Softener composition

A softener composition comprising (a) 3 to 50 percent by weight of a tertiary amine and/or a salt thereof, having an ester and/or an amide and at least one alkyl or alkenyl having 10 to 22 carbon atoms, and at least one of

• 0.1 to 15 percent by weight of the compound represented by the formula (1),
• wherein R1 represents a C5-12 alkyl or alkenyl group, R2 and R3 independently represent a C1-3 alkyl or hydroxyalkyl group and X is —COO—, —OCO—, —CONH, —NHCO—,
• or a linkage, R4 represents a C1-3 alkylene group, R5 represents a C1-6 alkylene group or —(O—R7)n—, R7 is ethylene group or propylene group and n is a number of 1 to 10;
• and W− is an anionic group;
• 0.1 to 15 percent by weight of the compound of formula (2):
• wherein R6 is a C5-12 alkyl or alkenyl group and W− is an anionic group;
• or
• 0.01 to 15% by weight of a compound represented by formula (3):
• wherein two or three of R8, R9, R10 and R11 are a C8-12 alkyl, the remainders of them are a C1-3 alkyl, a C1-3 hydroxyalkyl or an arylalkyl having 7 to 15 carbon atoms and Z− is an anionic group.
