2-Ethylhexyl octanoate is primarily used in cosmetic and personal care formulations as an emollient and solvent, offering a light, non-greasy feel, good spreadability, and skin-conditioning properties with low irritation potential. It is commonly incorporated into creams, lotions, sunscreens, and other skincare products. Additionally, it functions as a plasticizer in select polymer applications to enhance flexibility and low-temperature performance, and in paints and printing inks to improve flow, adhesion, and environmental stability. Its low volatility supports long-term durability in these uses.
