  • Patent number: 5468829
    Abstract: A method for preparing in situ reinforced silicone elastomers and the compositions prepared by the method. The method comprises forming a mixture comprising an end-functional diorganopolysiloxane; a stoichiometric excess of a hydrolyzable siloxane having hydrolyzable functionality described by formula--R.sup.2 SiQ.sub.3-b R.sub.b, were each R is independently selected from a group consisting of alkyls comprising one to six carbon atoms, alkenyls comprising two to six carbon atoms, and aryls, R.sup.2 is a divalent hydrocarbon radical comprising one to 12 carbon atoms, each Q is independently selected from a group consisting of hydroxy, acyloxys comprising one to six carbon atoms, alkoxys comprising one to six carbon atoms, and substituted alkoxys comprising one to six carbon atoms, and b=0 to 2; and a tin salt catalyst and contacting the mixture with water to effect curing. The resulting silicone elastomers are in situ reinforced to provide high strength.

  • Patent number: 5413781
    Abstract: A method of treating human skin to decrease transepidermal water loss. A film forming conditioning formulation which includes as an ingredient thereof an organosilicon compound is applied to the skin. The improvement resides in the utilization of a formulation which is dimethylpolysiloxane free and which includes as the organosilicon compound an alkylmethyl polysiloxane.

  • Patent number: 5395908
    Abstract: A method for preparing in situ reinforced silicone elastomers and the compositions prepared by the method. The method comprises forming a mixture comprising a diorganosiloxane polymer having reactive end-terminal functionality, a stoichiometric excess of a reactive siloxane selected from a group consisting of triorganosilyl endblocked reactive siloxanes and reactive cyclosiloxanes, and a tin salt catalyst and contacting the mixture with water to effect curing. The resulting silicone elastomers are in situ reinforced to provide high strength.

  • Patent number: 5389364
    Abstract: Hair is conditioned by applying to the hair an effective amount of a composition which includes as the hair conditioning agent, from 0.5 to 5.0 percent by weight of a derivatized amine functional organosilicon compound which is one of (i) a reaction product of an amine functional polysiloxane and a derivative of carbonic acid; (ii) a reaction product of an amine functional polysiloxane and a lactone; (iii) a reaction product of an amine functional silane and a derivative of carbonic acid; or (iv) a reaction product of an amine functional silane and a lactone.

  • Patent number: 5063044
    Abstract: A hair conditioning composition being a mixture including water, a thickener, and an organosilicon compound is disclosed. Also disclosed is a hair shampoo conditioning composition in the form of a mixture including water, at least one surfactant, a thickener, and an organosilicon conditioning compound. In both compositions, the organosilicon compound is a siloxane selected from the group consisting of carboxy functional polysiloxanes, carboxy-glycol ether functional polysiloxanes, and carboxy-glycol ester functional polysiloxanes. These compositions may also include dyes, neutralizing agents, or reducing agents, if desired.
