*Chlorine-free: Contrary to the previous assumptions, not only the desired active substance chlorine dioxide is produced during the activation of classical MMS, but always also small amounts of pure chlorine. Pure chlorine reacts very aggressively with almost any reactant and there is a risk of chlorate formation. Chlorates like e.g. Weed-Ex can be in these small quantities apart from the violent smell and taste also a reason for a worse tolerance of MMS. CDS produced by distillation (from activated MMS) thus also contains small amounts of free chlorine. This free chlorine can be bound quite well by always adding at least 1 drop of DMSO to every MMS or CDS dose shortly before taking it (see chapter about DMSO). With the new CDSplus, on the other hand, the formation of pure chlorine during activation is reliably excluded by the patented process.
