Propionic Acid

Description

What is Propionic Acid?

Propionic Acid (C₂H₅COOH) is a colorless, oily liquid with a pungent, slightly sweet odor. It is a naturally occurring carboxylic acid found in small amounts in dairy products and produced industrially by the hydrocarboxylation of ethylene. Known for its antimicrobial and preservative properties, Propionic Acid is widely used in food, agriculture, and industrial applications.

Its ability to inhibit the growth of molds and bacteria makes it an effective food preservative, while its role as a chemical intermediate supports various industries such as plastics, pharmaceuticals, herbicides, and flavors & fragrances.
