  • Patent number: 5091105
    Abstract: A liquid detergent having fabric softening properties and including an improved fabric softening agent. The fabric softening agent is a silicone fabric softening agent which is free of aminosubstitution selected from the group consisting of a polyorganosiloxane which is free of reactive organic functional groups and having a viscosity in excess of about 5,000 centistrokes measured at twenty-five degrees Centigrade; a polydiorganosiloxane gum having a viscosity of about two million centistrokes; or a mixture of the said gum with either a low viscosity polydiorganosiloxane or with a volatile cyclic silicone such as octamethylcyclotetra-siloxane or decamethylcyclopentasiloxane. Certain emulsions of a highly branched and cross-linked silicone polymer may also be employed.
    Type: Grant
    Filed: January 7, 1991
    Date of Patent: February 25, 1992
