Patent

CA 2317544

The invention concerns hard surface cleaning compositions comprising a nonionic surfactant, a UV absorber and a water soluble anionic polymer. The compositions leave sufficient UV-absorber on the surface after cleaning to provide extended protection of the surface against the damaging effect of UV light. Preferably the compositions also contain a hydrotrope such as an aromatic sulphonate salt and/or an organic solvent such as a glycol ether or a lower aliphatic alcohol.

L'invention concerne des compositions de nettoyage de surfaces dures, comprenant un tensioactif non ionique, un absorbeur U.V. ainsi qu'un polymère anionique hydrausoluble. Ces compositions laissent sur une surface dure, après nettoyage de celle-ci, une quantité d'absorbeurs U.V. suffisante pour doter la surface d'une protection accrue contre les dégradations provoquées par la lumière ultraviolette. De préférence, les compositions contiennent également un hydrotrope, tel qu'un sulfonate aromatique et/ou un solvant organique tel qu'un éther de glycol ou un alcool aliphatique inférieur.
