Diethyl sebacate

Diethyl sebacate (CAS 110-40-7) is a diester of sebacic acid and ethanol, commercially known under names such as Bisoflex DES, SDE, and FEMA 2376. It carries no E-code designation and is classified under HS code 29171390. The compound belongs to the dicarboxylic acid ester family within the oils, fats, and waxes category.

In food and flavour applications, diethyl sebacate functions as a FEMA-listed flavorant, contributing fatty, fruity top notes at low concentrations. In plasticiser and polymer formulations, it acts as a secondary plasticiser, improving low-temperature flexibility in PVC and similar resins by reducing intermolecular chain rigidity. Personal care formulators use it as a skin-conditioning emollient with low greasiness.

Diethyl sebacate is available in food-grade (FCC-compliant) and technical grades, supplied in drums and IBC containers. It is registered under REACH and complies with relevant EU cosmetic ingredient regulations. Buyers should confirm grade suitability against FCC or Ph.Eur. specifications depending on the intended application.
