Abstract:
A composition suitable for cleaning carpet comprising:(a) a peroxygen bleach;(b) an alcohol having the formula R--OH wherein R is a linear or branched, saturated or unsaturated hydrocarbon chain of 1 to 4 carbon atoms; and(c) a second solvent selected from the group consisting of:(i) 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.; wherein said hydrophilic solvent is selected from the group consisting of butoxypropanol, propoxy ethyl acetate, ethanol-2-butoxy phosphate, 2-(hexyloxy)ethanol, 2-ethoxy ethanol, 2-butoxyethanol, n-butoxypropanol, butyl triglycol ether, butyl diglycol ether, 2-(2-alkoxyethoxy)ethanol, 2-(2-alkoxyethoxy)propanol, 2-(2-alkoxyethoxy)butanol, and mixtures thereof;(ii) a polyol hydrophilic solvent having a solubility in water higher than 10 ml per 100 ml at 25.degree. C.; wherein said polyol hydrophilic solvent is selected from the group consisting of 2-ethyl-1,3-hexanediol, 2,2,4-trimethyl-1,3-pentanediol, methyl-2,4 pentanediol, and mixture thereof;(iii) a hydrophobic solvent having a solubility in water lower than 10 ml per 100 ml at 25.degree. C.; wherein said hydrophobic solvent is benzyl alcohol; and(iv) mixtures thereof,wherein said composition has a weight ratio of said alcohol to said second solvent of 1:10 to 1:1.1 and has a pH of from 1 to 6.
