CDL 0.3% Chlorine Dioxide Solution – distilled & highly pure – in amber glass with pipette

CDL is extremely versatile and highly effective. It already inspires hundreds of thousands of users in Germany.

CDL (short for chlorine dioxide solution) is a chlorine-oxygen compound which is highly effective at killing pathogens.

Chlorine dioxide solutions are approved for disinfection of drinking water according to German Drinking Water Ordinance §11.

• Our production: 
  We produce chlorine dioxide as a pure gas, in a complex process.
  Distillation process: passed into cooled water and bound therein.
  
  
• Purity:
  There are virtually no impurities present. The chlorine dioxide solution is highly pure.
  Less spicy, milder in taste and smell.
  
  
• Salary:
  The chlorine dioxide content is between 0.29 and 0.3% (2900–3000 ppm). Because chlorine dioxide gas is passed through chilled water over an extended period, the solution's concentration can fluctuate slightly. This minimal variation is negligible in practice, but it is easily recognizable by the color, which differs from the standard solution.
  
  
• Color:
  The yellow color of the distilled chlorine dioxide solution is slightly lighter than that of standard chlorine dioxide. This is due, firstly, to its high purity (no coloring impurities such as chlorine or chlorite), and secondly, to its minimally fluctuating chlorine dioxide content (between 0.29 and 0.3%).
  
  
• Durability:
  The shelf life is 9 months.

Whether produced by distillation or standard methods:
CDL is highly effective against viruses, bacteria, fungi and more.

The pathogen-killing effect is based on the natural process of oxidation. Harmful microorganisms are destroyed so quickly that their cells are unable to develop resistance to chlorine dioxide.

CDL is significantly more effective than H2O2 & chlorine.

Chlorine dioxide has been studied in scientific studies.

CDL is a chlorine-oxygen compound from which no toxic compounds can be formed during use.
After the reaction, it decomposes into oxygen, table salt and water.
The safety of the drinking water has been proven in several studies. For example, in a highly publicized placebo-controlled, double-blind study at the University of Ihio, USA.

Furthermore, it is an officially approved substance in Germany for the treatment of drinking water.

The CDL distillate is a ready-to-use solution that can be dropped directly into water.

Simply use the enclosed pipette or the dropper insert installed in the bottle.

The enclosed product description provides a simple and detailed explanation of the exact application.

In its activated state, chlorine dioxide decomposes very slowly, naturally, into table salt and oxygen.

Therefore, CDL has a shelf life of approximately 9-10 months. It should be stored in the refrigerator, ideally at a maximum temperature of 8° Celsius.

As a general rule: the colder (closer to 0°) the storage temperature, the longer the shelf life.

For bottles that have already been opened, the shelf life can vary depending on individual usage. Crucial factors include, for example, the amount of solution still in the bottle (the emptier the bottle, the more chlorine dioxide can slowly escape from the solution into the bottle), and the frequency and duration of use (the more often and for longer periods it is taken out of the refrigerator and exposed to light, the faster the chlorine dioxide can decompose).

It's important to note that CDL doesn't "go bad," but rather loses its chlorine dioxide content over time, meaning it becomes less effective. This is easily recognizable by the liquid's color. The yellow color can gradually fade over several months.

CDL bottle with pipette & product brochure.

For easy and convenient use:

The 50 and 100 ml bottles are equipped with a dropper, which you can remove from the bottle if desired.

Instead, you can use the enclosed pipette , which allows you to dose either precisely to the drop or easily and quickly using the milliliter scale (0.5 - 3 ml) .

The 250 ml bottles come with the practical pipette only. A dropper insert is not necessary.

The dropper insert and pipette are made of chemical-resistant HDPE .

Each bottle comes with a product brochure that provides simple and understandable information about CDL and its use for drinking water disinfection.
