A functional mineral salt. Safe.
Potassium Chloride is a mineral potassium salt. INCI: Potassium Chloride. In a formula it serves technical roles: it adjusts the viscosity of water-based formulas, takes part in buffer systems, and provides electrolytes in physiological solutions and toning products. It is a functional component, not a skincare active. It has no action on skin of its own and helps the formula hold the right consistency and stability. Pregnancy safety. A mineral salt at cosmetic concentrations is systemically negligible, with no evidence of harm in topical use. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low, suitable for sensitive skin.
