Propionic acid with not less than 10% and less than 90% acid by mass


Propionic acid (, from the Greek words πρῶτος : prōtos, meaning "first", and πίων : píōn, meaning "fat"; also known as propanoic acid) is a naturally occurring carboxylic acid with chemical formula CH3CH2CO2H. It is an oily liquid with a pungent and unpleasant smell. The anion CH3CH2CO−2 as well as the salts and esters of propionic acid are known as propionates or propanoates. About half of the world production of propionic acid is consumed as a preservative for both animal feed and food for human consumption Wikipedia
