Abstract: An invention is disclosed which comprises siloxane-based polyamides as gelling agents for cosmetic products, methods for making such agents, formulations thereof and cosmetic formulations therewith. These polyamides contain siloxane groups in the main chain and act to thicken compositions containing volatile and/or non-volatile silicone fluids.

Abstract: Poly(siloxane-acrylate) elastomers with low weep characteristics are formed by the steps of: (A) forming an amine functional alkenyl-containing siloxane by mixing and heating: (a) a polydiorganosiloxane, (b) an amino-functional silane hydrolyzate, (c) an alkenylorganosiloxane, and (d) a base equilibration catalyst, then (B) reacting, at room temperature, the amine functional alkenyl-containing siloxane with an acrylate to form a curable alkenyl-containing poly(siloxane-acrylate) with oxycarbonylethyleneimino-containing organic groups, and (C) curing the alkenyl-containing poly(siloxane-acrylate) to form an poly(siloxane-acrylate) elastomer.

Abstract: An amine-, polyol-, amide-, dimethyl-functional siloxane copolymer and a method for its preparation are disclosed. The copolymer is suitable for use in fiber treatment compositions. The copolymer provides good hand, resistance to yellowing, and hydrophilicity to fibers treated therewith.

Abstract: A fiber treatment composition is disclosed. The composition contains siloxanes having amine-, polyol, and amide-functionalities. The composition provides good hand, resistance to yellowing, and hydrophilicity to the fibers. The composition is preferably formulated as an aqueous emulsion. Applying the composition to textile fabrics produces treated fabrics having good hydrophilicity, good hand, and resistance to yellowing.

Abstract: A fiber treated with a treating agent which is the reaction product of a polysiloxane having at least one aminofunctional group substituted on a silicon atom and having at least one hydrogen--nitrogen bond with a monoacrylate polyether. The present treated fiber has good hand, little yellowing, and improved hydrophilicity when compared to fibers treated with convention aminofunctional polyorganosiloxanes.

Abstract: An invention is disclosed which comprises siloxane-based polyamides as gelling agents for cosmetic products, methods for making such agents, formulations therof and cosmetic formulations therewith. These polyamides contain siloxane groups in the main chain and act to thicken compositions containing volatile and/or non-volatile silicone fluids. Cosmetic compositions may be made by adding at least one active ingredient such as an antiperspirant.

Abstract: A method of making siloxane-based polyamides which includes at least one repeating unit represented by the formula ##STR1## wherein X is a linear or branched C.sub.1 -C.sub.30 alkylene chain; Y is a linear or branched C.sub.1 -C.sub.20 alkylene chain; DP is an integer having a value of 10-500; n is an integer having a value of 1-500. The method involves heating an intimate reaction mixture containing an olefinic acid and an organic diamine at a temperature greater than 100.degree. C. and forming an organic diamide; and thereafter reacting the organic diamide with a hydride-terminated polydimethylsiloxane in the presence of a hydrosilylation catalyst to form the siloxane-based polyamide.

Abstract: The present invention relates to radiation curable silicone vinyl ethers and methods for preparing silicone vinyl ethers. More particularly, the present invention relates compositions containing vinyl ether functional silicones and to the preparation and use of silicone vinyl ethers which are curable by addition of photocleavable acids and exposure to ultraviolet or electron beam radiation.

Abstract: The present invention relates to a curable silicone release coating composition comprising a mixture of an organopolysiloxane containing at least two alkenyl groups per compound, an organohydrogensilicon compound, inhibitors having a boiling point of up to 130.degree. C. at atmospheric pressure, inhibitors having a boiling point of at least 170.degree. C. at atmospheric pressure a platinum group metal-containing catalyst, and optionally a diluent. The silicone release coating compositions are stable when stored at room temperature, especially when the composition is used on a coating roll for the production of a thin films. The compositions of this invention also quickly form a cured film having good release properties for adhesive materials at a comparatively low temperatures.
