Calcium formate, Ca(HCOO)₂, is the calcium salt of formic acid, HCOOH. It is also known as food additive E238 in food industry. The mineral form is very rare and called formicaite. It is known from a few boron deposits. It may be produced synthetically by reacting calcium oxide or calcium hydroxide with formic acid.
