Calcium formate is the calcium salt of formic acid. It is also known as E238. Under this E number it is used as an animal feed preservative within EU, but not in foods intended for people.[5]

Calcium formate is stable at room temperature,[5] is flammable and forms orthorhombic crystals.[2] The mineral form is very rare and called formicaite, and is known from a few boron deposits.
