Potassium Chloride
What is Potassium Chloride?
Potassium chloride is a naturally occurring inorganic compound, a white crystalline salt formed from potassium and chloride ions, often sourced from mineral deposits or produced synthetically through chemical processes. In cosmetics, it belongs to the category of inorganic salts and is commonly found in gels, lotions, shampoos, and cleansers. It functions primarily as a viscosity controlling agent by increasing the ionic strength of the formulation, which influences the behavior of thickening polymers and stabilizers. This helps achieve the desired product consistency, preventing separation, enhancing spreadability, and improving overall sensory experience. Additionally, it can act as a buffering agent to maintain pH balance and support emulsion stability in water-based products.
