Abstract: A cosmetic composition comprising an aqueous emulsion of organopolysiloxanes selected from the group consisting of silicone oils, gums, resins and mixtures therein which is prepared in a single kneading step which is sufficient to produce an emulsion having a particle size of 0.1 to 5 micrometers is provided.

Abstract: Aqueous silicone dispersions crosslinkable into elastomeric state by elimination of water therefrom, well adapted for the production of elastomer seals, e.g., for the building industry, include:(A) 100 parts by weight of an oil-in-water emulsion of an .alpha.,.omega.-(dihydroxy)polydiorganosiloxane stabilized with at least one anionic or nonionic surface-active agent, or mixture thereof;(B) 1 to 100 parts by weight of an hydroxylated silicone resin containing, per molecule, at least two different recurring structural units selected from among those of the formulae: R.sub.3 SiO.sub.0.5, R.sub.2 SiO, RSiO.sub.1.5 and SiO.sub.2, wherein the radicals R, which may be identical or different, are vinyl, phenyl or 3,3,3-trifluoropropyl radicals, or linear or branched chain alkyl radicals containing from 1 to 6 carbon atoms, said resin having a hydroxyl group weight content of from 0.1% to 10%;(C) 0 to 250 parts by weight of a nonsiliceous inorganic filler;(D) 0.

Abstract: Aqueous dispersions containing: a silicone oil (A) which is cross-linkable by condensation, optionally in the presence of a cross-linking agent (B), into an elastomer; optionally a cross-linking agent (B), a silane (C) and a mineral filler (D); and a catalytic amount of a hardening compound (E). Said dispersions are characterized in that they are produced by kneading a mixture of (1) a silicone phase (F) with a viscosity of at least 3 Pas, containing the oil (A) and optionally one or more of components (B), (C), (D) or (E), and 2) an aqueous phase comprising water and at least one surfactant (G), wherein the weight ratio water/water+surfactant(s) is such that the viscosity of the aqueous phase is preferably at least as high as that of the silicone phase (F); for a sufficient time and with sufficient shear to give an oil-in-water emulsion having a particle size of 0.

Abstract: A method for preparing oil-in-water emulsions of oils, gums or silicone resins by kneading a mixture of (1) a silicone phase (A) with a viscosity of at least 3 Pas or a consistency of at least 200, and (2) an aqueous phase comprising water, at least one surfactant (B) and optionally at least one water-soluble thickening polymer (C), wherein the relative amounts of water, (B) and optionally (C) are such that the aqueous phase preferably has at least as much viscosity or consistency as the silicone phase (A), said kneading being performed for a sufficient time and with sufficient shear to give an oil-in-water emulsion having a particle size of 0.1-5 .mu.m; and optionally by diluting the medium in water.

Abstract: Thixotropic silicone emulsions crosslinkable into elastomeric state upon removal of water therefrom, e.g., to fabricate elastomer seals for the construction industry, have a pH of from 4 to 8 and a solids content of at least 50%, and contain:(A) 100 parts of an oil-in-water emulsion of an .alpha.,.omega.-(dihydroxy)polydiorganosiloxane, and a stabilizing amount of at least one anionic or nonionic surface-active agent, or mixture thereof;(B) 1 to 15 parts of a siliceous reinforcing filler in powder form;(C) 0 to 250 parts of an inorganic filler other than the siliceous filler (B);(D) 0.01 to 2 parts of a catalytic tin compound; and(E) 0.1 to 5 parts of boric oxide, a boric acid or a borate.

Abstract: Provided are single component organopolysiloxane compositions which are hardenable at ambient temperatures and contain as the cross-linking agent silanes with hydrocarbonoyloxy (acyloxy) or ketoniminoxy groups. The compositions further comprise a cross-linking catalyst which is an organic derivative of titanium, e.g., a titanium ester, polytitanoxane, alkanolamine titanate, etc., or an organic derivative of zirconium, e.g., a zirconate, polyzirconate, etc. After cross-linking, the present compositions provide organopolysiloxane elastomers exhibiting good properties.The organopolysiloxane compositions are referred to as "single component" to contrast them with the two-component organopolysiloxane compositions which are not storage stable and must therefore be handled in two separate packages, which problem is overcome by the present compositions.
