Novel silicone compounds containing a siloxane moiety and at least one terpenyl moiety, such as limonenyl or valencenyl, and methods for their synthesis, are provided. The novel compounds are appropriate for incorporation into cosmetic formulations due to their low aroma, resistance to deterioration, and favorable solubility properties.

Silicones derived from 2-propenyl functional cyclic terpenes and methods of preparation

The invention includes a fixed-bed catalyst complex that includes (i) a metal carbene catalyst, wherein the metal is platinum, and (ii) a catalyst support that includes one or more of silica, alumina and/or glass. The invention provides a fixed-bed catalyst complex that includes a catalyst complex including a carbene chosen from those represented by at least one of Formulae (I), (II), (III), and (IV): Where the vales of X and Rto Rare specifically defined. The complex also includes a catalyst support that comprises silica, related reaction products, and related reaction systems.

Fixed-bed hydrosilylation catalyst complexes and related methods

The Direct Synthesis of trialkoxysilane is carried out by conducting the Direct Synthesis reaction of silicon and alcohol, optionally in solvent, in the presence of a catalytically effective amount of Direct Synthesis catalyst and an effective catalyst-promoting amount of Direct Synthesis catalyst promoter, said promoter being an organic or inorganic compound possessing at least one phosphorus-oxygen bond.

Process for the direct synthesis of trialkoxysilane

This invention discloses a process to improve reaction stability in the Direct Synthesis of trialkoxysilanes. The process is particularly effective in the Direct Synthesis of triethoxysilane and its higher alkyl cognates providing improved triethoxysilane yields.
