Isononyl Isononanoate is a classic lightweight synthetic ester oil widely adopted in the global cosmetic industry, famous for its unique silk-like skin feel. Different from traditional greasy cosmetic oils, it has ultra-light texture, excellent spreadability and non-sticky finish. It can form a breathable protective film on the skin surface to lock moisture, improve dry and rough skin, and endow skin with soft, smooth and delicate touch. With stable chemical properties, good oxidation resistance and high safety, it can perfectly modify the texture of creams, lotions and color cosmetics, avoiding greasy and heavy feeling. It is an essential texture modifier and emollient raw material for high-end light skincare and makeup formulas.
