Abstract

The present invention is a surfactant composition containing (a) a branched alkyl sulfosuccinate ester having a branched alkyl group with 9 or 10 carbons and (b) a surfactant [excluding (a)].

First claim

The invention claimed is:

1. A surfactant composition, comprising:
component (a): an alkali metal salt of a branched alkyl sulfosuccinate ester having a branched alkyl group, wherein the branched alkyl group has a main chain with 6 or 7 carbons and one or more side chains and the side chains have 3 carbons in total; and
component (b): a surfactant other than the component (a),
wherein a mass ratio of the component (a) to the component (b) is 0.05 or more and 5 or less.

2. The surfactant composition according to claim 1 , wherein the branched alkyl group of the component (a) is a branched alkyl group selected from the group consisting of a 2-propylheptyl group and a 3,5,5-trimethylhexyl group.

3. The surfactant composition according to claim 1 , wherein the component (b) is one or more surfactants selected from the group consisting of a nonionic surfactant and an anionic surfactant.

4. A method for controlling foaming performance of a composition comprising a component (b), the method comprising:
adding component (a), which is an alkali metal salt of a branched alkyl sulfosuccinate ester having branched alkyl group, wherein the branched alkyl group has a main chain with 6 or 7 carbons and one or more side chains and the side chains have 3 carbons in total, to the composition comprising the component (b), which is a surfactant other than the component (a),
wherein a mass ratio of the component (a) to the component (b) is 0.05 or more and 5 or less.

5. The method according to claim 4 , wherein the component (b) is one or more surfactants selected from the group consisting of a nonionic surfactant and an anionic surfactant.

6. The method according to claim 4 , wherein the addition of the component (a) improves foamability and/or stabilizes foam.

7. The surfactant composition according to claim 1 , further comprising:
component (c): one or more water-soluble organic solvents selected from the group consisting of benzyl alcohol, ethanol, propylene glycol, butyldiglycol, and phenoxyethanol.

8. The surfactant composition according to claim 1 , wherein the component (a) is a foaming control agent.

9. The method according to claim 4 , wherein the composition further comprises:
component c), which is one or more water-soluble organic solvents selected from the group consisting of benzyl alcohol, ethanol, propylene glycol, butyldiglycol, and phenoxyethanol.

10. The method according to claim 4 , further comprising:
discharging the composition in foam form from a container having a foam discharge mechanism.
