, each of Rand Ris independently a hydrogen atom or a Calkyl group, provided that the sum of carbon numbers of Rand Ris from 1 to 4; and wherein the content of monomer A is from 1 to 44 mol % based on the total monomer content of the copolymer, the content of monomer B is from 1 to 44 mol %, and the content of monomer C is from 20 to 75 mol % based on the total monomer content of the copolymer.
