What is Diethyl adipate?
Diethyl adipate (CAS 141-28-6), commonly abbreviated as DEA, is a diester ester used as a solvent, plasticizer, and emollient carrier. Also known as ethyl adipate.
Where is Diethyl adipate used?
- Personal care: emollient and solvent carrier in skin creams, hair oils, and color cosmetics, improving spreadability without a heavy or greasy residue
- Food: flavoring agent and solvent for flavor concentrates with a mild, fruity character
- Lubricants: synthetic base fluid or co-solvent in metalworking fluids and light-duty lubricants where biodegradability is a primary requirement
- Coatings and polymer processing: plasticizer solvent where low-temperature flexibility is needed
- Its low viscosity and good solvency make it a practical base for skin-compatible fluids.
Commercial specifications
- Purity levels of 99%+ are standard
- Clear liquid in drum and IBC quantities
