84-66-2
Product name: Diethyl Phthalate
English alias: DEP; Phthalic acid diethyl ester; Ethyl phthalate
CAS: 84-66-2
Molecular formula: C12H14O4
Appearance: Colorless transparent oily liquid
Package: 200 kg/drum, 1000 kg/IBC tank
Diethyl Phthalate is a man-made, colorless, oily liquid with a faint aromatic odor.
It is considered a type of phthalate, which is an ester of phthalic acid.
Diethyl Phthalate (DEP) is a low molecular weight phthalate ester produced by the esterification of phthalic anhydride with ethanol. It is characterized by its low viscosity, high solvating power, and relatively low boiling point. DEP exhibits excellent compatibility with cellulose esters (like cellulose acetate), making it a crucial plasticizer and solvent in specific industrial sectors. Unlike some other phthalates, it has a distinct toxicological profile and is generally subject to fewer regulatory restrictions, particularly in cosmetic and fragrance applications.

1. Primary Use: As a solvent and plasticizer for cellulose acetate in the production of cigarette filter tow, films, and molded articles.
2. Diethyl Phthalate used as a solvent and fixative in perfumery, cosmetics, and personal care products (e.g., hairsprays, nail polishes) to reduce the evaporation rate of fragrance ingredients.
3. Diethyl Phthalate employed as a plasticizer and processing aid for other polymers, including polyvinyl acetate (PVAc) adhesives.
4. It used as a carrier for dyes and pigments.
5. Functions as a denaturant for alcohol.
6. Applied in specialty coatings and lacquers.
DEP has low acute toxicity and is not classified as a reproductive or developmental toxicant based on current major regulatory assessments (e.g., by the EU SCCS, US FDA). It is generally permitted for use in cosmetics and fragrances. However, it may cause mild eye and skin irritation. Prolonged or repeated skin contact should be avoided. Use personal protective equipment including gloves and safety glasses. Ensure adequate ventilation. While its regulatory status is more favorable than many other phthalates, users should always verify compliance with the latest local regulations for their specific application.
Store in a cool, dry, well-ventilated area away from direct sunlight, heat, and ignition sources. Keep containers tightly closed to prevent moisture absorption and evaporation. Recommended storage temperature: 10-40 °C. Store away from strong oxidizing agents, strong acids, and strong bases.
DEP is typically supplied in 200 kg steel or HDPE drums and 1000 kg IBC containers. It is generally classified as non-hazardous for transport. However, specific shipping classification should be verified based on the latest regulations.
