Dibutyl adipate

Dibutyl adipate (CAS 105-99-7) is a diester of adipic acid and n-butanol, commercially available under trade names including Cetiol B and Adimoll DB, and abbreviated as DBA or 3PS. It carries no assigned E-code and is classified under HS code 29171200.

In personal care formulations, dibutyl adipate functions as an emollient and solvent by reducing interfacial tension between skin lipids and formula components, improving spreadability and active delivery. In food applications it serves as a flavoring carrier and plasticizer, while in metalworking lubricants it provides film-forming lubrication that reduces friction between metal surfaces under moderate load conditions.

Dibutyl adipate is supplied in cosmetic and food-grade forms meeting FCC and REACH compliance requirements. It is handled as a liquid and typically offered in drums or intermediate bulk containers. Buyers should confirm grade specification against intended application, as purity thresholds differ between food and industrial uses.
