Abstract

Dual-usage aqueous liquid detergent compositions having suds compatibility and improved cleaning, said composition containing from about 1% to about 60%, by weight of the composition, of a surfactant system wherein said surfactant system contains at least 35%, by weight of the surfactant system, of alkylethoxysulfate; from 0% to about 10%, by weight of the surfactant system, of nonionic surfactant; from 0% to about 10%, by weight of the surfactant system, of soap; further contains from about 0.001% to about 4.0%, by weight of the composition, of an anti-foam selected from organomodified silicone polymers with aryl or alkylaryl substituents combined with silicone resin and the primary filler is modified silica; and mixtures thereof; and contains from about 0.01% to about 2.5%, by weight of the composition, of a structurant.

b) from about 0.001% to about 4.0%, by weight of the composition, of an anti-foam selected from organomodified silicone polymers with aryl or alkylaryl substituents combined with silicone resin and a primary filler, which is modified silica;
c) from about 0.01% to about 2.5%, by weight of the composition, of a structurant, wherein the structurant is selected from: crystalline, hydroxyl-containing stabilizers, polymer gums, and mixtures thereof.

2. An aqueous liquid detergent composition having suds compatibility and improved cleaning, said composition comprising:
a) from about 1% to about 60%, by weight of the composition, of a surfactant system wherein said surfactant system comprises:
i) at least 35%, by weight of the surfactant system, of alkylethoxysulfate;
ii) linear alkylbenzene sulfonate
iii) soap

b) from about 0.001% to about 4.0%, by weight of the composition, of an anti-foam selected from organomodified silicone polymers with aryl or alkylaryl substituents combined with silicone resin and a primary filler, which is modified silica;
c) from about 0.01% to about 2.5%, by weight of the composition, of a structurant, wherein the structurant is selected from: crystalline, hydroxyl-containing stabilizers, polymer gums, and mixtures thereof;
d) amine ethoxylate polymer.

3. A dual-usage aqueous liquid detergent composition having suds compatibility and improved cleaning, said composition comprising:
a) from about 1% to about 60%, by weight of the composition, of a surfactant system wherein said surfactant system comprises:
i) at least 35%, by weight of the surfactant system, of alkylethoxysulfate;
ii) linear alkylbenzene sulfonate
iii) soap

b) from about 0.001% to about 4.0%, by weight of the composition, of an anti-foam selected from organomodified silicone polymers with aryl or alkylaryl substituents combined with silicone resin and a primary filler, which is modified silica;
c) from about 0.01% to about 2.5%, by weight of the composition, of a structurant, wherein the structurant is selected from: crystalline, hydroxyl-containing stabilizers, polymer gums, and mixtures thereof;
d) amine ethoxylate polymer;
wherein said detergent composition is adapted to be used in both a top-loading washing machine and a front-loading washing machine.

4. An aqueous liquid detergent composition according to claim 1 , wherein the surfactant system further comprises an additional surfactant selected from the group consisting of anionic surfactants, cationic surfactants, zwitterionic surfactants, and mixtures thereof.

5. An aqueous liquid detergent composition according to claim 1 wherein the anti-foam is selected from:
a) mixtures of from about 80 to about 92% ethylmethyl, methyl(2-phenylpropyl) siloxane; from about 5 to about 14% MQ resin in octyl stearate; and from about 3 to about 7% modified silica;
b) mixtures of from about 78 to about 92% ethylmethyl, methyl(2-phenylpropyl) siloxane; from about 3 to about 10% MQ resin in octyl stearate; from about 4 to about 12% modified silica; and
c) mixtures thereof;
wherein percentages are by weight of the anti-foam.

6. An aqueous liquid detergent composition according to claim 1 wherein the composition comprises from about 5% to about 50%, by weight of the composition, of the surfactant system.

7. An aqueous liquid detergent composition according to claim 1 , wherein the composition comprises from about 15% to about 35%, by weight of the composition, of the surfactant system.

8. An aqueous liquid detergent composition according to claim 1 wherein the composition comprises from about 0.01% to about 2.0, by weight of the composition, of the silicone anti-foam.

9. An aqueous liquid detergent composition according to claim 1 wherein the surfactant system comprises from at least 50%, by weight of the surfactant system, of alkylethoxysulfate.

10.
