| abstract |
The invention provides an antimicrobial hair treatment composition for topical application to human hair in the treatment of, for example, dandruff, comprising: (a) at least one surfactant; (b) fine particles of an insoluble particulate metal pyrithione, in which at least about 90 % by weight of the particles have a size of 5 microns or less; and (c) a polymeric, water-soluble cationic deposition aid for the fine particles. The compositions have good mechanical stability, optical properties and anti-dandruff ability. |
