Organosilicone

Low surface tension enables Vertasil® TM-L01 Limonenyl Trisiloxane and Caprylyl Methicone to spread easily on the skin. As a result, these fluids modify the feel and reduce the tack of materials such as natural butters and oils, as well as synthetic and petroleum based products. They exhibit the typical silicone " slip " and provide a non-greasy, silky soft after feel. An in-house study was conducted comparing the sensory experience of a 1:1 blend of Limonenyl Trisiloxane or Caprylyl Methicone in common cosmetic and personal care ingredients. Overall, 41% of panelists Limonenyl Trisiloxane and Caprylyl Methicone share similar solubility characteristics permitting compatibility with common raw materials including natural oils and waxes, hydrocarbons, esters, and UV absorbers. Both fluids can be used as co-solubilizers in formulations containing oil-insoluble fluids such as dimethicones.

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 deteriora tion, and favorable solubility properties.

The invention relates to silicon compounds having formula (I): (RfCH.sub.2CH.sub.2).sub.2-n[R(OCH.sub.2CHR').sub.mOR''].sub.nSiX.sub.2 (I). In formula (I), Rf is a linear or branched perfluorinated hydrocarbon having 4 or more carbon atoms, R is a methyl or ethyl group, R' is H or CH.sub.3, m is an integer of 1 to about 24, R'' is a hydrocarbon bridge having 1 to about 11 carbon atoms, n is an integer from 0 to 2, and X is H, Cl or an alkoxy group. The inventive materials may be used to produce siloxanes or silicones by hydrolytic condensation and have utility in surface modification.

Silicon-based cannabidiol derivatives and methods for their synthesis are provided, in which the derivatives contain a cannabidiol molecule and at least one silicon-based group containing Si--O--Si bonds. The derivatives are useful in cosmetic and topical compositions, have potential beneficial topical properties, and enhance solubility and compatibility in cosmetic formulations containing the silicon-based materials. Silicone elastomers infused with compositions containing the silicon-based cannabidiol derivatives and trisiloxanes are also provided.

A stabilized mixture containing an alkyltrialkoxysilane hydrolysate solution and an amine functional silicone emulsion is provided. The stabilized mixture may be utilized in a masonry treatment product or a cellulosic or wood treatment product, such as to provide waterproofing properties, or in a hair care treatment product for improving hair combability. A method of preparing the mixture involves hydrolyzing an alkoxysilane to form an aqueous solution containing alkylsilanetriols and/or oligomeric alkylsilanetriol condensates; and stabilizing the solution by adding an amine functional silicone.
