Abstract

A liquid cleaning composition comprises solid particles dispersed in a liquid solvent phase, which phase comprises a liquid polyalkoxylated material, the composition further comprising polyvinylpyrrolidone, or a derivative thereof, having a viscosity average molecular weight of less than 30,000 and being dissolved in said liquid solvent phase. The polymer inhibits network formation which would otherwise lead to viscosity increase on storage.
