SILVER DIHYDROGEN CITRATE (SDC)
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.
WHY IS SDC UNIQUE?
Stability
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.
Mode of 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.
Safety
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.

WHAT OUR CUSTOMERS SAY
I highly recommend using PURE Hard Surface as your primary disinfectant and sanitizer to use at your school facilities to keep your kids and employees safe. Pure Hard Surface has given us a peace of mind knowing that our facilities are disinfected and sanitized to the highest degree possible.
Matt Fortier
Facilities Director, Franklin RoadAcademy
We have been using PURE Hard Surface in oure facility for over two years, and we are very happy with the results. We also use PURE on our warehouse floors to help control and prevent any forklift traffic cross-contamination into RTE areas.
Deb-Durkee Barnett
Plant Sanitarian, Cabot Creamery
We have seen a significant reduction in yeast and mold in our air since using PURE Hard Surface Sanitizer. This has resulted in improved air quality for the employees. We also appreciate PURE's long-lasting killing power to help us control Salmonella between cleaning cycles.
Jay Merkle
QA Manger, Red Bird Farms
"We use SDC in our sanitation every day. It’s mandatory. Not only that, but we actively try to find new ways to use it…in drains, break rooms, for cleaning harvest materials, and for projects X, Y, and Z. Once we understood the science and efficacy of SDC, we were all in. This product is the final layer of security in our sanitation program. Environmental monitoring and protection are the critical must-have in our operation. It is non-negotiable, and we must be successful. The group at PURE Bioscience have this same mission, so the partnership is obvious."
Marcus Shebl
Vice President of Operations, Taylor Farms California
With more attention being given to environmental monitoring by the FDA, we are glad to have PURE Hard Surface as a tool to help us keep our facility and food products safe.
