Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
102 words
An aqueous washing composition for washing a surface to deposit thereon substantially water-insoluble particles, comprising an anionic surfactant, the particulate substance and a water-soluble cationic non-cellulosic polymer for enhancing 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, wherein the cationic charge density of the polymer is from 0.0001 to 0.0017; the concentration of the cationic polymer in the washing composition is from 0.0001% to 0.01% by weight; and the concentration of the surfactant in the washing composition is from 0.01% to 5% by weight.
Claim 2
Dependent Claim
102 words
An aqueous washing composition for washing a surface to deposit thereon substantially water-insoluble particles, comprising an anionic surfactant, the particulate substance and a water-soluble cationic non-cellulosic polymer for enhancing 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, wherein the cationic charge density of the polymer is from 0.0001 to 0.0017; the concentration of the cationic polymer in the washing composition is from 0.0001% to 0.01% by weight; and the concentration of the surfactant in the washing composition is from 0.01% to 5% by weight.
