Frequently Asked Questions
Answers to the questions about our products and policies.
What is Chlorine Dioxide?
Chlorine Dioxide is a small, volatile molecule, that reacts with other substances by means of oxidation. It exists as a greenish gas at normal temperatures. Because it is a gas, chlorine dioxide cannot be safely transported in large quantities. Chlorine dioxide is usually generated on-site as needed by mixing precursor chemicals.
Chlorine dioxide is used everyday in food service, municipal water, mold treatment, odor treatment, medical use, mouthwashes, toothpastes, eye-care, and personal water treatment products, among other applications. It is also considered to be a more earth friendly alternative to many chlorine applications..
If it only exists as a gas how can I use it?
There are a couple ways. Because it is a gas, chlorine dioxide cannot be safely transported in large quantities. Chlorine dioxide is usually generated on-site as needed by mixing precursor chemicals. Industrial applications may use very strong acids, and chlorine to generate large quantities of gas.
Chlorine Dioxide vs Chlorine: What's the difference?
Chlorine Dioxide has a lower oxidation strength than chlorine, but more than twice the oxidative capacity. Reduction/Oxidation Strength or "Redox" is a measure of how strongly an oxidizer reacts with with organic material, the higher the redox potential, the more substances the oxidizer will react with. Chlorine Dioxide has a lower redox potential than ozone, chlorine, or hypochlorus acid. Because of this lower redox potential, Chlorine DIoxide is more selective in what it reacts to.
Typically Chlorine DIoxide will only react with compounds that have active carbon bonds, sulfides, cyanides, and compounds with reduced iron or manganese. Chlorine has a higher redox, and will react with a wider range of compounds, including ammonia. Because of this difference Chlorine DIoxide does not create toxic by products like chlorine does. This is why Chlorine is limited as a biocide in it's overall effectiveness as opposed to Chlorine DIoxide.
The higher oxidation capacity means that Chlorine Dioxide will remove 5 electrons from the target, whereas chlorine replaces 2. Chlorine will bind to a pathogen, and other chemicals and compunds that may be present. Chlorine DIoxide being more selective, will not bind with other compounds. Because of this capacity, Chlorine Dioxide is more efficient than Chlorine, Ozone, or Hypochlorus Acid when used as a disinfectant.
After the reaction is complete, Chlorine Dioxide reverts to chloride (salt). Chlorine forms Tri-halomathanes from reaction to ammonia, plus other byproducts from other chemicals and compounds as may be present.
If chlorine dioxide is a germ-killer, why don't you advertise it as such?
In order to make claims that your product kills germs, you must be registered with the EPA as a pesticide.
Our products are offered for surface cleaning, deodorizing,and similar household uses, as well as oxidative applications.
We do not have EPA registration, so we cannot offer any product with claims to sanitize or disinfect.
The FDA does not recognize sodium chlorite or chlorine dioxide as a nutritional supplement, or a medicine.
We absolutely cannot discuss any medical condition, or instructions for human ingestion. Please do not ask.
What is the difference between 28% Sodium Chlorite and 22.4% sodium chlorite?
When people say 28%* Sodium Chlorite, they actually mean 22.4% Sodium Chlorite.
Anhydrous Sodium Chlorite Flakes or Powder is the raw material used to make the solution.. It is shipped and sold as Technical Grade Sodium Chlorite at 80% purity.The remaining 20% are buffers such as, Sodium Chloride (common salt), Sodium Carbonate, Sodium Hydroxide, Sodium Sulfate and leftover Sodium Chlorate from the manufacturing process.
You cannot acquire pure sodium chlorite. It is too unstable, and extremely dangerous to handle. I have seen 90% Sodium Chlorite from China, but it is industrial grade, and no regulation as to heavy metals or chlorate content.
When you combine the water and the 80% sodium chlorite flakes at a w/w (weight to weight) ratio of 28% Sodium Chlorite and 72% distilled water, the resulting solution will contain 22.4% actual sodium chlorite, 5.6% buffer ingredients, and 72% water. The total of the actual dissolved solids are 22.4% NaClO2 + 5.6% Inert Buffers which equals 28% total dissolved solids in the solution.
In other words, what is commonly mislabeled as 28% sodium chlorite is actually 22.4% sodium chlorite.
I thought it turned dark faster than it does. What's up?
Most often it has to do with what type of sodium chlorite is being used.
We use only EPA registered sodium chlorite. It is more highly regulated than sodium chlorite intended for industrial use.
Industrial Sodium chlorite is the easiest to find. It also costs quite a bit less than EPA registered chlorite. A lot of it is manufactured in China, and distributed through chemical supply companies. The main uses for this are pulp bleaching, oil field use, and other applications in which the killing of pathogens is not the primary goal. Industrial grade Sodium Chlorite is usually quite high in Sodium Chlorate (NaClO3) and Sodium Hydroxide (NaOH), and buffered with common salt. Industrial Grade sodium chlorite can also contain a high amount of lead, mercury, and arsenic. When used to make a solution, industrial grade chlorite will be cloudy for awhile, often requiring to sit for a day or two before it clears. Brown sediment is visible on the bottom, and a foam may remain on top until you skim it off. Solutions made with industrial grade sodium chlorite may seem to activate "better", turning a dark amber quickly. This is due to the Sodium Chlorate producing both Chlorine Dioxide, as well as Chlorine, and other chlorine compounds. Turning dark faster does not necessarily mean more Chlorine Dioxide.
Other factors can include the amount being mixed, the vessel it is mixed in, ozonated water, UV, and ambient light.
1 oz will appear darker than 3 drops, even when mixed at the same ratio.
How is your CDS made? Why is it different than CDH or CD Kits
Our CDS is a very pure chlorine dioxide gas absorbed into water. Our entire system is made of laboratory glassware with glass fittings, and PTFE tubing. We use a proprietary method and stoichiometric ratio, It is a forced air system with 3 scrubbers to remove free chlorine and HCl gases that are present in the initial release of gas from the reaction of Sodium Chlorite with HCl . The reagent chamber uses only heat distilled water with no ozone, chilled to ≤ 42F.
Our method and ratio produce an aqueous chlorine dioxide solution between 5000 and 6000 ppm. We test using the DPD method Colorimetry test, and dilute to strength. Our system produces 99+% pure CLO2. It degrades at a slower rate than products made by direct infusion or activation, due to impurities being removed in the production process.
Whats the difference between a CD Kit, CDH, and CDS
CD Kits are the basis for the other 2 products. They contain Sodium Chlorite (Part A) and an activator acid (Part B). When they are combined Chlorine Dioxide is formed' The drops create a small amount of concentrated free chlorine dioxide, and some chlorine dioxide is left in reserve as chlorous acid. The combined drops can then be mixed with water to the desired strength. The number of drops and amount of water you use depend on your application. 3 combined drops activated for 1 minute will result in approx 25 to 30 ppm free chlorine dioxide when 4 oz of water is added. The pH of the combined drops is approx 3.5, and ppm of chlorine dioxide is about 15,000 ppm available Chlorine Dioxide
CDH is acidified sodium chlorite. It is simply a premix of the combined drops at a much weaker concentration. It isn't as economical, and the shelf life is greatly reduced. It takes 20 times as much CDH to produce the same result as the CD Kits. The only advantage is convenience.
CDS is aqueous chlorine dioxide. It is pure chlorine dioxide absorbed into distilled water. There is no chlorine dioxide in reserve and.It doesn't contain acid. It is bottled at 3000 ppm to allow limited quantity ground shipments. The process for making it correctly requires more equipment, time and steps than the others.
Why can't you send it to a PO Box?
Chlorite solutions, and HCl are considerid hazardous by the U.S.DOT They can only be sent ground, as a consumer commodity packaged for the end user. This is what the affixed sticker signifies.
|Limited Quantity Exception - Ground Service (49 CFR HM-215K) |
If the "Ground and Air Packaging Provisions Exceptions" column of the chemical table references a specific packaging exception, refer to that section of 49 CFR to determine if your material qualifies for the exception. If you do not meet all the conditions for that exception, you must prepare the material under the rules for a fully regulated hazardous material.
Chorite Solution, UN1908, Class 8 PGII,
Why is my DMSO is solid instead of gel or liquid.
No need to be alarmed. Remember, not every chemical or element melts and freezes at the same rate and temperature. DMSO has a melting point of 66.2° F (19° C). this means it crystallizes or "Freezes" at 66.2 F
In the winter time , you may receive your DMSO and find it to be a solid mass. This is normal in the case of DMSO. We are in Florida, and occasionally our DMSO is received below melting temperatures. DMSO cools rapidly, and thaws slowly. Just place it in a warm spot and let it thaw out.
Our DMSO is 99.95% Pure, so you can use it as it thaws.
