• NaDCC is an organic chlorine donor • NaDCC is not a hypochlorite - it has unique properties • It is a fast acting, powerful biocide • NaDCC dissolves in water to release hypochlorous acid (HOCl) and monosodiumcyanurate (a non-toxic biodegradable compound) • HOCl is the biocidal agent responsible for killing microorganisms with all chlorine products • HOCl dissociates in alkaline conditions into the hydrogen ion (H+) and hypochlorite ion (OCl-)
Superior Chlorine Donor
NaDCC has unique properties that make it a superior chlorine donor and distinctly more effective than hypochlorites:
Superior biocidal performance
Resistance to organic matter
Undissociated HOCl is 100 times more powerful than the dissociated components
Why Is HOCl 100 Times More Powerful? • HOCl has a similar chemical structure to water (HOH) • It is similar in size and it is electrically neutral • These factors enable it to penetrate the cell wall in a similar way to water
• OCl- is electrically charged, which makes it difficult to penetrate the cell wall • It is believed that, after diffusing the cell wall, HOCl destroys the proteins and enzyme systems essential to life, by an oxidation process.
Comparison of the levels of available chlorine required to achieve a 99.999% kill of Pseudomonas aeruginosa in 2 minutes at 25°C in the presence of horse serum (Coates 1988)
As the level of organic contamination increases, the solution strength required from hypochlorite to achieve the same killing power as NaDCC increases to over 4 times.
