Silver Citrate
What is Silver Citrate?
Silver Citrate is a silver salt derived from citric acid, a tricarboxylic acid present in fruits like lemons. Chemically, it consists of silver ions bound to citrate molecules, forming a stable, water-soluble powder. In cosmetics, it functions as an antimicrobial preservative and deodorant agent, commonly found in deodorants, oral care products, and skin formulations needing microbial control. It operates by liberating silver ions that bind to bacterial and fungal enzymes, disrupting their cell respiration and replication processes. This ionic mechanism provides broad-spectrum activity without promoting resistance like some organic preservatives. Stable across typical cosmetic pH ranges, it integrates seamlessly into water-based formulas, aiding product stability while contributing to surface-level skin protection.
