Abstract The invention concerns a washing composition for washing a surface to deposit thereon substantially water-insoluble particles. The aqueous washing composition of the invention comprises an anionic surfactant, the particulate substance to be deposited and a water-soluble cationic non-cellulosic polymer which enhances the deposition of the particulate substance onto the surface but which cationic polymer does not form in the composition a water-insoluble complex with the anionic surfactant, the cationic charge density of the polymer being from 0.0001 to 0.0017; the concentration of the cationic polymer in the washing composition being from 0.0001% to 0.01% by weight; and the concentration of the surfactant in the washing composition being from 0.01% to 5% by weight.
An aqueous shampooing composition for washing hair to deposit thereon substantially water-insoluble anti-microbial particles, comprising from 0.1% to 5% by weight of an anionic surfactant selected from the group consisting of alkyl sulfate and alkyl ether sulfate, from 0.001% to 1% by weight of anti-microbial particles of zinc pyridinethione and from 0.0001% to 0.01% by weight of a water-soluble cationic non-cellulosic galactomannan gum polymer for enhancing the deposition of the particles onto the hair but which cationic polymer does not form in the composition a water-insoluble complex with the anionic surfactant, wherein the cationic charge density of the polymer is 00.0008.
