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