Claims
- 1. A detergent composition comprising an anionic surfactant, present at a level of from 0.5% to 60% by weight, a cationic surfactant, present at a level of from 0.01% to 30%by weight, and from about 1.0% to about 7% by weight of an acid source and from about 10% to about 30% by weight of an alkali source wherein said acid source and alkali source are capable of reacting together in the presence of water and wherein the pH of a 1% solution of said detergent composition in distilled water is from about 10 to about 12.5.
- 2. A detergent composition according to claim 1 wherein said cationic surfactant is selected from the group consisting of cationic ester surfactants, cationic mono-alkoxylated amine surfactants, cationic bis-alkoxylated amine surfactants and mixtures thereof.
- 3. A detergent composition according to claim 1 wherein said anionic surfactant is present at a level of from 3% to 50% by weight of the composition.
- 4. A detergent composition according to claim 1 wherein said anionic surfactant is present at a level of from 6% to 20% by weight of the composition.
- 5. A detergent composition according to claim 1 wherein said cationic surfactant is present at a level of from 0.1% to 20% by weight of the composition.
- 6. A detergent composition according to claim 1 wherein the cationic surfactant is present at a level of from 0.5% to 3% by weight of the composition.
- 7. A detergent composition according to claim 2 wherein said cationic ester surfactant is selected from the choline esters having the formula: wherein m is from 1 to 4 and R1 is a C11-C19 linear or branched alkyl chain.
- 8. A detergent composition according to claim 2 wherein said cationic ester surfactant contains a positively charged amine group, substituted with one or two methyl groups and one or two hydroxyethyl or hydroxypropyl groups.
- 9. A detergent composition according to claim 2 wherein said cationic mono-alkoxylated amine contains a positively charged amine group, which is substituted with one or two methyl groups, one or two C6-C18 alkyl groups and one (poly)ethoxy group, with an ethoxylation number of from 1 to 4.
- 10. A detergent composition according to claim 9 wherein said positively charged amine group is substituted with one or two C6-C11 alkyl groups.
- 11. A detergent composition according to claim 2 wherein said cationic bis-ethoxylated amine surfactant contains a positively charged amine group, which is substituted with one methyl group, one C6-C18 alkyl group and two ethoxy groups, with each independently an ethoxylation number of from 1 to 4.
- 12. A detergent composition according to claim 11 wherein said positively charged amine group is substituted with one C6-C11 alkyl group.
- 13. A detergent composition or component thereof according to claim 1 wherein the ratio of anionic surfactant to cationic surfactant is from 25:1 to 1:3.
- 14. A detergent composition according to claim 1 wherein the alkali source comprises an alkaline salt selected from an alkali metal or alkaline earth metal carbonate, bicarbonate, sesqui-carbonate, or alkali metal percarbonate salt.
- 15. A detergent composition according to claim 1 wherein the acid source comprises an organic, mineral or inorganic acid.
- 16. A detergent composition according to claim 15 wherein the acid source is glutaric acid, succinic acid, tartaric acid, adipic acid, monosodium phosphate, sodium hydrogen sulfate or boric acid.
- 17. A detergent composition according to claim 15 wherein the acid source is citric acid.
- 18. A detergent composition according to claim 1 wherein 100% of the acid source has a particle size of no greater than 710 microns.
- 19. A method of washing laundry in a domestic washing machine comprising, introducing into a dispensing device which is placed in the drum of the washing machine, or introducing into the dispensing drawer of a washing machine, an effective amount of a detergent composition according to claim 1.
