  • Use of selected polydiorganosiloxanes in fabric softener compositions
    Patent number: 6358913
    Abstract: The invention relates to the use of fabric softener compositions comprising: (a) as active substance, a quaternary ammonium compound of formula (1), in which R is the aliphatic radical of tallow fatty acid, in particular a mono- or polyunsaturated aliphatic C17 radical; and (b) is a nitrogen-free polydiorganosiloxane having terminal silicon-bonded hydroxyl groups; for the treatment of textile fibre materials. The fabric softener compositions impart a soft handle to the treated textile and are readily biodegradable.
