Product Benefits

Propionic acid, also known as methylacetic acid, is miscible with water, ethanol, and other solvents. Propionic acid has dual application value in both feed and pharmaceuticals. In the feed sector, propionic acid and its salts are important feed mold inhibitors and preservatives, exhibiting effective inhibitory effects on molds and aerobic bacteria. They can effectively prevent feed heating, caking, nutrient loss, and mycotoxin production, significantly extending feed shelf life. In the pharmaceutical sector, propionic acid is an important pharmaceutical intermediate, and its derivatives can be used in the production of drugs such as vitamin B6, naproxen, and naftidrofuryl. Propionic acid itself has a weak inhibitory effect on fungal growth both in vivo and in vitro, and can be used for the treatment of dermatophytosis.

Feed mold prevention

Exhibits effective inhibitory effects on molds and aerobic bacteria, prevents feed heating, caking, and nutrient loss, preserves the original nutritional value of feed, and avoids mycotoxin contamination.

Silage preservation

As a silage additive, it inhibits the growth of yeasts and molds, prevents aerobic spoilage of silage and secondary fermentation after opening the silo, and reduces nutrient loss.

Pharmaceutical synthesis

It is an important pharmaceutical intermediate, and its derivatives can be used in the production of drugs such as vitamin B6, naproxen, and naftidrofuryl, possessing broad application value in the pharmaceutical industry.

Antimicrobial application

It has a weak inhibitory effect on fungal growth both in vivo and in vitro, and can be used for the treatment of dermatophytosis, often formulated with zinc undecylenate and other agents into compound preparations for external use.
