Application

Dibutyl Sebacate (DBS) provides superior low temperature flexibility properties to a variety of polymers. The low temperature benefits of DBS make it an excellent choice for vinyl food contact films used in refrigeration. It provides excellent compatibility with a range of plastic materials including vinyls, acrylics, nitrile rubber, Buna-n rubber and some cellulosics.

Content analysis

It can be determinated by a non-polar column method in GT-10-4 or by the method I in the ester assay (OT-18). The amount of sample taken was 1 g. The equivalent factor (e) in the calculation is 64.59.

FEMA (mg/kg): soft drinks 4.1; cold drinks 9.1; candy 21; baked goods 41; pudding class 3.2 to 19.

Production method

It is derived by esterification of succinic anhydride and ethanol; It can also be obtained through heating esterification of sebacic acid and ethanol in the presence of concentrated sulfuric acid.

Definition

ChEBI: Diethyl decanedioate is a fatty acid ester. It is the diester of ethyl alcohol and Sebacic Acid that used as an aromatic in food.

Preparation

Diethyl sebacate is obtained by heating sebacic acid and ethanol in the presence of concentrated H2SO4 or other acid catalysts.

General Description

Diethyl sebacate is a volatile organic compoind used as a flavoring agent. It is reported to be found in longan honey porduced by Apis cerana.

Health effects

Diethyl sebacate is reported to be used in cosmetics at 1.5%, and no irritation or sensitization was reported in clinical studies of a formulation containing 1.5% diethyl sebacate.
