Description
Silver citrate (CAS 126-45-4) is an inorganic silver salt of citric acid, commercially known under the trade names Itrol and Silberol. It carries no assigned E-code and is registered under EC number 204-786-8. The compound is also referred to as trisilver citrate or trisilvercitrate in technical literature.
In water treatment and healthcare applications, silver citrate functions as an antimicrobial agent by releasing silver ions that disrupt bacterial cell membranes and inhibit enzymatic activity. In personal care formulations, it serves as a preservation booster, extending product shelf life by suppressing microbial growth at low concentrations. The citrate ligand also provides mild chelating action, sequestering metal ions that could otherwise destabilise a formulation.
Silver citrate is supplied as a pharmaceutical-grade powder and is subject to REACH registration requirements for European trade. Buyers should confirm compliance with relevant pharmacopoeial standards when sourcing for medicinal or cosmetic applications. Standard packaging formats include sealed drums and multi-layer bags suited for moisture-sensitive materials.
