About

A composite antimicrobial preservative system permitted in EU Annex V at up to 0.004% (as AgCl), used to provide antimicrobial protection in cosmetic formulations.

Silver chloride deposited on titanium dioxide is an antimicrobial preservative system used in cosmetic products. It is listed in EU Annex V (preservatives) with a specific limit of 0.004% calculated as silver chloride. The silver ion release mechanism provides antimicrobial activity while the titanium dioxide carrier reduces the free silver ion concentration. Hazard statements include H290 (may be corrosive to metals), H335 (respiratory irritation), and H400/H410 (aquatic toxicity), though at the permitted concentrations these risks are managed.
