Monoethyl sebacate

Monoethyl sebacate (CAS 693-55-0, EC 211-753-1) is a monoester derived from sebacic acid and ethanol, also referenced under the names ethyl hydrogen sebacate, 1-ethyl decanedioate, and NSC 53961. It carries no assigned E-code and belongs to the oils, fats, and waxes chemical category.

In polymer processing, monoethyl sebacate functions as a plasticizer by intercalating between polymer chains to reduce glass transition temperature and improve flexibility in PVC and related resins. In personal care formulations, it acts as a solvent and emollient carrier, solubilising active ingredients while contributing lubricity to skin-contact products. It also serves as a boundary lubricant in metalworking fluids.

Monoethyl sebacate is subject to REACH registration requirements for supply within the European Economic Area. It is available for procurement in standard industrial drum and IBC formats. Buyers should confirm grade specifications and documentation requirements, including SDS and CoA, directly with the supplier.
