Aplicaciones

Formic acid is principally used as a preservative antibacterial agent in livestock feed, in dying textiles, tanning leather and electroplating. In the poultry industry, it is sometimes added with feed to kill E. coli bacteria. It acts as a reducing agent for the catalytic reduction of nitrate in water.

Notas

Hygroscopic. Store closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.
