Use

Formic acid has a number of commercial uses. It is used in the leather industry to degreaseand remove hair from hides and as an ingredient in tanning formulations. It is used as alatex coagulant in natural rubber production. Formic acid and its formulations are used aspreservatives of silage. It is especially valued in Europe where laws require the use of naturalantibacterial agents rather than synthetic antibiotics. Silage is fermented grass and crops thatare stored in silos and used for winter feed. Silage is produced during anaerobic fermentationwhen bacteria produce acids that lower the pH, preventing further bacterial action. Acetic acidand lactic acid are the desired acids during silage fermentation. Formic acid is used in silageprocessing to reduce undesirable bacteria and mold growth. Formic acid reduces Clostridiabacteria that would produce butyric acid causing spoilage. In addition to preventing silagespoilage, formic acid helps preserve protein content, improves compaction, and preservessugar content. Formic acid is used as a miticide by beekeepers.
