A softener composition, which contains tri-long-chainnalkyl quaternary ammonium salt that has been considered to bendifficult to use as a softener base agent, and which can providena softener composition that provides a sufficient softeningnperformance, is provided with (A) a cationic surfactantncomprising at least one selected from the group consisting ofnquaternary ammonium salts represented by the formulae (I), (II)nor (III), wherein the ratio of quaternary ammonium saltnrepresented by the formula (I) to the total amount of these saltsnexceeds 50 weight %, with the ratio thereof represented by (III)nbeing set to not more than 10 %, and (B) at least one nonionicnsurfactant. In this case, (A) may include tertiary amine.n n n n(wherein, R 1 , R 2 and R 3 represent long-chain alkyl groups, etc.nhaving total carbon atoms of 8 to 40, which may be intersectednby an ether group, an ester group or an amide group; R 4 representsnan alkyl group, etc. having carbon atoms of 1 to 6, and X - nrepresents an anionic group.) |
