Abstract: An aqueous dispersion includes precrosslinked organopolysiloxanes, emulsifiers, and water. The precrosslinked organopolysiloxanes include units of the formula R2SiO2/2 (I), and on average at least one structural unit of the formula SiR1O2/2—Y—SiR1O2/2 (III) where Y is a divalent radical of the formula —R2—[NR3—R4—]nNR3—C(O)—C(O)—NR3—Z—NR3—C(O)—C(O)—NR3—[R4—NR3—]nR2—.

Abstract: Oil-in-water emulsions containing (i) 100 parts by weight of polyorganosiloxanes bearing aminoalkyl groups, liquid at 20° C., (ii) protonating agent, (iii) 1 to 80 parts by weight of silicate compound, (iv) water, (v) at most 5 parts by weight emulsifier and (vi) at least 5 parts by weight of an organic solvent selected from monoalcohols of the formula IX R11—OH??(IX), and dialcohol monoethers of the formula X R12O—R13—OR14??(X), with the proviso that the emulsion comprises at most 10 parts by weight of a di-, tri- or oligoglycol ether, are useful for treating substrates.

Abstract: Aqueous nanoemulsions of carbamato-functional organopolysiloxanes prepared using a polyoxyethylene emulsifier having an HLB greater than 15 and at least 40 oxyethylene moieties and having a D50 particle size ?100 nm are transparent, stable, and useful in cosmetic compositions, particularly hair care compositions.

Abstract: Compositions containing ?-ketocarbonyl-functional organopolysiloxanes, aminoalkyl-functional organopolysiloxanes, and optionally an organometallic compound provide textiles with high and lasting water repellency.

Abstract: Storage stable aqueous dispersions of ?-ketocarbonyl functional organosilicon compounds are prepared using a non-ionic emulsifier having an HLB of less than 15. The compositions are suitable for treating textiles.

Abstract: Defoamer compositions containing a plurality of defined organopolysiloxanes exhibit very short initial foam collapse and yet exhibit long lasting defoaming activity when added to aqueous media prone to foaming.

Abstract: Defoamer preparations contain a polyorganosiloxane having aryl groups bonded to silicon at a ring carbon, filler particles and/or silicone resin particles, and a polyoxyalkylene polyether containing oxypropylene moieties. In addition to being efficient and compatible, the defoamer compositions retain their efficiency, especially in liquid detergents, after storage.

Abstract: Effective defoamer compositions contain two different aryl-substituted organopolysiloxanes and filler particles, and show high defoaming capability.

Abstract: Emulsions of carbamato-functional organopolysiloxanes emulsified with the aid of cationic emulsifiers are useful for treating textiles to provide good haptic properties, and also in hair care products.

Abstract: Efficient defoamer and foam prevention formulations contain an organopolysiloxane defoamer and an efficiency promoting waxy ?-ketocarbonyl-functional organosilicon compound. The compositions also preferably contain a filler and a silicone resin, and are highly efficient in surfactant-containing aqueous systems such as detergents and cleaners.

Abstract: A mixture of unique organopolysiloxane, filler, and additional components are effective defoamers and may be used neat, or in the form of a powder or emulsion.
