A major use of formic acid is as a preservative and antibacterial agent in livestock feed. It is applied on silage (incl. fresh hay) to promote the fermentation of lactic acid and to suppress the formation of butyric acid; it also allows fermentation to occur quickly, and at a lower temperature, reducing the loss of nutritional value. Formic acid inhibits certain decay processes and causes the feed to retain its nutrition longer. In the poultry industry, it is sometimes added to feed to kill E. coli bacteria. Use as preservative for silage and (other) animal feed constituted 30% of the global consumption in 2009. Formic acid is also significantly used in the production of leather incl. tanning (23% of the global consumption in 2009) and in dying and finishing of textile (9% of the global consumption in 2009) because of its acidic nature. Used as a coagulant in production of rubber, constituted 6% of the global consumption. Formic acid is also used for various cleaning products, such as limescale remover and toilet bowl cleaner.
