Abstract
A softener composition comprises (a) 7 to 30 wt. % of a neutralization product with an inorganic or organic acid having not more than 6 carbon atoms of one selected from the group consisting of (a-1) an amine compound having 2 or 3 hydrocarbon groups each having 11 to 22 carbon atoms in its molecule and (a-2) an ion complex compound formed from 1 mole of a polyamide having a hydrocarbon group having 11 to 22 carbon atoms and 2 to 5 nitrogen atoms and 1 mole of an aliphatic acid having 12 to 22 carbon atoms and (b) 0.2 to 5 wt. % of one or more polyethers, each being an adduct of an alkylene oxide including ethylene oxide to a compound having 3 or more active hydrogens, which contains 50 wt. % or more of the polyoxyethylene units, having a molecular weight of 5,000 to 2,000,000. It is of the concentrated type and provides clothing with an improved softness and anti-static property.
