PURE's patented new molecule, Silver Dihydrogen Citrate (SDC), is one of the first new antimicrobials in decades. SDC is an electrolytically generated source of stabilized ionic silver that can serve as the basis for a wide range of products in diverse markets. Colorless, odorless, tasteless and non-caustic, the aqueous SDC formulates well with other compounds. PURE produces and markets pre-formulated, ready-to-use product, as well as varying strengths of SDC concentrate as an additive or raw material for inclusion in other products.
Traditional silver-based disinfectants have short shelf lives – from hours to days. SDC is a stabilized silver ion complex with a shelf life of several years. The unique bond between the silver ion in SDC allows the silver ion to remain in solution while at the same time making it more bio-available for antimicrobial action.
SDC kills microorganisms by two modes of action: 1) the silver ion deactivates structural and metabolic membrane proteins leading to microbial death; 2) the microbes view SDC as a food source, allowing the silver ion to enter the microbe. Once inside the organism, the silver ion denatures the DNA, which halts the microbe’s ability to replicate and leads to its death. This dual action makes SDC highly and quickly effective against a broad spectrum of microbes.
SDC is non-toxic, non-caustic, colorless, odorless, tasteless and does not produce toxic fumes. While SDC is highly toxic to bacteria, fungus and virus it is non-toxic to humans and animals. Based on the EPA toxicity categorization of antimicrobial products that ranges from Category I (high toxicity) down to Category IV, at use dilutions, SDC is rated in the lowest toxicity category, IV, while traditional disinfectants fall into Categories I and II.
