A softener composition, which contains tri-long-chain alkyl quaternary ammonium salt that has been considered to be difficult to use as a softener base agent, and which can provide a softener composition that provides a sufficient softening performance, is provided with (A) a cationic surfactant comprising at least one selected from the group consisting of quaternary ammonium salts represented by the formulae (I), (II) or (III), wherein the ratio of quaternary ammonium salt represented by the formula (I) to the total amount of these salts exceeds 50 weight %, with the ratio thereof represented by (III) being set to not more than 10 %, and (B) at least one nonionic surfactant. In this case, (A) may include tertiary amine. <CHEM> <CHEM> <CHEM> (wherein, R<1>, R<2> and R<3> represent long-chain alkyl groups, etc. having total carbon atoms of 8 to 40, which may be intersected by an ether group, an ester group or an amide group; R<4> represents an alkyl group, etc. having carbon atoms of 1 to 6, and X<-> represents an anionic group.) |
