  • Applications

    2-Ethylhexyl gallate (CAS 34531-26-5) is widely used as an antioxidant stabilizer in polymer formulations, helping retard oxidative and thermal degradation. It is commonly employed in plastics and polyolefins, and is also added to coatings and inks to enhance aging resistance. It also serves as a stabilizer in rubber and adhesive systems to improve durability. In cosmetics and personal care formulations, it may be used as an antioxidant additive to protect ingredients from oxidation during storage and use.
