A soil release promoting detergent composition of improved soil release promoting properties in cold water washing of polyester-containing fabrics that have been soiled with oily soils, which improved soil release is due to the presence therein of narrow range ethoxylate (NRE) nonionic detergent and soil release promoting polyethylene terephthalate- polyoxyethylene terephthalate (PET-POET) copolymer instead of broad range ethoxylate (BRE) nonionic detergent and PET-POET copolymer, comprises a detersive proportion of such a NRE type of a nonionic detergent, which is a polyethoxylated lipophile, ethoxylated with an average of 5 to 10 ethylene oxide groups per mole, and with at least 70% of the ethylene oxide being in polyethoxy groups of 4 to 12 ethylene oxides, and a soil release promoting proportion of PET- POET copolymer soil release promoting agent. |
