FIELD: chemistry.

SUBSTANCE: present invention relates to a surfactant composition which contains a surfactant with high concentration, having fluidity in a wide range of concentrations. Described is a surfactant composition suitable as a detergent, containing component A, component B, component C and component D described below, where total content of component A, component B and component C is 45 wt % or more and 80 wt % or less; weight ratio (A+B)/C of total content of component A and component B to content of component C ranges from 20/80 to 80/20; and weight ratio A/B of content of component A to content of component B ranges from 98/2 to 45/55, where components are as follows: A: internal olefin sulphonate having 12 or more and 24 or less carbon atoms; B: an anionic surfactant other than component A; C: nonionic surfactant and D: water, wherein: an anionic surfactant is at least one compound selected from a group comprising a salt of a sulfuric ester having from 10 to 22 carbon atoms, sulphonate having 10 to 22 carbon atoms, a fatty acid salt having 10 to 22 carbon atoms, carboxylate having 10 to 22 carbon atoms, phosphoric acid ester salt having 10 to 22 carbon atoms, and an amino acid salt having an acyl group with 10–22 carbon atoms, and the nonionic surfactant is at least one compound selected from a group comprising a polyalkylene glycol type nonionic surfactant, a polyatomic alcohol-type nonionic surfactant and fatty acid alkanolamide.

EFFECT: technical result is creation of surface-active composition containing high concentration of surfactant and fluidity in a wide range of concentrations.
