Abstract: A water-based treatment agent for tissue paper suppresses any feeling of slipperiness or wetness in ordinary tissue paper and toilet paper so the paper has a dry touch, ample smoothness, and a clean, smooth, tactile impression. It also provides the paper with a superior softness. The water-based treatment agent consists of a silicone oil emulsion in which crosslinked silicone particles with a mean particle size of 0.01-100 &mgr;m are contained in silicone oil droplets with a mean particle size of 0.05-500 &mgr;m, which are dispersed in water. The particle size of the crosslinked silicone particles is smaller than the particle size of the silicone oil droplets.

Abstract: A silicone oil-in-water emulsion containing a linear noncrosslinked silicone copolymer is prepared by polymerizing an OH endblocked polydimethylsiloxane monomer with an amine functional trialkoxysilane monomer in the presence of a metal catalyst. However, the polymerization is interrupted by the emulsification of this copolymer, and a carboxylic anhydride is added prior to the emulsification. The resulting emulsions are particularly useful in most personal care applications, and they also have value in textile fiber treatment, leather lubrication, fabric softening, as release agents, in water based coatings, for oil drag reduction, lubrication, and for the facilitation of cutting of cellulose materials.

Abstract: An emulsion containing particles of an organopolysiloxane is prepared by (i) combining a silanol endblocked siloxane, an alkyltrialkoxysilane, water, and a nonionic surfactant or an anionic surfactant; (ii) emulsifying these ingredients by agitating these ingredients or by using a high shear device; (iii) adding a condensation specific acid catalyst to the emulsion; (iv) polymerizing the catalyzed emulsion to form an organopolysiloxane polymer; and (v) continuing polymerizing step (iv) until the resulting organosiloxane polymer has the desired viscosity. Organosiloxane polymers exhibiting improved release properties can be obtained by using alkyltrialkoxysilanes R′Si(OR″)3 where R′ and R″ each represent alkyl groups, and R′ contains at least eight, preferably at least twelve, and most preferably at least sixteen or more carbon atoms.
