Diethyl adipate

Diethyl adipate (CAS 141-28-6), commonly abbreviated as DEA, is a diester ester used across cosmetic, food, and industrial formulations as a solvent, plasticizer, and emollient carrier. Ethyl adipate is a recognized alternative name in flavor and fragrance sourcing contexts. Its low viscosity and good solvency make it a practical base for formulations requiring skin-compatible fluids.

In personal care, DEA functions as an emollient and solvent carrier in skin creams, hair oils, and color cosmetics, improving spreadability without leaving a heavy or greasy residue on the skin. The food industry uses it as a flavoring agent and solvent for flavor concentrates, particularly in applications requiring an ester with a mild, fruity character for specific aromatic profiles.

In lubricant formulations, it serves as a synthetic base fluid or co-solvent in metalworking fluids and light-duty lubricants where biodegradability is a primary formulation requirement for the user. It also acts as a plasticizer solvent in specialty coatings and polymer processing where low-temperature flexibility is needed. This versatility makes it a staple in modern chemical manufacturing.

Diethyl adipate is supplied as a clear liquid in drum and IBC quantities. Food-grade and cosmetic-grade specifications are the most commonly traded, with technical-grade material available for use. Purity levels of 99%+ are standard across commercial supply chains. Our material meets rigorous quality benchmarks to ensure consistency and performance across all diverse industrial applications.
