Propyl Gallate is a highly effective synthetic phenolic antioxidant widely used to prevent rancidity and oxidative degradation in fats, oils, and fat-containing foods, cosmetics, and pharmaceuticals. It exhibits superior oil solubility and heat stability compared to natural antioxidants while offering excellent synergistic effects with BHA, BHT, TBHQ, tocopherols, and ascorbic acid derivatives.
It is globally approved for food, feed, cosmetic, and pharmaceutical applications.

Frequently Asked Questions (FAQs)

Is Propyl Gallate natural or synthetic?
It is synthetic but produced from naturally occurring gallic acid (derived from plant tannins). It is considered a nature-identical antioxidant.

Does Propyl Gallate work in water-based products?
Its activity is limited in aqueous systems due to low water solubility. For water-based foods, gallates are often combined with ascorbic acid or used in emulsified systems.

What is the difference between Propyl Gallate, Octyl Gallate, and Dodecyl Gallate?
All three are esters of gallic acid. Propyl Gallate offers the best heat stability and oil solubility, making it the most widely used in frying and high-temperature applications.

Is it allowed in baby food?
No. It is not permitted in foods for infants and young children in the EU and many other countries.
