Abstract
A concentrated softening agent for use in clothings comprising, as the essential ingredient: PA1 (a) from 10 to 20 by weight of one or more of quarternary ammonium salts, PA1 (b) from 0.5 to 3% by weight of an alkylene oxide addition 10-50M product containing, as an essential ingredient, ethylene oxide of an unsaturated or branched alcohol with 12 to 24 carbon atoms, or an unsaturated or branched alliphatic acid with 12 to 24 carbon atoms, PA1 (c) from 0.5 to 2.0% by weight of a monohydric alcohol with 1 to 3 carbon atoms, PA1 (d) from 3 to 15% by weight of a di- or tri-valent polyol with 2 to 3 carbon atoms, PA1 (e) from 0.05 to 0.4% by weight of an inorganic salt, and PA1 (f) from 0.3 to 5% by weight of one or more of polyether compound or derivative thereof which is prepared by adding an alkylene oxide containing, as the essential ingredient, ethylene oxide to a compound having three or more active hydrogen atoms, in which the total weight for the polyoxyethylene chain moiety is more than 60% by weight of the entire weight and having a molecular weight is from 5,000 to 2,000,000.
