Abstract
A composition comprising a conventional surfactant, a gemini surfactant and a polymeric soil release agent. The conventional surfactant comprises a hydrophilic group and a hydrophobic group. The gemini surfactant comprises two surfactant moieties attached to each other by a spacer moiety; each surfactant moiety having at least one hydrophilic group and at least one hydrophobic group. The polymeric soil release agent can be any conventional polymeric soil release agent, but preferably comprising PET-POET copolymer. The compositions are useful as surfactant additive packages, detergents and fabric softeners.
