Abstract
A method of preparing an aqueous dispersion of a fabric conditioning composition comprises mixing 7.5 to 60% by weight of a cationic fabric softening compound, the compound having one or more hydrocarbyl chains formed from parent fatty acyl compounds or fatty acids having an iodine value of from 0 to 20 with 0.01%–1.5% by weight of a nonionic surfactant viscosity modifier and up to 1.4% by weight of a fatty alcohol, the combination of (b) and (c) being no more than 1.5% by weight, based on the total weight of the composition, the aqueous dispersion being subjected to high-shear below the phase transition temperature of compound (a) for a time sufficient to provide a composition having a viscosity of from 10 to 250 mPa·s measured at 20 s−1 using a Haake NV1 Rotoviscometer at 20° C.
