Abstract

A surfactant composition containing: (a) from 2 to 20% by weight of a betaine having a fatty residue containing exactly 12 carbon atoms; (b) from 3 to 18% by weight of an alkyl and/or alkenyl oligoglycoside; and (c) from 15 to 35% by weight of a fatty alcohol ether sulfate, all weights being based on the weight of the composition.

Claims

1. A surfactant composition comprising:

(a) from 5 to 15% by weight of a single betaine, wherein the betaine has a fatty residue containing exactly 12 carbon atoms;

(b) from 3 to 18% by weight of an alkyl and/or alkenyl oligoglycoside; and

(c) from 20 to 35% by weight of a fatty alcohol ether sulfate, all weights being based on the weight of the composition.

2. The composition of claim 1 wherein the alkyl and/or alkenyl oligoglycoside is present in the composition in an amount of from 5 to 15% by weight, based on the weight of the composition.

3. The composition of claim 1 wherein the fatty alcohol ether sulfate is present in the composition in an amount of from 20 to 25% by weight, based on the weight of the composition.

4. The composition of claim 1 further comprising up to 5% by weight, based on the weight of the composition, of a fatty alcohol ethoxylate.

5. The composition of claim 4 wherein the fatty alcohol ethoxylate is present in the composition in an amount of from 1 to 3% by weight, based on the weight of the composition.

6. The composition of claim 1 further comprising up to 5% by weight, based on the weight of the composition, of an amine oxide.

7. The composition of claim 6 wherein the amine oxide is present in the composition in an amount of from 1 to 3% by weight, based on the weight of the composition.

8. A hard surface cleaning composition containing from 30 to 100% by weight of the surfactant composition of claim 1.

9. The composition of claim 8 wherein the surfactant composition is present in an amount of from 50 to 70% by weight, based on the weight of the hard surface cleaning composition.

10. A process for cleaning a hard surface comprising contacting the surface with a composition containing:

(a) from 5 to 15% by weight of a single betaine wherein the betaine has a fatty residue containing exactly 12 carbon atoms;

(b) from 3 to 18% by weight of an alkyl and/or alkenyl oligoglycoside; and

(c) from 20 to 35% by weight of a fatty alcohol ether sulfate, all weights being based on the weight of the composition.

11. The process of claim 10 wherein the alkyl and/or alkenyl oligoglycoside is present in the composition in an amount of from 5 to 15% by weight, based on the weight of the composition.

12. The process of claim 10 wherein the fatty alcohol ether sulfate is present in the composition in an amount of from 20 to 25% by weight, based on the weight of the composition.

13. The process of claim 10 wherein the composition further comprises up to 5% by weight, based on the weight of the composition, of a fatty alcohol ethoxylate.

14. The process of claim 13 wherein the fatty alcohol ethoxylate is present in the composition in an amount of from 1 to 3% by weight, based on the weight of the composition.

15. The process of claim 10 wherein the composition further comprises up to 5% by weight, based on the weight of the composition, of an amine oxide.

16. The process of claim 15 herein the amine oxide is present in the composition in an amount of from 1 to 3% by weight, based on the weight of the composition.
