Propyl Gallate[edit]

Propyl gallate is an ester formed from gallic acid and propyl alcohol. It is commonly used as an antioxidant in food, cosmetics, and pharmaceuticals to prevent oxidation and spoilage.

Chemical Properties[edit]

Propyl gallate is a white to creamy-white crystalline powder. It is soluble in ethanol, acetone, and lipids, but has limited solubility in water. The chemical formula for propyl gallate is C₁₀H₁₂O₅.

Uses[edit]

Food Industry[edit]

In the food industry, propyl gallate is used as an additive to prevent rancidity in edible oils and fats. It is often found in products such as vegetable oil, meat products, and snack foods.

Cosmetics[edit]

Propyl gallate is used in cosmetics to stabilize fragrances and prevent the degradation of oils and fats in formulations.

Pharmaceuticals[edit]

In pharmaceuticals, propyl gallate is used to protect active ingredients from oxidation, thereby extending the shelf life of medications.

Health and Safety[edit]

Propyl gallate is generally recognized as safe (GRAS) by the Food and Drug Administration (FDA) when used in accordance with good manufacturing practices. However, some individuals may experience allergic reactions or hypersensitivity to this compound.

Related Compounds[edit]

Propyl gallate is related to other gallate esters such as methyl gallate and ethyl gallate, which also serve as antioxidants.
