Patent ID: 7189687

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 5.5/4.5: (a) a tertiary amine represented by the formula (1) , or a salt thereof: wherein R 1 represents an alkyl group or an alkenyl group having 15 to 23 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— and —CONH—, “a” denotes a number of 0 or 1; (b) a tertiary amine represented by the formula (3) or a salt thereof: wherein R 10 and R 12 respectively represent an alkyl group or an alkenyl group having 9 to 20 carbon atoms, R 11 and R 13 respectively represent an alkylene group having 1 to 6 carbon atoms, R 14 represents an alkyl group having 1 to 3 carbon atoms, a hydroxyalkyl group or a group represented by the formula R 10 -[D-R 11 ] c —, D and E, respectively represent a group selected from —COO— and — CONH—, “c” and “d” respectively denote a number of 0 or 1; (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; and 30–95 mass % of water.
