Silicone oil is a linear polymer that is available in a wide range of average kinematic viscosities. It is highly soluble in organic solvents such as aliphatic and aromatic hydrocarbons, and the halocarbon propellants used in aerosols. The fluid is easily emulsified in water with standard emulsifiers and normal emulsification techniques. However, it is insoluble in water and many organic products.

To achieve optimal results in terms of ease of application and depth of gloss, it is preferable to use a blend of low-viscosity and high-viscosity fluids with viscosities ranging from 100 to 30,000cst. The low-viscosity fluid acts as a lubricant to make the polish application and rubout easier, while the high-viscosity fluid produces a greater depth of gloss. These inherently water-repellent polymers cause water to bead up on a treated surface, rather than penetrate the polish film.
