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.
