PCT No. PCT/JP93/00811 Sec. 371 Date Nov. 22, 1994 Sec. 102(e) Date Nov. 22, 1994 PCT Filed Jun. 16, 1993 PCT Pub. No. WO93/25646 PCT Pub. Date Dec. 23, 1993There is disclosed a detergent composition containing, as an essential ingredient, at least one member selected from three types of alpha -sulfo-fatty acid derivatives as represented by following formulas (1), (2) and (3): (1) (2) (3) where R1, R2, R3 and R4 are each an alkyl group or an alkenyl group, each having from 6 to 24 carbon atoms; R5 is an alkyl group having from 1 to 4 carbon atoms; M1, M2, M3 and M4 are each a hydrogen atom or a cation capable of forming a salt; AO is an oxyalkylene group or a polyvalent alcohol residue; and p, m and n are each a positive number. The detergent compositions are very low in irritability to the body and have a low critical micelle concentration and a low Krafft point. Further, they are highly soluble in water and they can be used in the form of powder or liquid.
