Abstract
Fabric treatment compositions that include certain polymer systems, such as systems that include a first polymer that is a soil release polymer and a second polymer that is a graft copolymer (e.g., a PEG/vinyl acetate polymer), an alkoxylated polyalkyleneimine polymer, or a mixture thereof. Related processes and uses.
Claims19
A fabric treatment composition comprising:
- (a) from about 1% to about 25%, by weight of the composition, of a first polymer, the first polymer being a terephthalate-derived soil release polymer (SRP);
- and
- (b) from about 1% to about 25%, by weight of the composition, of a second polymer, the second polymer being a graft copolymer,
- wherein the graft copolymer comprises
- i) water-soluble polyalkylene oxides as a graft base, and
- ii) one or more side chains formed by polymerization of a vinyl ester component,
- wherein the graft copolymer comprises from 25 to 60% by weight of the graft base (i) and from 40 to 75% by weight of the vinyl ester component (ii);
- wherein the composition comprises less than about 5%, by weight of the composition, of anionic surfactant;
- wherein the composition is in the form of a liquid.
