Propyl gallate, or propyl 3,4,5-trihydroxybenzoate is an ester formed by the condensation of gallic acid and propanol. It is an antioxidant added to foods containing oils and fats to prevent oxidation. Propyl gallate is an anti-oxidant. It protects against oxidation by hydrogen peroxide and oxygen free radicals, in a catalytic manner similar to superoxide dismutase.
Propyl gallate is used to protect oils and fats in products from oxidation.
It is used in foods, cosmetics, hair products, adhesives, and lubricants.
It is used as a triplet quencher in fluorescence microscopy.

Antioxidant for Food and Pharmaceuticals

Its consistent quality and availability in various forms make it suitable for large-scale industrial applications and research uses. Each shipment adheres to international regulations, including the HS code 29189900.

FAQs of Propyl gallate:

Q: How is Propyl gallate typically used in industry?

A: Propyl gallate is primarily used as an antioxidant to prevent oxidation in edible oils, processed foods, cosmetics, and pharmaceuticals. It extends shelf life and maintains product quality by inhibiting the deterioration caused by exposure to air.

Q: What are the key benefits of adding Propyl gallate to products?

A: The main benefit of Propyl gallate is its ability to preserve product stability by preventing rancidity and degradation due to oxidation. This protection helps retain flavor, aroma, and nutritional value in food while also maintaining the efficacy of cosmetics and pharmaceuticals.

Q: When should Propyl gallate be added during the manufacturing process?

A: Propyl gallate is best incorporated during the production phase, often blended with fats, oils, or carrier solvents. Adding it early ensures comprehensive antioxidant protection throughout the finished products shelf life.

Q: Where should Propyl gallate be stored to maintain its stability?

A: Propyl gallate should be stored in a sealed containeroften an HDPE or fiber drum with an inner polyethylene bagprotected from moisture, excessive heat, and direct sunlight. A cool, dry storage area helps ensure its stability for up to two years.

Q: What is the recommended method for packaging Propyl gallate for export or bulk use?

A: For export or bulk supply, Propyl gallate is usually packaged in 25 kg HDPE drums, fiber drums, or bags, always sealed with an inner polyethylene bag to prevent moisture ingress and preserve purity during transit and storage.

Q: How soluble is Propyl gallate in water and common solvents?

A: Propyl gallate is only slightly soluble in water but dissolves readily in ethanol, ether, and acetone, making these solvents preferable for solutions and formulations requiring homogenous distribution.
