A METHOD OF PREPARING FABRIC CONDITIONING COMPOSITIONS |
摘要 |
A method of preparing an aqueous dispersion of a fabric conditioning composition comprises mixing 7.5 to 60 % byweight of a cationic fabric softening compound, the compound having one or more hydrocarbyl chains forme d from parent fatty acyl compounds or fatty acids having an iodine value of fr om 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 provid e a composition having a viscosity of from 10 to 250 mPa.s measured at 20s-1 using a Haake MV1 Rotoviscometer at 20 ~C.
