Patent ID: 7438767

Claim:
A liquid composition which in use is applied to a surface and dries to leave a residue, wherein the composition comprises in admixture: (1) particles of a material selected from: a photocatalytic material selected from titania and peroxo modified titania providing 0.01% wt to 5% wt of the composition; and, a photocatalytic material precursor, the photocatalytic material produced from said precursor providing 0.01% wt to 5% wt of the composition wherein said photocatalytic material produced from said precursor is titania or peroxo modified titania; (2) a sensitiser which acts to absorb at one of visible, ultra violet arid infra-red radiation and enhance the photocatalytic action of the photocatalytic material, the sensitiser providing 0.00001% wt. to 1% wt of the composition; and (3) (i) from 0.01% wt. to 65% wt. of the composition of a monohydric alcohol having from 1 to 8 carbon atoms; and (ii) 0.001% wt. to 5% wt. of the composition of a polyhydric alcohol having 2-8 carbon atoms and 2-4 hydroxyl groups wherein the composition necessarily comprises a trihydric linear alcohol having 3-6 carbon atoms (4) 0.005% wt. to 1% wt. of the composition of a film-forming polymer (5) 0.05% wt. to 80% wt. of at least one surfactant selected from the group consisting of cationic surfactants, nonionic surfactants and amphoteric surfactants, wherein, when applied to a hard surface the composition provides a low streaking appearance.
