DEP is a popular and widely used solvent and fixative for the Essential Oils, Perfumes, Cosmetic, and Agarbathi Industry (Scented Incense Sticks) in India. It is also used as a denaturant for Ethyl Alcohol.

DEP is one of the most used plasticizers for cellulose acetate and other cellulose esters. It imparts clarity, light fastness and good mechanical and physical properties to the cellulose acetate products; moreover it exhibits a low volatility and freezing point.
