Softener composition

A softener composition comprising the following components (A′) and (B′):

• (A′) a cationic surfactant comprising at least one selected from the group consisting of quaternary ammonium salts represented by the formulae (I), (II) or (III)
• and at least one selected from the group consisting of amines or salts thereof represented by the following formulae (V), (VI) or (VII), where the ratio of the total mole number of the quaternary ammonium salts to the total molar number of amines or the salts thereof is 99.9:0.1 to 70:30 and the ratio of the quaternary ammonium salts represented by the formula (I) to the total amount of the quaternary ammonium salts represented by the formulae (I), (II) and (III) exceeds 50 weight % and the ratio of (III) to the sum total of (I), (II) and (III) is not more than 10%:
• wherein R1, R2 and R3 represent a long-chain alkyl or alkenyl group having the total carbon atoms of 8 to 40, which are the same as or different from one another and may be intersected by an ether group, an ester group or an amide group;
• R4 represents an alkyl group, an alkenyl group or a hydroxy alkyl group, having 1 to 6 carbon atoms, plural R4's being the same as or different from one another;
• and X− represents an anionic group;
• and
• (B′):
• at least one nonionic surfactant selected from the group consisting of compounds represented by formulae (VIII) and (IX):
• wherein, R7 represents an alkyl group or an alkenyl group having carbon atoms of 8 to 22, A represents an alkylene group having 2 to 4 carbon atoms, n represents a number of 4 to 100 on the average value, p and q are a number of 1 to 50 on the average value, being the same as or different from each other, and plural A's may be the same as or different from one another;
• and
• wherein, the blending ratio in the softener composition of the component (A′) to the component (B′) by weight, which is (A′)/(B′), is 50/1 to 1/2, and the blending ratio of the component (A′) to the softener composition is 3 to 50 weight %.
