What does this ingredient do in an antiperspirant?
CosIng lists Calcium Chloride with the functions astringent and viscosity controlling.
Part of a system, not a label in isolation
In formulas, the salt helps achieve the right thickness and stability of the base. Calcium chloride is not an antiperspirant active and does not replace one.
Calcium Chloride is not listed in the restrictive annexes of EU Regulation 1223/2009; the safety assessment applies to the finished formula.
Tolerance depends on the whole formula; on irritated skin, salts in the formula may be felt more strongly.
Calcium Chloride is not the same as Aluminum Chloride: aluminum chloride is an antiperspirant active, while calcium chloride works as a viscosity controller in cosmetics. The CosIng function astringent refers to a tightening effect on the skin, not to reduced sweating.
