  • Patent number: 5807921
    Abstract: This invention relates to an aqueous silicone emulsion which forms a silicone elastomer upon the removal of water having improved adhesions to substrates. The silicone emulsion comprises the product form by mixing a diorganosiloxane polymer, water, surfactant, optionally a crosslinker, a tin condensation catalyst, optionally an acid and an effective amount of an aminofunctional siloxane which is formed by reacting an aminofunctional silane and a hydroxy-endblocked organosiloxane.

  • Patent number: 5665804
    Abstract: The viscosity of a solvent is modified by thickening the solvent with a silicone latex. A silicone latex having a plurality of crosslinked polysiloxane particles is first prepared by mixing the siloxane polymer, a surfactant, and water; emulsifying the mixture to a gel phase; diluting the emulsion with water; adding a cure package (i.e., a catalyst, a crosslinker, or both, or a self catalytic crosslinker); and then without removing the water from the latex and after the particles of siloxane polymer in the latex have been cured, mixing the latex and solvent to thicken the solvent, forming viscous liquids, gels, and pastes. These latex thickened solvent compositions have beneficial properties such as clarity, shelf stability, and ease of preparation; and therefore have wide areas of application, especially as additives in antiperspirants, deodorants, and other personal care applications.
