A novel saccharide siloxane copolymer has improved stability in the presence of water as compared to certain previously known saccharide siloxanes. The saccharide siloxane copolymer is useful in personal care compositions.

Saccharide siloxanes stable in aqueous environments and methods for the preparation and use of such saccharide siloxanes

There are disclosed novel quaternary ammonium functional silicone based emulsions and other formulations, as well as methods to make such emulsions and formulations. These materials have uses in personal care and other applications.

Silicon based quaternary ammonium functional compositions and their applications

A composition for rendering surfaces water repellent is formed by combining water or a solvent; a methylhydrogensiloxane polymer or copolymer; an alkoxysilane having the formula R Si(OR&prime;) in which R represents an alkyl group containing 1-10 carbon atoms, an alkenyl group containing 2-8 carbon atoms, an aryl group, or an haloalkyl group, a has a value of 1 or 2, and R&prime; represents an alkyl group containing 1-6 carbon atoms; and a silicone resin. The composition can also contain other components such as a volatile methyl siloxane, a cationic oil-in-water emulsion of an aminofunctional polydimethylsiloxane, a surfactant, a catalyst, a beading agent, an organic wax, a preservative, an antifoam, a mildewcide, an UV absorber/UV light stabilizer, or a freeze-thaw additive.
