ABSTRACT:
A stable fabric softening, soil release promoting, enzyme-containing nonionic liquid detergent, preferably transparent or translucent, comprises a detersive proportion of a synthetic organic nonionic detergent, a soil release promoting proportion of a particular type of soil release promoting copolymer of polyethylene terephthalate and polyoxyethylene terephthalate, a softening proportion of a quaternary ammonium halide fabric softener, a proportion of enzyme sufficient to enzymatically hydrolyze proteinaceous and/or amylaceous soils on fabrics during washing thereof with an aqueous washing solution of the liquid detergent, a stabilizing proportion of a stabilizer for the enzyme(s), and an aqueous medium. The pH is in a certain range and the proportion of ionizable material present is limited. The described liquid detergent can be clear in appearance and is non-separating and of improved stability on storage (especially important with respect to enzymatic stability and effectiveness), with substantial retention of soil release promoting and hydrolyzing characteristics, so that laundry containing polyester materials is effectively cleaned and readily releases soil from it upon washing with the liquid detergent.
