Abstract: The present invention relates to a novel use of nanomaterials as a viscosity modifier and thermal conductivity improver for gear oil and other lubricating oil compositions. The gear oils of the instant invention have a higher viscosity index, higher shear stability, and improved thermal conductivity compared to currently available gear oils. The preferred nanoparticles also impart a reduction in the coefficient of friction, including reduced friction in the boundary lubrication regime. These properties are obtained by replacing part or all of the polymer thickener or viscosity index improver or some other part of the composition normally used in gear oils with nanomaterials of suitable shape, size, and composition.

Abstract: The present invention provides a liquid protectant composition composed of a cationic microemulsion of a natural wax (carnauba wax) nanometer sized particles and zinc oxide nanometer sized particles in combination with a quaternary siloxane compound. The protectant composition of the present invention cleans, protects preserves and enhances the appearances of leather or vinyl surfaces used for covering items in the home or in vehicles. The product is easy to apply to both smooth and textured surfaces and has a transparent appearance. The product dries quickly and does not leave an oily residue. Utilization of nano technology to select components having nano sized particles provides a uniform deposition of the product leaving a thin film having exceptional protection properties. Unlike conventional protectants, the invention of the instant composition dries quickly and leaves no oily residue behind.

Abstract: A wax composition for application to a wet surfaces utilizing a polymeric emulsion with a cross-linked copolymer of acrylic acid and C10-30 alkyl acrylate whereby upon application to the surface to be waxed the hydrophilic portion of the polymer instantly collapses releasing the oil phase and providing immediate coverage of the application surface forming a film upon drying, and buffing the waxed surface with an absorbent material leaves a protective coating of wax of the surface which does not easily re-emulsify or wash off when further exposed to water.
