Patent ID: 6838427

Claim:
A softener composition comprising the following component (a), component (b) and component (c), wherein the mole ratio between the component (a), the component (b) and the component (c) satisfies the following relationship: [(a)+(b)]/(c)=9/1 to 4/6: (a) a tertiary amine represented by formula (1) or a salt thereof: wherein R 1 represents an alkyl group or an alkenyl group having 13 to 36 carbon atoms, R 2 represents an alkylene group having 1 to 6 carbon atoms, R 3 and R 4 respectively represent an alkyl group or a hydroxyalkyl group having 1 to 3 carbon atoms, A represents a group selected from —COO—, —OCO—, —CONH— or —NHCO—, a denotes a number of 0 or 1; (b) a quaternary ammonium salt represented by the formula (4): wherein R 15 and R 17 respectively represent an alkyl group or an alkenyl group having 8 to 36 carbon atoms, R 16 and R 18 respectively represent an alkylene group having 1 to 6 carbon atoms, R 19 represents an alkyl or hydroxyalkyl group having 1 to 3 carbon atoms or a group represented by the formula R 15 —[F—R 16 ] e —, R 20 represents an alkyl group or a hydroxyalkyl group having 1 to 3 carbon atoms, F and G respectively represent a group selected from —COO—, —OCO—, —CONH— and —NHCO—, e and f respectively denote a number of 0 or 1 and Z − represents an anionic group; (c) an anionic surfactant having a hydrocarbon group having 8 to 36 carbon atoms and a —SO 3 M group and/or a OSO 3 M group (M: counter ion) in its molecule.
