Abstract: Compounds of the formula ##STR1## in which R is an alkyl radical having from one to six carbon atoms, a benzyl radical C.sub.6 H.sub.5 CH.sub.2 --, or the radical --(CH.sub.2).sub.2 OH; X.sup.- is halogen selected from the group consisting of chloride, bromide, and iodide, or CH.sub.3 OSO.sub.3 ; and y is an integer having a value of from four to eleven. The compounds have utility as fabric softening and fabric conditioning agents.

Abstract: Cyclic organosiloxanes which contain at least one Si-bonded organic radical and have at least one donor/acceptor .pi.-electron system.
