Isododecane is a highly branched synthetic hydrocarbon product that is clear, colorless, and odorless, containing almost no aromatic hydrocarbons or sulfur. With an extremely fast evaporation rate, it can completely replace volatile silicone oils. It is water-resistant, sweat-resistant, and suitable for dry skincare and haircare products. It exhibits excellent compatibility, fully dissolving in silicone oils, mineral oils, other hydrocarbons, and isoparaffins. With low density and low viscosity, it offers a lightweight oily feel, enhances skin compatibility and oil solubility, and improves product spreadability and application feel.
