Claims
- 1. A process of bleaching a fabric with a liquid composition having a pH from 1 to 5 comprising from 0.01% to 15% by weight of the total composition of peroxygen bleach, and a soil dispersing agent which is an ethoxylated amine polymer of the formula: whereas X is a Hydrogen; w is 1 or 0; x+y+z is at least 2, y+z is at least 2; and n is at least 3; said polymer selected from the group consisting of ethoxylated polyethyleneamines having a molecular weight of from 140 to 310 prior to ethoxylation and ethoxylated polyethyleneimines having a molecular weight of 600 to 1800 prior to ethoxylation, said process comprising the step of applying said composition in its neat form onto at least a portion of the fabric, before said fabric is washed.
- 2. A process according to claim 1 wherein said composition is allowed to remain in contact with said fabric from 1 minute to 1 hour, before said fabric is washed.
- 3. A process according to claim 2 wherein said composition is allowed to remain in contact with said fabric from 1 minute to 30 minutes, before said fabric is washed.
- 4. A process according to claim 2 wherein said composition is allowed to remain in contact with said fabric from 2 minutes to 10 minutes, before said fabric is washed.
- 5. A process according to claim 1, wherein said peroxygen bleach is hydrogen peroxide or a water-soluble source thereof selected from the group consisting of percarbonate, persilicate, persulphate, perborate, peroxyacids, hydroperoxides, diacyl peroxides and mixtures thereof.
- 6. A process according to claim 1 wherein said composition comprises from 0.1% to about 12% by weight of the total composition of said peroxygen bleach, or mixtures thereof.
- 7. A process according to claim 1 wherein said composition comprises from 0.5% to 10% by weight of the total composition of said peroxygen bleach, or mixtures thereof.
- 8. A process according to claim 1 wherein said composition comprises from 0.01% to 20% by weight of the total composition of said soil dispersing agent, or mixtures thereof.
- 9. A process according to claim 8 wherein said composition comprises from 0.1% to 10% by weight of the total composition of said soil dispersing agent, or mixtures thereof.
- 10. A process according to claim 8 wherein said composition comprises from 0.2% to about 4% by weight of the total composition of said soil dispersing agent, or mixtures thereof.
- 11. A process according to claim 1 wherein said composition further comprises a bleach activator or mixtures thereof.
- 12. A process according to claim 2 wherein said composition comprises said bleach activator or mixtures thereof, at a level of from 0.01% to 20% by weight of the total composition.
- 13. A process according to claim 12 wherein said composition comprises said bleach activator or mixtures thereof at a level of from 1% to 10% by weight of the total composition.
- 14. A process according to claim 12 wherein said bleach activator is selected from the group consisting of acetyl triethyl citrate, tetracetyl ethylene diamine, sodium 3,5,5 trimethyl hexanoyloxybenzene sulphonate, diperoxy dodecanoic acid, nonylamide of peroxyadipic acid, n-nonanoyloxybenzenesulphonate, N-acyl caprolactam, substituted and unsubstituted benzoyl caprolactam, octanoyl caprolactam, nonanoyl caprolactam, hexanoyl caprolactam, decanoyl caprolactam, undecenoyl caprolactam, formyl caprolactam, acetyl caprolactam, propanoyl caprolactam, butanoyl caprolactam, pentanoyl caprolactam and mixtures thereof.
