FAQs – Propyl Gallate Sourcing :


Q1: What is Propyl Gallate (CAS 121-79-9)?


A: Propyl Gallate (CAS 121-79-9), Sinanox® PG, is an ester formed by the condensation of gallic acid and propanol. It is a white to creamy-white crystalline powder that functions as a highly efficient, fat-soluble antioxidant. It protects lipids, essential oils, and organic matrices from free-radical degradation and oxygen-induced rancidity.


Q2: What are the common uses of Propyl Gallate?


A: The common uses of Propyl Gallate focus heavily on its superior antioxidant properties. In the food and feed sectors, its main uses are preventing oxidation in vegetable oils, animal fats, and pet food. In cosmetics and industrial manufacturing, it serves as a critical stabilization additive to ensure the chemical longevity of luxury personal care items, lubricating oils, and biodiesel formulas.


Q3: How does Propyl Gallate differ from Propylene Glycol or Propyl Hydroxybenzoate?


A: Buyers should not confuse Propyl Gallate with other propyl-derivative chemicals:Propylene Glycol is a liquid humectant and solvent, completely different in chemical structure and function.Propyl Hydroxybenzoate (Propylparaben) is primarily an antimicrobial preservative against mold and bacteria, rather than an antioxidant.Propyl Gallate (Sinanox® PG) is strictly an oxygen-scavenging antioxidant. As a leading B2B chemical supplier, we provide separate, clear technical lines and direct pricing for bulk orders of all these specialized raw materials.


Q4: Where can I buy high-quality Propyl Gallate in large quantities with the best prices?


A:  Our proprietary brand Sinanox® PG stands for direct-factory pricing, guaranteed purity, and consistent multi-ton export capacities. you can contact our global export desk today to request real-time price quotes, custom packaging options, and arrange for pre-shipment sample testing.
