Dibutyl sebacate, dibutyl sebacate also, is a colorless, odorless, oily organic chemical compound, the diester of sebacic acid with the alcohol 1-butanol. Dibutyl sebacate has a wide range of applications as plasticizers in plastics, additives in cosmetic and skin care products as well as part of sustained-release hard gelatin capsules for pharmaceuticals.

Representation

Dibutyl sebacate can be prepared by acid-catalyzed esterification of sebacic acid with 1-butanol.

Use

Dibutyl sebacate is mainly used as plasticizers for plastics, and plastic films, but also in many cosmetic products, include skin and hair care cosmetics, and pharmaceutical capsules. Dibutyl sebacate may be included because of its low toxicity in food packaging. Furthermore, it acts film-forming and as retardants, which is why it is mixed explosives and highly reactive fuels such as fuel Otto 2 in torpedoes.
