Sodium Silver Aluminum Silicate
What is Sodium Silver Aluminum Silicate?
Sodium Silver Aluminum Silicate is a synthetic zeolite, a microporous aluminosilicate mineral framework infused with silver ions and sodium. Produced through ion exchange, it mimics natural zeolites but is engineered for cosmetic stability. Commonly used in deodorant sticks, powders, and oil-absorbing skincare products like mattifying primers. In formulations, its porous structure traps water and sebum, promoting a dry, lightweight feel and preventing clumping in powders. The silver ions activate slowly with moisture, disrupting bacterial cell walls to curb odor without impacting sweat glands. This dual absorbent-antimicrobial mechanism supports long-lasting freshness in underarm and body products, blending seamlessly into anhydrous or emulsion systems for shine control.
