Beschreibung
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.
Chemische Eigenschaften
White powder
Verwenden
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.
Allgemeine Beschreibung
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)
Kontakt-Allergie
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.
Sicherheitsprofil
A poison by
intraperitoneal route. Moderately toxic by
ingestion. When heated to decomposition it
emits acrid smoke and irritating fumes.
