Abstract

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 polyamine 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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 175 words
A concentrated softener comprising (a) 7 to 30% by weight of a neutralization product of one of the following amine compounds with an inorganic acid or an organic acid having not more than 6 carbon atoms: (a-1) amines each having 2 to 3 hydrocarbon groups in its molecule, with each of the hydrocarbon groups having 11 to 22 carbon atoms and (a-2) ion pairs each constituted of a polyamine having 2 to 5 nitrogen atoms and one hydrocarbon group having 11 to 22 carbon atoms and a fatty acid having 12 to 22 carbon atoms at a molar ratio of 1 : 1; and (b) 0.2 to 5% by weight of one or more members selected from among polyether compounds which are each an adduct of a compound having at least 3 active hydrogen atoms with an alkylene oxide component comprising ethylene oxide as an essential component wherein the sum total of the polyoxyethylene chain segments is at least 50% of the whole weight and the molecular weight is 5,000 to 2,000,000, and derivatives thereof.
Claim 2
Dependent Claim 175 words
A concentrated softener comprising (a) 7 to 30% by weight of a neutralization product of one of the following amine compounds with an inorganic acid or an organic acid having not more than 6 carbon atoms: (a-1) amines each having 2 to 3 hydrocarbon groups in its molecule, with each of the hydrocarbon groups having 11 to 22 carbon atoms and (a-2) ion pairs each constituted of a polyamine having 2 to 5 nitrogen atoms and one hydrocarbon group having 11 to 22 carbon atoms and a fatty acid having 12 to 22 carbon atoms at a molar ratio of 1 : 1; and (b) 0.2 to 5% by weight of one or more members selected from among polyether compounds which are each an adduct of a compound having at least 3 active hydrogen atoms with an alkylene oxide component comprising ethylene oxide as an essential component wherein the sum total of the polyoxyethylene chain segments is at least 50% of the whole weight and the molecular weight is 5,000 to 2,000,000, and derivatives thereof.
Claim 3
