What Is Calcium Chloride?
What It Is
Calcium chloride is an inorganic calcium salt used in cosmetic formulations and also found naturally in saline brines and mineral systems. It can occur as part of the mineral chemistry of complex salts.
What It Does
The source identifies calcium chloride as an astringent and viscosity-controlling cosmetic ingredient. In mineral-salt materials it can also contribute to the overall mineral composition.
How It Functions in a Formulation
Its practical role depends on the grade, hydration state, concentration and finished formula. When present as part of a complex mineral salt, it contributes to the material's overall mineral profile rather than necessarily acting as an isolated active ingredient.
Safety and Tolerance
Raw-material specification matters because calcium chloride can be supplied in different grades and hydration states. The source does not support converting its presence into a specific therapeutic claim for bathing.
What the Source Supports
The source supports calcium chloride as a cosmetic formulation material with documented astringent and viscosity-controlling functions and as a constituent of some mineral systems.
