Frequently Asked Questions

What is propyl gallate used for?

Propyl gallate (CAS 121-72-2), the n-propyl ester of gallic acid, is a synthetic antioxidant (E310) used to retard oxidation and rancidity in edible fats, oils, and foods. It is also used as an antioxidant in cosmetics, emulsions, waxes, and industrial oils such as transformer oils.

What does NF FCC grade mean for propyl gallate?

NF/FCC indicates the material is tested to National Formulary and Food Chemicals Codex compendial specifications, the grade typically required for food and pharmaceutical-excipient use. The grade and CAS 121-72-2 are confirmed on each lot's CoA.

What is the chemical formula of propyl gallate?

Propyl gallate is the n-propyl ester of 3,4,5-trihydroxybenzoic acid (gallic acid), molecular formula C10H12O5. Refer to the CoA for the lot-specific identity and assay.

How soluble is propyl gallate?

Propyl gallate has limited water solubility and is more soluble in alcohols, oils, and fats, which is why it is dosed into the oil phase of food and cosmetic systems as an antioxidant. See the SDS and TDS for solubility data.

What is the price of bulk propyl gallate NF FCC?

RawSource prices propyl gallate by volume and packaging for food, cosmetic, and industrial buyers rather than a fixed list price. Submit your target quantity and required grade (NF/FCC) for a bulk quote; a CoA and SDS accompany every shipment.
