What Is Potassium Chloride?
What It Is
Potassium chloride is an inorganic salt composed of potassium and chloride ions. It occurs in mineral deposits and saline brines and is also manufactured for commercial applications.
What It Does
The source identifies potassium chloride primarily as a viscosity-controlling cosmetic ingredient and notes its presence as part of the mineral composition of highly mineralised brines.
How It Functions in a Formulation
In a mineral-salt formulation, potassium chloride can contribute to the overall dissolved mineral profile. In suitable cosmetic systems it can also contribute to viscosity control. Its actual function depends on concentration and formulation design.
Safety and Tolerance
The source does not establish a systemic potassium-supplementation effect from bathing. Product concentration, formulation design and individual skin tolerance remain the relevant practical considerations.
What the Source Supports
The source supports potassium chloride as a mineral and cosmetic formulation material. Its presence in a bath product should not be interpreted as evidence of meaningful potassium delivery to the body through the skin.
