Removes Metal Ions

Anti-Aging Benefits

Antioxidant Protection

Locks In Moisture

Prevents product degradation, Maintains optimal pH, Binds metal ions

Traditional Use

Developed in the late 19th/early 20th century as an industrial chemical, later adopted in cosmetics for its pH-buffering and conditioning properties, building on the historical use of silicate minerals in skincare.
