Propyl Gallate

Description

Propyl Gallate is a synthetic antioxidant widely used in cosmetic and skincare formulations to protect products from oxidation and rancidity. This white to creamy-white crystalline powder is an ester of propanol and gallic acid, with the chemical formula C10H12O5. Its primary function is to extend the shelf life of products containing fats and oils by inhibiting the formation of free radicals and preventing lipid peroxidation.

In skincare, Propyl Gallate offers multiple benefits beyond its preservative properties. It acts as a free radical scavenger, helping to protect the skin from oxidative stress and environmental damage. This ingredient can contribute to the overall stability and efficacy of formulations containing sensitive active ingredients.

Propyl Gallate is typically used in concentrations ranging from 0.01% to 0.1% in cosmetic products. It is often found in moisturizers, serums, and anti-aging formulations. While generally considered safe for topical use, some individuals may experience skin sensitization. As with any ingredient, patch testing is recommended for those with sensitive skin or a history of allergic reactions.

Regulatory bodies, including the FDA and EU Cosmetics Regulation, have approved Propyl Gallate for use in cosmetics within specified limits.
