Octyl gallate Chemical Properties,Uses,Production
Description
During the 1940s, propyl gallate and several other alkyl gallates were allowed for use in foods in a number of countries. Since gallic acid contains three phenolic hydroxyl groups, it is a rather potent antioxidant; however, the propyl ester has a significant degree of water solubility. As a consequence, propyl gallate tends to partition into any water phase which may be present and to complex with iron salts to give bluish black colors. Also, its relatively poor resistance to heat degradation makes it ineffective for baking and frying applications. The higher alkyl gallates (butyl and octyl) are more fat soluble.
Chemical Properties
White powder
Uses
Octyl gallate is an antioxidant that is used as a preservation agent in a wide variety of foods, oils, and cosmetics.
Definition
ChEBI: A gallate ester obtained by condensation of the carboxy group of gallic acid with the hydroxy group of octanol.
General Description
Octyl gallate is an ester of gallic acid which is generally used as an antioxidant in food and pharmaceutical industries. It can act against the oxidative damage caused by reactive oxygen species (ROS) in the form of hydroxyl radicals or hydrogen peroxides, and reactive sulfur species (RSS)
Contact allergens
Octyl gallate, a gallate ester (E 311), is an antioxidant added to food and cosmetics to prevent oxidation of unsaturated fatty acids. Cases were sparsely reported in food industry or from lipsticks. Patch tests are frequently irritant.
Safety Profile
A poison by intraperitoneal route. Moderately toxic by ingestion. When heated to decomposition it emits acrid smoke and irritating fumes.
