Surfactant composition

Abstract

Provided is a surfactant composition having excellent fluidity after long-term storage at a low temperature (5° C.) and excellent foamability when diluted. The surfactant composition containing the following components (A), (B) and (C), wherein the content of the component (A) is 40 to 75 wt. %, (A) a sulfate surfactant represented by the following general formula (1): R1O—(PO)m(EO)nSO3M   (1), wherein R1 represents a hydrocarbon group having 8 to 18 carbon atoms; PO represents a propyleneoxy group; EO represents an ethyleneoxy group; m and n represent an average mole number of added PO and EO, respectively, are the same as or different from each other, and independently represent a number within the ranges of 0<m<1 and 0<n<5; and M represents a cation; (B) one or more of compound(s) selected from the group consisting of the following (B-1) and (B-2): (B-1) an alkylene oxide adduct of alcohol represented by the following general formula (2): R2O-(AO)t—R3   (2), wherein R2 represents an alkyl or alkenyl group having 8 to 10 carbon atoms; AO represents an alkyleneoxy group having 2 to 4 carbon atoms; t represents an average mole number of added AO and represents a number of 0.5 to 4.0; and R3 represents a hydrogen atom or a methyl group; and (B-2) a monoalkyl or monoalkenyl glyceryl ether; and (C) a water-soluble salt.
