Patent

CA 2280860

Liquid hard-surfaces cleaning compositions are disclosed which have a pH above 9 and comprise a copolymer of N-vinylpyrrolidone and an alkylenically unsaturated monomer or a mixture thereof, preferably a quaternized or unquaternized vinylpyrrolidone/dialkylaminoalkyl acrylate or methacrylate copolymer. These compositions provide excellent first time and next time cleaning performance on hard-surfaces soiled by various soils especially grease while exhibiting excellent stability against bacterial contamination.

L'invention concerne des compositions liquides de nettoyage de surfaces dures, dont le pH est supérieur à 9 et qui comprennent un copolymère de N-vinylpyrrolidone, un monomère insaturé sur le plan alkylénique, ou un mélange de ceux-ci, ainsi que, de préférence, un copolymère rendu quaternaire ou non de vinylpyrrolidone/acrylate ou méthacrylate de dialkylaminoalkyle. Ces compositions sont très performantes, dès la première fois, ainsi que les fois suivantes, pour nettoyer des surfaces dures souillées de diverses manières, notamment par des graisses, et elles sont en même temps très stables à l'égard de la contamination bactérienne.
