Abstract
A soil release promoting, enzyme-containing nonionic detergent based liquid detergent, of high active ingredients concentrations and preferably transparent or translucent, comprises a synthetic organic nonionic detergent, a higher fatty alcohol polyethoxylate sulfate, a particular type of soil release promoting copolymer of polyethylene terephthalate and polyoxyethylene terephthalate, 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 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, with substantial retention of soil release promoting and soil hydrolyzing characteristics, so that laundry containing polyester materials is effectively cleaned and soils are readily released from it when it is washed with the liquid detergent.
