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.
Claims20
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 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, an alkoxylated polyalkyleneimine polymer, or a mixture thereof,
- wherein the the graft copolymer, if present, 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 composition comprises less than about 5%, by weight of the composition, of anionic surfactant.

A fabric treatment composition comprising:
- (a) a first polymer, the first polymer being a soil release polymer;
- and
- (b) a second polymer, the second polymer being a graft copolymer, an alkoxylated polyalkyleneimine, or mixtures thereof,
- wherein the graft copolymer, if present, 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 total weight of (a)+(b) is from about 2% to about 30% by weight of the composition.
4 more elements
A process of treating a fabric, the process comprising the steps of:
- contacting a fabric with an aqueous treatment liquor, the aqueous treatment liquor comprising
- from about 10 to about 100 ppm of a first polymer that is a soil release polymer, preferably a terephthalate-derived soil release polymer, and
- from about 10 to about 100 ppm of a second polymer selected from a graft copolymer (preferably a PEG/vinyl acetate graft copolymer), an alkoxylated polyalkyleneimine polymer, or mixtures thereof.
