Abstract
Compositions particularly suitable for the cleaning of carpets comprise: a peroxygen bleach; an alcohol having the formula R--OH wherein R is linear or branched, saturated or unsaturated hydrocarbon chain of 1 to 4 carbon atoms and a second solvent selected from the group consisting of a hydrophilic solvent comprising one or more ether groups and having a solubility in water higher than 10 ml per 100 ml at 25.degree. C.; a polyol hydrophilic solvent having a solubility in water higher than 10 ml per 100 ml at 25.degree. C.; a hydrophobic solvent having a solubility in water lower than 10 ml per 100 ml at 25.degree. C.; and mixtures thereof; at a weight ratio of said alcohol to said second solvent of 1:10 to 1:1.1. The compositions are particularly suitable for the cleaning of carpets, resulting in improved overall stain removal performance, especially on particulate stains, greasy/oily stains, bleachable stains, and/or enzymatic stains.
