Abstract

Official abstract text for this publication.

Provided is a surfactant composition which includes high concentrations of a surfactant, has fluidity in a wide concentration range, and does not become clouded when diluted with hard water. This surfactant composition includes component A, component B, and component C described below, wherein a total content of the component A and the component B is 35 to 80% by mass and wherein the component A is at least one sulfonate compound selected from the group consisting of a hydroxyalkane sulfonate and an olefin sulfonate, the component B is a polyoxyalkylene alkyl ether, and the component C is water.

First claim

Opening claim text (preview).

The invention claimed is: 1. A surfactant composition including component A, component B, and component C described below, wherein a total content of the component A and the component B is 45% by mass or more and 80% by mass or less and wherein the component A is a hydroxyalkane sulfonate having 12 to 24 carbon atoms and an internal olefin sulfonate having 12 to 24 carbon atoms, the component B is a polyoxyalkylene alkyl ether of the formula R—O-(AO) n —H wherein R is a hydrocarbon group having 8 to 22 carbon atoms, AO is ethylene oxy, propylene oxy, or butylene oxy, and n is 5 or more and 100 or less, and the component C is water, wherein a viscosity of the composition measured by a tuning fork type vibrational viscometer at 25° C. is 8000 mPa·s or less. 2. The surfactant composition according to claim 1 , wherein a mass ratio AB of the content of the component A to the content of the component B is from 20/80 to 80/20. 3. The surfactant composition according to claim 1 , wherein the sulfonate compound contains 40% by mass or less of a sulfonate compound having a sulfonic acid group at 2-position. 4. The surfactant composition according to claim 1 , wherein the mass ratio of the content of the hydroxyalkane sulfonate to the content of the olefin sulfonate is from 50/50 to 99/1. 5. The surfactant composition according to claim 1 , which is a detergent. 6. A cleaning method using the surfactant composition according to claim 1 . 7. The surfactant composition according to claim 2 , wherein the sulfonate compound contains 40% by mass or less of a sulfonate compound having a sulfonic acid group at 2-position. 8. The surfactant composition according to claim 2 , wherein the mass ratio of the content of the hydroxyalkane sulfonate to the content of the olefin sulfonate is from 50/50 to 99/1. 9. The surfactant composition according to claim 3 , wherein the mass ratio of the content of the hydroxyalkane sulfonate to the content of the olefin sulfonate is from 50/50 to 99/1.
