Abstract
An aqueous fabric conditioning composition comprises (a) 7.5 to 60% by weight of a cationic fabric softening compound of a quaternary ammonium softening compound, the compound having one or more hydrocarbyl chains formed from parent fatty acyl compounds or fatty acids having an iodine value of between 0 and 20, (b) 0.01%–1.5% by weight of a nonionic surfactant viscosity modifier and (c) optionally up to 1.4% by weight of a fatty alcohol wherein the combination of (b) and (c) is no more than 1.5% by weight of the composition and the composition comprises particles having a mean diameter of from 0.3 to 7 microns, measured using a Malvern Mastersizer.
