Calcium Formate
An inorganic salt of formic acid used across animal feed, construction, leather tanning, agriculture and de-icing applications.
Overview
A biodegradable, low-toxicity multi-purpose salt.
Calcium formate is used across animal feed, construction, tile and grout repair, waterproofing compounds, leather tanning and agriculture. It is used as a feed preservative that helps prevent microbial growth and extend feed shelf life.
In leather processing, it improves chrome penetration and can substitute for formic acid. In construction, it is a useful additive for cement and grouts, enhancing concrete properties and reducing setting time. Calcium formate is environmentally friendly, biodegradable and safe to handle — and serves as an effective deicer that is less corrosive than calcium chloride salts.

Application Areas
Where Calcium Formate is used.
Toxicity
Low order of toxicity.
In rats, the acute oral LD50 is 2650 mg/kg; by intravenous injection, the LD50 is 154 mg/kg. Calcium formate is expected to be irritating to the eyes and skin — in case of eye contact, immediately flush with water for 15 minutes and avoid prolonged or repeated skin exposure.
Shipping, Handling & Storage
Packaged for palletized freight.
Available in 25 kg BOPP laminated bags, palletized, with 1,000 kg (2,205 lb) super sacks also available. Calcium formate is not hygroscopic, so when stored in a dry, covered area it can be held for a minimum of 3 years before use in a production line. It is classified as "DOT not regulated" by the US Department of Transportation — no special labeling is required for shipment.
