Sebacinsäuredi- n -butyl , and dibutyl sebacate , is a colorless, odorless, oily organic chemical compound , the di ester of sebacic acid with the alcohol 1-butanol . Dibutyl sebacate has a wide range of uses as a plasticizer in plastics , an additive in cosmetic and skin care products and a component of sustained - release hard gelatine capsules for pharmaceuticals.

presentation

The compound can be prepared by the acid-catalyzed esterification of sebacic acid with 1-butanol.

properties

The flash point is 178 ° C, the ignition temperature 365 ° C.

use

Sebacinsäuredi- n -butyl is mainly used as plasticizers for plastics, including plastic films is, but also in many cosmetic products, skin and hair care products, cosmetics contain and drug capsules. Dibutyl sebacate may be contained in food packaging due to its low toxicity. It also has a film-forming and phlegmatizing effect , which is why it is mixed with explosive and highly reactive fuels such as Otto 2 in torpedoes .
