Overview

Calcium chloride is a calcium salt of hydrochloric acid, and is similar to the more familiar table salt, which has the chemical name of sodium chloride.

Calcium chloride is often used in water-in-oil emulsions to stabilize them, which it does by increasing the viscosity of the product. These types of emulsions are notoriously difficult to stabilize, so the addition of this salt is quite useful.

Calcium chloride can also serve as an astringent. An astringent is a type of ingredient that causes the skin to constrict and dry up, leaving the skin hardened and protected.
