Potassium Sulfate

Potassium Sulfate is an inorganic salt that occurs naturally in mineral deposits or is synthetically produced. In cosmetic formulations, it primarily serves as an ionic strength modifier and viscosity regulator, particularly useful in surfactant systems where it can influence micelle formation and product texture without significantly altering pH. Formulators choose it for its high purity, excellent solubility in water, and ability to enhance the stability of certain emulsion systems while maintaining a clean, minimal ingredient profile.
