Abstract:
1. An anti-dandruff composition comprising, in an aqueous medium: (a) from about 0.2 to about 2% by weight of at least one anti-dandruff agent comprising zinc pyrithione; (b) from about 0.1 to about 0.5% by weight of at least one viscosity modifying agent chosen from carbomer; (c) from about 0.1 to about 1% by weight of at least one acrylic-based polymeric compound different from (b) chosen from acrylates copolymer, acrylates/beheneth-25 methacrylate copolymer, acrylates/steareth-20 methacrylate copolymer and mixtures thereof; (d) from about 1 to about 10% by weight of two surfactants comprising: (i) (C8-20 alkyl) amido(C6-8 alkyl) betaines and (ii) (C8-20) alkylbetaines wherein the weight ratio of (i) to (ii) in the composition is at about 2:1; (e) from about 0.025 to about 1% by weight of at least one conditioning agent chosen from cationic polymers and ampholytic polymers; and (f) at least one surfactant chosen from anionic surfactants other than sulfate-containing anionic surfactants, nonionic surfactants, amphoteric or zwitterionic surfactants different from the two surfactants in (d), and cationic surfactants; all weights being relative to the total weight of the composition; wherein the weight ratio of (b) to (c) in the composition is at about 1:1; and wherein the composition is free of sulfate-containing anionic surfactants.
