Abstract:
A softener composition which comprises a compound having one or more C8-36 hydrocarbon groups and two or more groups selected from an amino group and a quaternary ammonium group in the molecule (component (a)), an anionic surfactant having a C8-36 hydrocarbon group (component (b)) and a nonionic surfactant (component (c)), wherein the molar ratio of the component (a) to the component (b) is from 90/10 to 50/50,wherein the component (a) is a compound having at least one C8-36 hydrocarbon group, at least one quaternary ammonium group and at least one tertiary amino group, and the cation equivalent of the quaternary ammonium group of the component (a) to the anion equivalent of the component (b) is from 90/10 to 40/60, wherein the component (a) is a compound represented by the formula (2): R1â€”[Aâ€”P]nâ€”[Bâ€”Q]mâ€”Câ€”R2.aXâˆ’â€ƒâ€ƒ(2) wherein at least one of R1 and R2 is a C8-36 alkyl or alkenyl group interrupted by an ester group, and the other group is a C1-5 alkyl or hydroxyalkyl group when only one of R1 and R2 is a C8-36 alkyl or alkenyl group interrupted by an ester group; A, B and C each represent a group â€”N+(R3) (R4)â€” or â€”N(R5)â€” provided that at least one of A, B and C is â€”N+(R3) (R4)â€” and A, B and C are simultaneously not all â€”N+(R3) (R4)â€”, R3, R4 and R5 are the same as or different from one another and represent a C1-5 alkyl or hydroxyalkyl group; P and Q each represent a C1-5 alkylene group and are unsubstituted and uninterrupted; â€œaâ€  is the number of â€”N+(R3) (R4)â€” groups in A, B and C; â€œnâ€  is a number of 1 to 3, and â€œinâ€  is a number of 0 to 2; and Xâˆ’ is an anion.
