A method of obtaining fine-grained, free-flowing powdered silicone resins is disclosed. The powdered silicone resins contain very low or no residual aromatic solvents or other volatile organic compounds. The method includes the steps of (1) preparing a solution of an MQ silicone resin dissolved in a volatile liquid organosilicon solvent, such as hexamethyldisiloxane, and (2) spray-drying the solution obtained in step (1) to produce the silicone resin powder.

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.

The present invention relates to a process for preparing clear and colorless alkoxysilane monomers from the reaction of a silazane with an organic alcohol in the presence of an inorganic acid catalyst. The inorganic acid catalyst is present in a critical range from 20 parts per million (ppm) to 300 ppm. Inorganic acid catalysts used within this critical range eliminate the need for a purification step in the process.

The fabric softening agent is a silicone fabric softening agent which is free of aminosubstitution selected from the group consisting of a polyorganosiloxane which is free of reactive organic functional groups and having a viscosity in excess of about 5,000 centistrokes measured at twenty-five degrees Centigrade; a polydiorganosiloxane gum having a viscosity of about two million centistrokes; or a mixture of the said gum with either a low viscosity polydiorganosiloxane or with a volatile cyclic silicone such as octamethylcyclotetra-siloxane or decamethylcyclopentasiloxane. Certain emulsions of a highly branched and cross-linked silicone polymer may also be employed.
