People consume naturally-occurring propionic acid in common foods such as butter and cheese Used as a preservative, fungicide, and antimicrobial agent Flavoring agents. It is added directly to drinking water for livestock and poultry.Propionic acid was first registered as a pesticide in the early 1970's. It is not subject to the usual pesticide toxicology data requirements.

 

Manufactured by chemical synthesis or by bacterial fermentation Chemicals used for processing: Ethanol, ethylene and carbon monoxide, propionaldehyde, nickel propionate, bromide

 

Very pure propionic acid can be obtained from propionitrile.

 

Do not ingest. Very hazardous in case of inhalation. Can irritate the lungs. Repeated exposure may cause bronchitis to develop with coughing, phlegm, and/or shortness of breath.

 

Hazardous in case of skin contact (irritant), of ingestion.

 

The substance may be toxic to lungs, gastrointestinal tract, upper respiratory tract, central nervous system

　

CORROSIVE

COMBUSTIBLE

POISONOUS GASES ARE PRODUCED IN FIRE

 

Propionic Acid can cause headache, nausea, vomiting, diarrhea and abdominal pain.

 

If Propionic Acid is spilled or leaked, take the following steps: Evacuate personnel and secure and control entrance to the area.

 

Propionic Acid reacts violently and explosively with OXIDIZING AGENTS (such as) PERCHLORATES, PEROXIDES,PERMANGANATES, CHLORATES, NITRATES, CHLORINE, BROMINE and FLUORINE and PHOSPHORUS TRICHLORIDE.

　

Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk,

 

Personal Protection:

Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves.

 

The products of degradation are as toxic as the product itself.
