CALCIUM POTASSIUM SODIUM PHOSPHATE.

Valuable CAS 131862-42-5 / ABRASIVE, ANTIMICROBIAL, ANTIPLAQUE, ORAL CARE

A multifunctional mineral complex that serves as both a gentle physical refiner and a potent antimicrobial agent. It utilizes ion-exchange technology to support skin health and surface smoothness without the irritation associated with traditional chemical exfoliants.

Summary

Abrasive Antimicrobial Oral Care Agent pH Buffer

Science

Mechanism of Action

Upon contact with moisture, this inorganic salt undergoes an ion-exchange process, releasing calcium, sodium, and phosphate ions. This creates a localized, temporary shift in osmotic pressure and pH levels that disrupts the cell membranes of problematic bacteria like P. acnes, while providing a physical micro-polishing effect to the skin's surface.
