Propyl Gallate

Product Description

Propyl Gallate is a high-purity synthetic antioxidant widely used in cosmetic and personal care formulations to help protect oils, fats, and sensitive ingredients from oxidative degradation. Manufactured under strict quality control standards, it is valued for its excellent antioxidant efficiency, formulation versatility, and stability-enhancing performance.

As an ester of gallic acid, Propyl Gallate functions as an effective antioxidant, free radical scavenger, and oxidation inhibitor. It helps minimize oxidation-related deterioration, supports ingredient stability, improves color retention, and contributes to extended product shelf life. It is frequently incorporated into multi-antioxidant systems to strengthen overall oxidative protection.

Its strong compatibility with oil-based systems and synergistic performance with Tocopherol make it a preferred antioxidant stabilizer for modern cosmetic formulations requiring enhanced shelf life, formula stability, and long-term oxidative protection.
