Dibutyl sebacate

Dibutyl sebacate (CAS 109-43-3), commonly abbreviated as DBS, is an ester-based plasticizer and lubricant derived from sebacic acid. It functions as a low-temperature plasticizer and synthetic lubricant base. This versatile chemical serves as a flavoring agent across food, polymer, and industrial applications. In polymer processing, DBS plasticizes PVC, nitrocellulose, and synthetic rubbers to improve flexibility.

It enhances cold-temperature performance in films, coatings, and cable jacketing. Food manufacturers use it as a flavoring ingredient under FEMA 2373, where it contributes fruity, fatty notes. It is frequently utilized in confectionery, beverages, and dairy formulations. In lubricant and metalworking formulations, it performs as a base fluid or additive where low-viscosity stability is required.

Personal care manufacturers incorporate DBS as an emollient and skin-conditioning agent. It is commonly found in creams, lip products, and various color cosmetics for its unique performance properties. Dibutyl sebacate is supplied as a clear, low-viscosity liquid in drum and IBC quantities. Standard grades include food-grade and technical-grade, with food-grade material produced to FCC specifications.

These specifications ensure safety for use in flavor and food-contact applications. Technical-grade material is available for industrial plasticizer and lubricant use where food compliance is not required.
