? Did You Know?
Calcium Chloride occurs naturally in Sea water and brine and Limestone caves (as solution). Many people consume it daily without realizing it's also a listed food additive.
Beyond food, Calcium Chloride is also used in cosmetics, medicine, industrial applications, household products. Its versatility makes it one of the most multi-purpose chemical compounds in everyday life.
In the EU, Calcium Chloride has a "quantum satis" authorization — Latin for "as much as needed." This means there's no specific maximum limit; manufacturers use only what's technologically necessary.
