Abstract
A composition for applying a non-permanent soil-release finish to fabrics from dilute solution comprising a polycarboxylate polymer having an acid equivalent weight of from about 110 to 175, and a water-soluble salt of a polyvalent metal. A preferred polymer is derived from an ethylenically unsaturated monocarboxylic acid and an alkyl acrylate. The composition is particularly useful for applying a soil-release finish in the rinse cycle of a home laundry process.
