What is Chlorine Dioxide, the Substance Generated by Our Tablets?

Chlorine dioxide is a yellowish-green gas with a strong odor at high concentrations (above 400ppm). At all concentrations, it is a powerful oxidizing agent that was first used as a bleaching agent in the paper industry, then as well as to disinfect water, then to sanitize equipment and then finally discovered to be an excellent product for surfaces, and the removal odors in a variety of residential, commercial and industrial applications. Chlorine dioxide is also used as a sterilizing agent in healthcare facilities and proven to be a better treatment of drinking water as an alternative to chlorine. It is highly reactive and can react with a wide range of substances, making it a versatile and useful chemical for many different applications. However, care must be taken when handling high levels of chlorine dioxide as it can be toxic when consumed in large quantities and can cause skin irritation and respiratory problems. Our directions for use must be followed carefully, and when done so, pose little to no risk. Access our Safety Data Sheet.

Some Chlorine Dioxide Frequently Asked Questions & Answers...

Is Chlorine Dioxide the same as bleach?

NO. While both molecules contain chlorine and oxygen, the differences are astonishing. Bleach contains sodium chloride - in high percentages and quite corrosive; Chlorine Dioxide consumes sodium chlorite to create a new and different molecule. Bleach creates carcinogenic byproducts, ClO2 does not. Bleach will not work as a biocide (disinfectant) outside of a narrow rate of pH, Chlorine Dioxide will. Bleach leaves a residue at almost all usual concentrations, ClO2 does not.

Is Chlorine Dioxide Safe to Handle?

Opening the foil pouch and depositing the tablet into the water (you never want to add water to a tablet) is the time when you want to act with great care. Chlorine Dioxide generating tablets should NEVER be applied to one's skin, ingested or inhaled as a powder. That all being said, when our package directions are properly followed and the precautionary statements fully understood, opening, adding and dissolving tablets to create a liquid solution for cleaning, deodorizing and sanitizing surfaces, air and water can be a simple and safe process, taking only a minute and without encountering any irritation, discomfort or harm.

Is Chlorine Dioxide Safe in Drinking Water?

Remember these three facts about Chlorine Dioxide and you'll be able to answer this question for yourself:

  • Chlorine Dioxide is not hydrolyzed into water, it always remains a gas, and as a gas, and after it has completed its task, will take up residence in the air rather than stay in the water. This alone demonstrates that it is safer than using bleach, peroxide or any metallic or synthetic compound to treat drinking water.
  • Chlorine Dioxide is effective at exceptionally low doses. It requires 70-100 times LESS ClO2 than bleach or peroxide to achieve the same results.
  • Chlorine Dioxide is what is contained within our white blood cells. At these resident low doses, our bodies use ClO2 to fight off infections of bacteria, viruses, fungi and parasites.
But can Chlorine Dioxide Harm You?

At exceptionally high concentrates, yes, Chlorine Dioxide can be harmful:

  • Chlorine Dioxide gas - if you can smell it and the scent is uncomfortable, then definitely wear an appropriate respirator or do not enter the air space. Open the windows and air our the space and you will be left with only a clean, fresh scent.
  • Chlorine Dioxide liquid - It is the gas in the water that is the point, not the liquid water. If you are on a private septic system, do not pour large amounts (gallons) of a strong, prepared solution down your drain. It will destroy the bacteria that is in your tank, breaking down sewage.
  • Chlorine Dioxide generating tablets - Always handle the tablets with care, these will react with even the slightest water from a wet hand and begin the generation process.
Is Chlorine Dioxide a Good Bleaching Agent for Clothes?

While Chlorine Dioxide has been used to bleach wood pulp into paper for nearly a century, it is not really a practical bleach for home use. Unless an article of clothing has been pre-moistened, our tablets have not been known to stain clothing or destroy fabrics like bleach does. Generally speaking, bleach takes color out better than ClO2, but ClO2 destroys microbes MUCH better than bleach.

Does Chlorine Dioxide Kill Bacteria, Mold and Other Microbes?

Definitely, and it has been proven time and time again to be the 'best of the best'. Oxidizers are the best of the disinfectants, and ClO2 is the best of the oxidizers. This is because ClO2 has the lowest corrosive oxidizing strength (it won't destroy surfaces to the degree that bleach, peroxide and ozone will) but it has by far the highest oxidizing potential. This means that it destroys microbes by robbing them of electrons that are essential for metabolism and sustenance. The fact of the matter is that ClO2 has 250% of the oxidizing potential of any of its near competitors: bleach, peroxide and ozone.

How is Chlorine Dioxide Produced and Sold?

Historically, Chlorine Dioxide (which you must keep remembering is a gas at all temperatures over 51oF) has always been generated on location using massive chambers and three very hazardous liquid precursors. This is now restricted to large industrial applications like paper mills. Now, even hospitals and large hotels are treating their waterlines to reduce the likelihood of waterborne microbial contamination. For personal and small commercial applications, it is far preferable to use simpler 2-part liquids or even better yet, tablets, which can be dropped into water of at least 51oF to generate a cleaning, deodorizing and sanitizing solution within a minute or two.

How Do Tablets Create ClO2 Gas in Water Solutions?

All ClO2 is created from sodium chlorite, a salt, which is a solid and can be pulverized to a powder. This powder is then blended with other powders (like citric or hydrochloric acid), buffers and ingredients to bring the solution up to the desired pH level for safer handling. Most tablet manufacturers are cutting corners and producing tablets with a pH as low as 1.6-2.0, which is very corrosive. Our tablets have the same pH as some tap waters, at around 6.0-6.5. We don't cut corners, we just produce great tablets. In the future, we hope to even improve on this impressive statistic.
