SCCS Publishes Final Opinion on Silver Zinc Zeolite

The Scientific Committee on Consumer Safety (SCCS) concludes that Silver Zinc Zeolite (CAS No. 130328-20-0) with a maximum silver content of 2.5% is safe in spray deodorant and powder foundation when used at a concentration of 1%. The SCCS also considers the maximum concentration of silver zinc zeolite as a preservative in cosmetic products to be safe.

The content provides information on the chemical and physical specifications of silver zinc zeolite, including its chemical identity, trade names, structural formula, physical form, purity, impurities, solubility, partition coefficient, and additional physical and chemical specifications.

The liver and skin are the main storage centers for silver in the body, while zinc is found in all tissues. Dermal absorption of silver and zinc from Silver Zinc Zeolite (SZZ) in cosmetic products is likely to be low. The dermal absorption of silver is less than 1%, and for zinc, it is less than 2%.
