Abstract:
A method of improving the viscosity stability upon storage at temperatures of 25.degree. C. or more but below 40.degree. C. of a fabric softening composition comprising:(a) 8 to 50% by weight of a cationic fabric softening agent; and(b) 0.25 to 2.5% by weight perfume;by inclusion of 5.0% to 15% by weight of an emulsified silicone, based upon the total amount of the composition, which has been emulsified with one or more cationic surfactants to form a macro-emulsion, with the viscosity of the silicone before emulsification being from 10,000 cSt to 400,000 cSt.
