Products Description
High-Purity Propionic Acid is a naturally occurring short‐chain fatty acid with the chemical formula C₃H₆O₂. It is a colorless liquid with a pungent odor and is found both in nature and as a synthesized compound.
CAS 79-09-4 Propionic acid is a short-chain saturated fatty acid. It is weakly acidic in aqueous solution, but it is highly corrosive. The steam is irritating to the skin and respiratory tract. At normal temperature and pressure, propionic acid is a clear oil liquid with unpleasant rancidity and pungent smell. It can be miscible with water, ethanol, chloroform and ether.

Propionic Acid For Industrial Use
Food Industry
CAS 79-09-4 Propionic acid is widely used as a preservative in baked goods like bread and cheese. It inhibits mold growth, extending shelf life and reducing food waste. For example, bread manufacturers add small amounts to prevent mold, ensuring freshness during distribution.
Plastic & Polymer Production
It serves as a building block for producing cellulose acetate propionate, used in packaging films, textiles, and consumer electronics. These plastics are valued for their clarity, durability, and resistance to heat.
Pharmaceutical & Personal Care
Although primarily industrial, some derivatives are used in small quantities for cosmetic formulations, acting as preservatives or pH adjusters, contributing to product stability.
