Polymers for industrial laundry detergents

摘要

The invention discloses detergent compositions containing acrylic acid polymers, including methacrylic acid/ethyl acrylate polymers. In certain embodiments compositions employ an acrylic acid polymer comprising at least 40 wt-% polymerized residues of acrylic monomers, at least 50 wt-% of at least one surfactant, a solvent, at least one water conditioning polymer, and water. The detergent compositions provide increased soil removal and soil suspension when treating textiles, namely through use of industrial laundering machinery. The detergent compositions and methods of employing the same beneficially clean and prevent redeposition of soils containing high concentrations of oil and metal particulates, as are customary in industrial laundering soils.

主权项

1. A method for removing soils from a soft surface and preventing redeposition comprising:
applying a detergent composition to a soft surface in need of cleaning within a washing machine, wherein the detergent composition comprises an acrylic acid polymer comprising from about 0.1-15 wt-% of the detergent composition, surfactants comprising greater than 50 wt-% of the detergent composition, solvent comprising from about 1-50 wt-% of the detergent composition, and a water conditioning polymer comprising from about 0.1-15 wt-% of the detergent composition, wherein the acrylic acid polymer has at least 40 wt-% polymerized residues of acrylic monomers; washing the soft surface, wherein the washing with said detergent composition suspends high oil and metal content soils presents in industrial soils and prevents redeposition in industrial laundering applications; and rinsing and/or wiping the detergent composition from the soft surface.
