Dodecyl Gallate
What is Dodecyl Gallate?
Dodecyl gallate is a synthetic alkyl ester formed from gallic acid, a plant-derived polyphenol, and dodecanol, a fatty alcohol with 12 carbon atoms. It appears as a white to yellowish powder and is widely employed in the cosmetic industry within oil-in-water emulsions, anhydrous products, and lipophilic formulations like balms and foundations. As a phenolic antioxidant, it operates by donating hydrogen atoms to free radicals, interrupting chain reactions of lipid peroxidation, and binding pro-oxidant metal ions such as iron. This mechanism shields polyunsaturated oils, natural extracts, and volatile components from breakdown, ensuring formulation integrity against air, light, and heat exposure. Its hydrophobic structure enables effective distribution in non-aqueous environments, distinguishing it from hydrophilic counterparts for superior protection in fatty matrices.
