Claims
- 1. A process of treating a fabric which comprises the step of contacting said fabric with a bleaching composition, in its neat form, wherein said bleaching composition comprises a peroxygen bleach and a high molecular weight polymer selected from the group consisting of a homopolymer of acrylic acid having a molecular weight of from 1×105 to 1×108, copolymers of acrylic acid having a molecular weights of from 1×105 to 1×108 and mixtures thereof.
- 2. A process according to claim 1 wherein said fabrics are coloured.
- 3. A process according to claim 1 wherein said fabrics are delicate fabrics.
- 4. A process according to claim 1 wherein said high molecular weight polymer is crosslinked or partially crosslinked.
- 5. A process according to claim 1 wherein said bleaching compositions comprises from 0.001% to 10% by weight of the total composition of said high molecular weight polymer.
- 6. A process or the use according to claim 1 wherein said high molecular weight polymer has a molecular weight of from 1×105 to 1×107.
- 7. A process according to claim 1 wherein said peroxygen bleach is hydrogen peroxide or a water soluble source thereof.
- 8. A process according to claim 1 wherein said solvent is water.
- 9. A process according to claim 1 wherein said bleaching composition comprises from 0.01% to 20% by weight of the total composition of said peroxygen bleach.
- 10. A process according to claim 1 wherein said bleaching composition further comprises a surfactant.
- 11. A process according to claim 10 wherein said surfactant is a nonionic surfactant or a zwitterionic betaine surfactant or a mixture thereof.
- 12. A method of reducing the evaporation of a solvent contained in a peroxygen bleach-containing composition, said method comprising combining a high molecular weight polymer selected from the group consisting of a homopolymer of acrylic acid having a molecular weight of from 1×105 to 1×108, copolymers of acrylic acid having a molecular weights of from 1×105 to 1×108 and mixtures thereof with said peroxygen bleach-containing composition.
