Abstract: Shelf stable, hydrogen peroxide containing carpet cleaning and treatment compositions provide good cleaning efficacy particularly with oxidazable stains, and impart oil repellency properties to treated carpet fibers.
Abstract: Isotropic liquid detergent composition comprises specific soil antiredeposition polymers containing a hydrophilic backbone and monomer with hydrophobic side chains. When the molar ratio of the number hydrophilic groups to number of hydrophobic groups on said polymers is below certain critical levels, it has been unexpectedly found that the stability (i.e., clarity) of the composition remarkably increases. The solubility of the polymer is further dependent on the type and amount (minimum required) of hydrotrope; surfactant type and levels; and minimum electrolyte levels.

Abstract: Isotropic liquid detergent composition comprises specific soil antiredeposition polymers containing a hydrophilic backbone and hydrophobic side chain; and aliphatic hydrocarbon oils. When the molar ratio of hydrophilic groups of the backbone to number of hydrophobic groups attached to the backbone is below certain critical levels; and aliphatic hydrocarbon oil of defined molecular weight (MW) range are incorporated in the formulation; it has been unexpectedly found that the stability (i.e., clarity) of the composition remarkably increases in such oil containing compositions.
