Silver chloride

Silver chloride (CAS 7783-90-6, EC 232-033-3, formula AgCl) is an inorganic silver salt also referred to as silver(I) chloride or silver monochloride. It carries no assigned E-code. It is registered under REACH and handled as a regulated substance due to its silver content and aquatic toxicity profile.

In antimicrobial formulations, silver chloride releases silver ions that disrupt bacterial cell membranes and inhibit enzyme activity, making it effective as a preservation agent in wound-care products and cosmetic systems. In electrochemical and photocatalytic applications, it serves as a reference electrode material and a light-sensitive catalyst in analytical and sensing devices.

Silver chloride is supplied as a white crystalline powder and available in reagent, technical, and pharmaceutical-grade specifications, with Ph.Eur. compliance relevant for healthcare applications. Procurement quantities range from laboratory-scale packaging to bulk consignments. Buyers should confirm REACH registration status and applicable SDS documentation prior to import within the EU.
