The winter is coming and will again cause problems on roads and airports with its ice and snow. Formates, the salts of formic acid, rapidly remove thin layers of ice and effectively prevent new snow from sticking or a new layer of ice from forming. Also, the waste water is easier to treat than that of other deicing agents because of their good biodegradability and low oxygen demand during the breakdown process. Depending on the concentration of the deicing agent, the freezing point is reduced to as much as minus 50 degrees Celsius. BASF is one of the world’s leading manufacturers of formic acid.
