- (e) from about 45 to 60%, by weight, water, said liquid detergent composition being free of an amine oxide surfactant and providing effective detergency at a product concentration equivalent to about 1/4 cup under U.S. washing conditions.
- 11. A method according to claim 10 wherein said builder salt is sodium citrate.
- 12. A method according to claim 10 wherein said nonionic detergent compound is the condensation product of 6 to 7 moles of ethylene oxide with one mole of an aliphatic alcohol containing 12 to 13 carbon atoms.
- 13. A method according to claim 10 wherein said liquid detergent composition is substantially free of a C.sub.10 -C.sub.18 alkyl benzene sulfonate anionic detergent.
- 14. A method according to claim 10 wherein said liquid detergent composition is substantially free of an alkylene glycol.
- 15. A method according to claim 10 wherein the concentration of builder salt is about 17% and the range of nonionic detergent compound is from about 16 to 18%, by weight, of the composition.
- 16. A method according to claim 10 wherein the concentration of said solubilizer in the liquid composition is about 7%, by weight.
- 17. A method of laundering comprising
- (i) adding an effective amount of a concentrated aqueous single-phase homogeneous liquid detergent composition to an aqueous liquid to form a wash solution, said homogeneous liquid detergent comprising:
- (a) from about 15 to 18%, by weight, of a water-soluble non-phosphate detergent builder salt;
- (b) from about 15 to 23%, by weight, of a surface active nonionic detergent compound which is the condensation product of 5 to 9 moles of ethylene oxide with one mole of an aliphatic alcohol containing 12 to 15 carbon atoms;
- (c) from about 1 to 6%, by weight, of at least one amphoteric detergent composed selected from the group consisting of cocobetaine and cocoamido betaine;
- (d) from about 5 to 8%, by weight, of a solubilizer selected from the group consisting of alkali metal salts of (i) nonyl succinic anhydride and (ii) nonyl maleic anhydride; and
- (e) from about 45 to 60%, by weight, water, said liquid detergent composition being free of an amine oxide surfactant and providing effective detergency at a product concentration equivalent to about 1/4 cup under U.S. washing conditions.
- 18. A method according to claim 17 wherein said builder salt is sodium citrate.
- 19. A method according to claim 17 wherein said liquid detergent composition is substantially free of a C.sub.10 -C.sub.18 alkyl benzene sulfonate anionic detergent.
- 20. A method according to claim 17 wherein said liquid detergent composition is substantially free of an alkylene glycol.
- 21. A method according to claim 17 wherein the concentration of detergent composition in the wash water is about 0.1% by weight.
