A stable soil release promoting enzymatic primarily nonionic liquid detergent composition comprises a synthetic organic nonionic detergent, an anionic sulf(on)ated synthetic organic detergent, a particular type of soil release promoting copolymer of polyethylene terephthalate (PET) and polyoxyethylene terephthalate (POET), a proportion of enzyme(s) sufficient to enzymatically hydrolyze proteinaceous and/or amylaceous soils on fabrics during washing thereof with an aqueous washing solution of the liquid detergent, a fluorescent brightener, a stabilizing proportion of a stabilizer for the enzyme(s), which also acts as a buffer for the liquid detergent composition to maintain the pH in a certain neutral or slightly acidic range to stabilize the PET - POET copolymer and the fluorescent brightener, and an aqueous medium. The described composition is non-separating and is chemically stable on storage. It substantially retains its soil hydrolyzing, fluorescent brightening and soil release promoting characteristics on storage, so that laundry washed with it is effectively cleaned, brightened, and treated. Also within the invention are processes for manufacturing the product and for utilizing it to wash laundry. |
