CDS

• CDS is the purest version of chlorine dioxide, as it is simply the gas itself dissolved in cold water (distilled if possible).
• CDS is obtained by reacting sodium chlorite with acid (preferably with 4% hydrochloric acid, although citric acid could be used if hydrochloric acid is not available, as the residue of the reaction will remain as waste). From this reaction, we will only recover the gas, which we will dissolve completely in water.
• In this way the CDS does not contain the possible residues of the unreacted material when mixed and contains only practically pure chlorine dioxide (ClO2), at least 99%.
• It produces fewer side effects, avoiding the nausea and stomach upset that can sometimes occur with MMS/CD.
• It is also absorbed more quickly in the stomach (it does not reach the intestine) and therefore does not usually cause diarrhoea.
• It is important to always keep the CDS cool, below 11 ºC, otherwise the gas will separate from the water.
• As we have already mentioned, it gasses from 11 ºC, so when the temperature of the liquid rises in the stomach, dissociation occurs (of water and gas) and the chlorine dioxide in the form of gas is absorbed through the stomach walls.

Chlorine Dioxide (ClO2)

• Chlorine dioxide or ClO2, which is its chemical formulation, is the active ingredient of MMS, CD and CDS. In the end, all three products produce chlorine dioxide gas.
• This is why we usually speak of chlorine dioxide, regardless of the form in which it is presented. Of course, there are small differences between the substances, but the main thing is that they all produce ClO2.
