Description
Diethyl phthalate (DEP, CAS 84-66-2) is a phthalate ester solvent commercially known under trade names including Anozol, Phthalol, and Solvanol. It carries no assigned E-code and is identified under EC number 201-550-6 with the molecular formula C12H14O4.
In personal care formulations, DEP functions as a solvent and fixative for fragrance compounds, slowing evaporation rates to extend scent longevity. In plastics processing, it acts as a plasticizer by intercalating between polymer chains to reduce brittleness, and in printing inks it serves as a carrier solvent controlling viscosity and drying behaviour.
DEP is supplied as a liquid and is available in industrial and cosmetic-grade specifications, with procurement governed by REACH registration requirements within the EU. Buyers should note its classification status under current ECHA guidance before specifying for new formulations. Standard packaging includes drums and IBC containers, with documentation available on request.
