SILVÉRION® 2400 is a water-soluble antimicrobial preservative containing Silver Dihydrogen Citrate, a revolutionary, novel ionic silver technology for use in personal care formulations.
This broad-spectrum preservative is an easy-to-use, clear and low viscosity solution with excellent water solubility which is effective at low concentrations and compatible with many other preservatives. It demonstrates good compatibility with other cosmetic ingredients.
This effective alternative to formaldehyde donors and parabens can be used in diverse product forms, including clear gels. It functions as a stand-alone preservative, or it may be combined with other preservatives.
SILVÉRION® 2400 is cost-effective, natural*, easy to dose and formulate with a high bioavailability in the water phase.
0.1 – 1%
Citric Acid (and) Silver Citrate
SILVÉRION® 2400 is a low viscosity liquid which can be easily dosed. The highly water-soluble antimicrobial can be incorporated into the aqueous phase of gels, surfactants and emulsions produced in a cold process.
In the manufacturing of emulsions produced by hot processes, the antimicrobial active must be added to the final formulation after the emulsion has cooled down. Exposure of the antimicrobial active to pH higher than 7 should be avoided in order to achieve optimal formulation stability.
*SILVÉRION® 2400 is not COSMOS-registered, but is COSMOS-conform.
Traditional silver-based disinfectants have short shelf lives – from hours to days. SDC (Sodium Dihydrogen Citrate) 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, colourless, odourless 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.
