Sourcing Propionic Acid? ChemicalDekho facilitates supply from global majors like BASF and Dow (via importers). Secure bulk supplies for manufacturing preservatives and herbicides.
Propionic Acid (CAS 79-09-4) is the premier anti-mold agent. Its salts (Calcium/Sodium Propionate) are universally used to preserve bread and baked goods (E280 class). In agriculture, it is sprayed on grain silos and animal feed to prevent mold growth during storage. It is also a key intermediate for manufacturing herbicides (Propanil) and ibuprofen.
Listings usually feature 99.5% pure material in drums or tankers. It has a distinct pungent, rancid odor.

Causes severe skin burns and eye damage. Flammable liquid. Pungent odor may irritate respiratory tract.
It has a sharp, pungent, rancid smell, somewhat between vinegar and body odor. (It is actually produced by bacteria in sweat!)
Bread is prone to mold. Propionates inhibit mold growth without affecting the yeast's ability to rise the bread. It extends shelf life from days to weeks.
The acid itself is corrosive. However, its salts (Calcium Propionate) used in food are GRAS (Generally Recognized As Safe) and completely non-toxic to humans.
Propionic acid itself is not, but it is the raw material to make herbicides like Dichlorprop and Propanil.
