Alkaline liquid hard-surface cleaning compositions comprising N-vinylpyrrolidone copolymer

Abstract

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.
