Title: Fabric softening compositions containing emulsified silicone

Abstract: A fabric softening composition comprising: (a) a cationic fabric softening compound; and (b) an emulsified silicone. In one aspect the viscosity of the silicone before emulsification is from 10,000 cSt to 1,000,000 cSt, preferably from 30,000 cSt to 750,000 cSt, more preferably from 40,000 cSt to 400,000 cSt, most preferably 45,000 cSt to 250,000 cSt, eg 45,000 cSt to 200,000 cSt and the emulsion is a macro-emulsion. In another aspect, the median silicone droplet size in the emulsion is at least 0.2 .mu.m, preferably at least 0.25 .mu.m, more preferably at least 0.39 .mu.m, preferably also no greater than 25 .mu.m and is emulsified with an emulsifier comprising one or more cationic surfactants.
