  • Publication number: 20120157369
    Abstract: The present invention comprises polymers having optionally substituted aromatic residues in the polymer backbone and/or side chains, useful for the removal and/or dispersion of hydrophilic soils from textiles. The present invention also comprises a method for the removal of hydrophilic soils from textiles comprising the step of contacting the soil with a polymer that comprises optionally substituted aromatic residues in the backbone and/or side chains. The present inventive polymers and method are particularly useful in the context of washing or pretreatment agents that effectively remove red wine, fruit, vegetable, food product, or beverage stains from textiles.
