Isododecane is a synthetic hydrocarbon ingredient commonly used in cosmetic formulations. It is a colorless, odorless, and volatile liquid that has a lightweight and non-greasy texture. Its primary use cases in cosmetic formulations include:1. Solvent: Isododecane acts as a solvent for various ingredients, helping them dissolve and mix well in the formulation. This ensures a smooth and even application of the product on the skin.2. Texture enhancer: Due to its lightweight and non-greasy nature, Isododecane improves the texture of cosmetic products, making them easy to spread and absorb into the skin.3. Evaporative agent: Isododecane evaporates quickly, leaving behind a dry, matte finish on the skin. This makes it an ideal ingredient for matte makeup products, such as foundations, lipsticks, and eyeshadows.4. Film-former: Isododecane forms a thin, flexible film on the skin, which helps in providing long-lasting wear and water resistance to makeup products.5. Emollient: Although not as moisturizing as other emollients, Isododecane can help to soften and smooth the skin, providing a comfortable feel in cosmetic products.Overall, Isododecane is a versatile ingredient that enhances the performance, texture, and wear of various cosmetic products, including makeup, skincare, and hair care products.
