Abstract: A method of entrapping a water-soluble substance in vesicles formed from a siloxane surfactant is carried out by dissolving the substance to be entrapped in water, adding a siloxane surfactant, mildly agitating the mixture, and removing excess of water and substance. Water-insoluble substances can be entrapped in the vesicles by dissolving the substance to be entrapped in the siloxane surfactant, and mildly agitating the substance and the siloxane surfactant. Suitable siloxane surfactants are R--[Si(Me).sub.2 O].sub.14 --Si(Me).sub.2 --R in which R is --(CH.sub.2).sub.3 (OCH.sub.2 CH.sub.2).sub.7 OH, R--[Si(Me).sub.2 O].sub.14 --Si(Me).sub.2 --R in which R is --(CH.sub.2).sub.3 (OCH.sub.2 CH.sub.2).sub.12 OH, Me.sub.3 SiO[Si(Me).sub.2 O].sub.22 --[SiMeRO].sub.2 --SiMe.sub.3 in which R is --(CH.sub.2).sub.3 (OCH.sub.2 CH.sub.2).sub.12 OH, and Me.sub.3 SiO[Si(Me).sub.2 O].sub.103 --[SiMeRO].sub.10 --SiMe.sub.3 in which R is --(CH.sub.2).sub.3 (OCH.sub.2 CH.sub.2).sub.12 OH.

Abstract: There is disclosed a method for foam control wherein the antifoam agent is an emulsion gelled silicon composition prepared by first dispersing a curable liquid organopolysiloxane composition in a liquid continuous phase to form an emulsion and then curing the liquid silicone organopolysiloxane in-situ to a gelled state. Preferred compositions of the present invention find particular utility in the control of foam in aqueous detergent systems.

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.
