Abstract:
1. A liquid fabric treatment composition, comprising: (a) a cationic fabric softening agent present in an amount of from 2 to 75%; (b) a water-soluble linear polymeric viscosity modifier represented by the formula: in which: X represents a polyether chain, each Y independently represents a linking group derived from a diisocyanate, each Z independently represents a hydrophobic group that is an aliphatic group having from 11 to 24 carbon atoms and optionally includes a spacer linked to Y, wherein said spacer is ethoxy, propoxy or ethylene glycoxy, n represents an integer of at least 2, and the molecular weight of the polymeric viscosity modifier is from 2,000 to 80,000; (c) from 0.3 to 2% by weight of a fatty alcohol or fatty acid containing from 8 to 22 carbon atoms; and (d) from 0.01 to 10% by weight of a nonionic surfactant.
