What Is Calcium Chloride?

Calcium chloride is a naturally occurring salt that's often derived from limestone (though it may also be produced synthetically).[1] It is solid at room temperature and dissolves in water.[2]

How Calcium Chloride Is Made

Calcium chloride occurs naturally in limestone and is primarily a reaction of limestone with hydrochloric acid, calcium, or chloride salts. [4] It is often commercially produced as a byproduct in the soda ash process (called the Solvay process).[1] In United States, many manufacturers concentrate brines from salt lakes and salt deposits.[4]

What Does Calcium Chloride Do?

Calcium chloride is present in dozens of personal care products, including bath oils, detergents, sunscreen, conditioner, and makeup.[2,3]

It may be used as a brine for refrigeration plants, a method to control ice on roads, and as a desiccant (thanks to its ability to absorb moisture).[4]

Why Puracy Uses Calcium Chloride

Puracy uses calcium chloride to increase and improve a formula's viscosity to stabilize the plant-based enzymes in our laundry products.

Is Calcium Chloride Safe?

Whole Foods has deemed the ingredient acceptable in its body care quality standards.[5] and EWG provides a "1" for the ingredient. [3] Research shows that the ingredient is not a skin irritant when used in low concentrations.[6]
