摘要
Narrow range ethoxylate nonionic detergents, in combination with soil release promoting polyethylene terephthalate-polyoxyethylene terephthalate (PET-POET) copolymer (in place of broad range ethoxylate nonionic detergent and PET-POET copolymer) are of significantly and unexpectedly improved soil release promoting activity in built synthetic organic detergent compositions, of either the phosphate-built or non- phosphate-built types. Preferably, there will be present with the PET- POET copolymer a stabilizing proportion of polyacrylate, to stabilize the PET-POET copolymer against deterioration and loss of soil release promoting activity on storage at elevated temperature, especially when in contact with alkaline components of the detergent composition. The improved soil release promoting activity is most pronounced when the laundry to be washed and treated is subjected to repeated launderings with the invented compositions in cold water and when it includes polyester-containing fibrous materials.
