| abstract |
The present invention relates to a fabric-softening composition, comprising a cationic fabric softening agent and a thickening polyurethane resulting from the condensation:n a) of at least one compound of formula (I): nn R—[(OE) m -(OP) n —(OB) p ]—OH (I)n in which: R is a saturated or unsaturated, linear or branched carbon chain, containing from 17 to 24 carbon atoms, [(OE) m -(OP) n —(OB) p ] represents an alkoxyl chain formed from alternating or statistical alkoxyl units, distributed in blocks, chosen from ethoxyl units OE, propoxyl units OP and butoxyl units OB and m, n and p represent, independently of each other, 0 or an integer ranging between 1 and 30, the sum of m, n and p being between 20 and 30, b) of at least one polyol, for example of at least one poly(alkylene glycol) and c) of at least one polyisocyanate. |
