What Is Calcium chloride?

Calcium chloride is a naturally occurring salt derived from limestone. It is a white solid and can also be produced synthetically.[1] It is solid at room temperature and dissolves in water.[2,3]

What Does Calcium chloride Do in Our products?

Calcium chloride is often used as a nutrient supplement, stabilizer, thickener, and texturizer in food; it is frequently found in baked goods, dairy products, beverages, juices, coffee, tea, condiments, jellies, meat products, and other products.[4] It can help replenish calcium and can be an antidote for magnesium poisoning.[5] Calcium chloride is also a pH adjuster/water softener, which is why it is commonly used as a brine in refrigeration plants, as well as a tool for ice and dust control on roads. It absorbs moisture from the air, and when it’s added to liquids it absorbs water. For this reason, it is a drying agent. Calcium chloride is present in dozens of personal care products, including bath oils, deodorant, sunscreen, conditioner, and makeup.[6,7]

Why Puracy Uses Calcium chloride

We use calcium chloride in several of our products as a pH adjuster/water softener. The FDA has deemed the ingredient generally recognized as safe (GRAS).[12,13] Whole Foods has deemed the ingredient acceptable in its body care and cleaning product quality standards.[14,15] Research shows that the ingredient is not a skin irritant in low concentrations.[16,17,18]

How Calcium chloride Is Made

Calcium chloride occurs naturally in limestone; its production is primarily a reaction of limestone with hydrochloric acid.[8] It is often commercially produced as a byproduct in the ammonia-soda process (called the Solvay process).[9] It can also be made by substitution reactions with other calcium and chloride salts, and in the United States it can be made by concentrating and purifying brines from salt lakes and salt deposits.[10,11]
