    PURE Hard Surface

    First new disinfecting product approved by the EPA in 30 years!
    No other product can make that statement!!

    EPA registered PURE™ Hard Surface disinfectant and food contact surface sanitizer provides an unparalleled combination of high efficacy and low toxicity with 30-second bacterial kill times and 24-hour residual protection. PURE™ Hard Surface completely kills resistant pathogens like MRSA and also effectively eliminates dangerous fungi and viruses including HIV, Norovirus, Influenza A, Avian Influenza and H1N1. PURE™ Hard Surface is registered for use on food contact surfaces and is gentle enough to be used in sensitive children's areas.

    PURE's patented new molecule, silver dihydrogen citrate (SDC), is the first new antimicrobial 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-preformulated, 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 very short shelf lives-from hours to days. SDC is a stabilized silver ion complex with a shelf life of several years. The unique bond of 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.


    SDC is the basis for the EPA registered hard surface disinfectant, PURE™ Hard Surface. Twenty times faster than the leading disinfectants, PURE™ Hard Surface is the next generation of microbial control. Advantages of SDC include:
    • Powerful broad spectrum protection as a disinfectant, fungicide and virucide
    • Kills germs in 30 seconds
    • Provides residual protection for 24 hours
    • Effective against resistant bacteria such as MRSA and VRE
    • Lowest toxicity rating available
    • Labeled for use in diverse environments including restaurants, homes, medical facilities, institutions, day care facilities and on children's toys and play areas



    Pure™ produces and markets varying strengths of SDC concentrate for use as an additive or active ingredient in other products. PURE™ pursues strategic development, licensing and distribution agreements with partner companies for the third party products contain SDC as an additive or active ingredient.


    PURE'S SDC technology also shows promise as a broad-spectrum antimicrobial and anti-fungal for use in human and veterinary health care products. PURE™ has initially chosen to pursue approvals through the U.S. Food and Drug Administration (FDA) by partnering with third-party pharmaceutical development companies. Our partner companies assume responsibility for finding and managing the testing and regulatory process for potential FDA regulated SDC-based products. Current product development projects include dermatology, wound care and medical biofilm control products as well as several products for dental industry. An IND for a hand sanitizer is in process.


    1. Is PURE™ really different than other disinfectants like Lysol?

    A: First of all, the active ingredient in PURE™ is silver dihydrogen citrate (SDC). SDC is patented by the manufacturer. No other manufacturer has it.
    Second, you have to look at what those other products are claiming. Do they call themselves "sanitizers?" If so, by definition they don't kill all the germs.
    Third, look at what those products contain. If they have alcohol or bleach, they aren't "green" and aren't in the lowest toxicity category like PURE™.
    Fourth, look at whether the other products claim to offer 24-hour residual protection, as PURE™ does. They don't! Other antimicrobials only kill germs at the moment they are sprayed onto a surface. The surface quickly gets re-contaminated.
    Fifth, can those other products say that germs cannot develop resistance to them? PURE™ can make that claim.

    2. Is PURE™ a cleaner?

    A: There is a small amount of "surfactant" in PURE™, which gives it a bit of cleaning power. But that is not really what PURE™ is for. PURE™ is first and foremost formulated to protect you and your family from germs. It is a disinfectant.

    3. How is PURE™ different from other silver-based disinfectants?
    A: Most other silver based technologies utilize colloidal silver. PURE™ Hard Surface contains fully active, stabilized ionic silver, silver dihydrogen citrate (SDC), at a specific concentration of 30 parts per million - thousands of times higher than colloidal silver but with exponentially less total silver mass. The patented process developed to manufacture SDC provides stabilized ionic silver in aqueous citric acid solution.

    4. What will PURE™ kill?
    1. PURE™ kills a wide range of bacteria, viruses and fungi including the following: Pandemic 2009 H1N1 Influenza Virus (formerly called swine flu)* Staphylococcus aureus MRSA Pseudomonas aeruginosa CA-MRSA (Community Associated Methicillin resistant Staphylococcus aureus) CA-MRSA-PVL (Community Associated Methicillin resistant Staphylococcus aureus) Acinetobacter baumannii Campylobacter jejuni VRE (Vancomycin-resistant Enterococcus faecium) Salmonella enterica Listeria monocytogenes E. coli (Escherichia coli 0157:H7) HIV type 1 Human Coronavirus Rhinovirus Rotavirus Norovirus Polio Type 2 Influenza A Avian Influenza A Herpes Simplex Type 1 Athlete's foot fungus (Trichophyton mentagrophytes)

    5. How long will PURE™ kill viruses, bacteria and fungi after I apply it?
    A: Common antibacterial surface-cleaning products are alcohol-based and simply kill germs on surfaces at the moment they are applied. PURE™ goes much farther: Once applied to a hard surface, it continues killing germs for at least 24 hours, according to the EPA.

    6. How soon does begin to PURE™ kill viruses, bacteria and fungi after I apply it?
    A: PURE™ kills some viruses, bacteria and fungi in as little as 30 seconds. Consult the product label for more details on kill times.

    7. If I use PURE™ often, will bacteria or viruses build up immunity to it?
    A: No! Bacteria and viruses do not develop a resistance to PURE™.

    8. Is PURE™ patented?
    A: The manufacturer of the product, owns five patents on the technology and has several hundred use patents filed.

    9. Which government agencies have registered PURE™?
    A: PURE™ has been registered by the U.S. EPA.

    10. Can I use PURE™on my skin? Will it irritate my skin?
    A: PURE™ is intended for use on hard surfaces and is not registered for use topically. However, if some gets on your skin, it will not cause skin irritation. Remember to refer to the product label for EPA registered claims.

    11. What if I swallow some PURE™? Is it toxic?
    A: The U.S. Environmental Protection Agency categorizes all antimicrobial products according to a toxicity scale from I to IV (I being most toxic and IV being the least.). Traditional disinfectants, which use active ingredients such as ethanol or ammonium chloride, fall into categories I and II. The SDC dilution used in PURE™ is in category IV, the lowest toxicity level available.

    12. Will repeated use of PURE™ turn my skin blue, like colloidal silver?
    A: No! PURE™ uses ionized silver and will not turn your skin blue. Colloidal silver is simply finely ground silver particles and is not stable, ionized silver is used in the technology in PURE™.

    13. Does PURE™smell bad / smell strong? Can I use it in crowded areas (e.g. an office)?
    A: PURE™ is completely odorless, unlike alcohol or bleach-based products, and can be used in areas where people are around, such as in an office, school or hospital.

    14. Can I use PURE™ in the kitchen near a stove / cook-top? Is it flammable?
    A: PURE™ is not flammable.

    15. If I get PURE™ on my clothes, will it stain or ruin my clothes?
    A: No, PURE™ will not stain fabrics.

    16. Who has tested the product? How do I know it is safe?
    A: The safety of silver compounds has been studied extensively. The EPA has evaluated silver on several occasions and concluded that there are no adverse health effects associated with ingesting silver. The Agency for Toxic Substances and Disease Registry did studies as long ago as 1990 and found silver to have no toxic effects at the doses tested. Tests done by the World Health Organization in 2003 and by the National research Council in 2004 reached the same results.

    17. Who manufactures PURE™ and where is PURE™ manufactured?

    A: Yes, if you have PURE™ in the convenient 3oz package, you are free to travel with it in your carry-on.

    33. What is the difference between a disinfectant and a sanitizer?
    A: There is a general misunderstanding by the consuming public as to the difference between a disinfectant and a sanitizer; the perception being that they are equally effective. In fact, sanitizers only reduce the number of viruses and bacteria (99.9% often advertised) while a disinfectant kills effectively all viruses and bacteria (greater than 99.9999%). Sanitizers are therefore only effective at reducing the number of organisms present on a surface, leaving the remaining organisms to quickly reproduce after the sanitizer's application. Furthermore, the organisms that remain after the application of a sanitizer may become resistant to future sanitizing treatments thereby reducing the effectiveness of a sanitizer after repeated applications. PURE™ is a disinfectant. It not only kills all bacteria on a surface, it also does not allow bacterial resistance.

    34. Why EPA registration?
    A: The U.S. Environmental Protection Agency (EPA) requires all disinfectants to be registered for sale in the United States. In addition, disinfectants must be registered in each state where the product is sold.

    35. Can PURE™ be used to control odors?
    A: PURE™ Hard Surface eliminates odors and disinfects in one-step. PURE works by killing the bacteria that causes the odors, not just covering them up.

    36. What are MRSA and VRE?
    A: Methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-resistant Enterococcus (VRE) are two of the most widespread antibiotic-resistant pathogens that cause hospital/ public facility- acquired infections. ULTIMATE is effective against both VRE and strains of MRSA.

    37. Does PURE™need to be mixed with water?
    A: No, PURE™ comes in a ready to use formula and no mixing is required.

    38. Does PURE™ meet Clean Air and Water Act standards?
    A: PURE™ does not contain any hazardous air pollutants, Class 1 Ozone depletors or Class 2 Ozone depletors. Also, none of the chemicals in PURE™ are listed as Hazardous Substances under the Clean Water Act (CWA), Priority Pollutants under the CWA, or Toxic Pollutants under the CWA.

    39. Can I use any bottle to apply PURE™?
    A: It is important that PURE™ Hard Surface only be stored in opaque bottles (not transparent or translucent) due to the photo sensitivity of silver.

    40. How far will my bottle of PURE™ go?
    A: A 32oz. bottle will disinfect approximately 1,000 square feet.

    41. Is PURE™ fragrance free?
    A: Yes, PURE™ is fragrance free and completely odorless.

    42. Is PURE™ registered in all 50 states?
    A: Yes, PURE™ Hard Surface is registered in all 50 states.

    What can I do to prevent stickiness?
    A: The citric acid in the product causes it to be slightly sticky if it is allowed to dry on the surface without being wiped off. This would be similar to letting an orange juice spill dry on your counter. In order to prevent it from happening, follow the directions for use on the back of the product-spray on the surface, wetting thoroughly; let it sit and then wipe the surface dry.

    44. At what temperatures can PURE™ be stored?
    A: PURE™ should be stored in a cool, dry place and at temperatures above freezing.

    45. Do other products have a 24 hour residual claim like PURE™?
    A: No. PURE™ Hard Surface is the only disinfectant that has an EPA registered claim for 24 hour residual kill claim.

    46. Should I be concerned about a buildup of silver on surfaces I disinfect regularly with PURE™?
    A: No, even at maximum use levels there is no concern of silver buildup on surfaces.

    47. Is PURE™ more environmentally friendly than other disinfecting products?
    A: PURE™ is made from only naturally-occurring elements and it is not harmful to the environment. Most other disinfecting products contain alcohol or bleach, which are both harmful to the environment.

    48. Will the efficacy of PURE™ be reduced when it is used on stainless steel surfaces?
    A: PURE™ Hard Surface is approved for use on stainless steel surfaces and is effective when used on them.

    49. Why is EPA registration so important?
    A: It proves that the U.S. government has tested the product and has verified its efficacy as a germ killer. If a product makes a claim to kill organisms but does not have an EPA registration number on its label, the product is in violation of federal law. Products which are registered by the EPA assure that all claims on the label were tested under EPA approved protocols and reviewed by the EPA.

    50. Do I need to worry about dangerous chemical reactions if PURE™ is combined with other cleaning chemicals?
    A: PURE™ is a ready to use formulation and should not be combined with any other chemicals. If PURE is accidentally exposed to other chemicals, no dangerous fumes or other reactions should occur.

    51. Can I use PURE™ to disinfect my baby's pacifier?
    A: PURE™ for Food Contact Surfaces, which will be available within the next couple months, can be used on pacifiers.

    52. Can I use PURE™ on surfaces that come in contact with my food, like cutting boards?
    A: PURE™ for Food Contact Surfaces will be available later this year and is approved for use on surfaces which come in contact with food without the need for rinsing the surface.

    53. Does PURE™ kill both positive and negative gram bacteria?
    A: Yes. Please refer to the PURE™ label for more information.

    54. PURE™has residual protection against bacteria, but does it also have residual protection against viruses and fungi?
    A:PURE™ has only been approved by the EPA for residual protection against Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonella enterica. These are all bacteria. The EPA has not approved a protocol for testing residual efficacy against either viruses or fungi.

    55. Why does PURE™not have signal words like "caution," "danger" or "warning" on the label?
    A: PURE™ Hard Surface has been assigned the lowest toxicity category allowed by the EPA-Category IV. Category IV products do not require any warning, signal words or first aid instructions on the label. Products that are hazardous are required to carry the label warning: "Hazard to humans and domestic animals."


                                    WHERE AND HOW TO USE

    For disinfecting, spray a hard surface thoroughly with PURE Hard Surface. Don't just mist the surface - wet it completely so the liquid beads up on the surface. The chart on the label tells how long to leave it on the surface. It will be at least 30 seconds, depending on which germs you are targeting. Then, wipe the surface thoroughly with a clean, dry cloth. Microfiber cloths work especially well. Wiping the surface thoroughly will prevent any stickiness.
