AMMONIUM SILVER ZINC ALUMINUM SILICATE.

Valuable CAS 130328-20-0 / ABSORBENT, DEODORANT, PRESERVATIVE

A sophisticated zeolite-based ingredient that functions as a controlled-release antimicrobial system through silver and zinc ion exchange. This mineral complex provides multifunctional benefits including preservation, oil absorption, and bacterial control while maintaining excellent tolerability across skin types. Its unique framework structure allows for sustained antimicrobial activity while simultaneously offering mattifying properties through sebum absorption.

Summary

preservative deodorant absorbent/mattifier

Science

Mechanism of Action

Functions through a zeolite framework that undergoes ion exchange in aqueous environments, gradually releasing antimicrobial silver and zinc ions that disrupt bacterial cell membranes and metabolic processes. The silicate structure simultaneously provides physical absorption of excess sebum and moisture, creating both antimicrobial and mattifying effects on the skin surface.

Dusting Analysis

Not commonly dusted

Regulatory restrictions limit usage to 1.0% maximum concentration, making dusting unlikely as manufacturers must comply with established safety limits

The Formula

Formulation

Solubility
Water
Optimal pH 4 – 9

Stability

Chemically stable within pH 4-9 range with pH-dependent ion release rates, highest silver release at pH 5. Photostable but requires UV protection during storage to prevent silver oxidation.

Conflicts

  • Strong oxidizing agents
  • Chelating agents
  • Anionic surfactants
