Abstract
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.
