WATER PURIFICATION TABLETS: 2ND PLACE PRODUCT OF THE YEAR. Hydrozone's innovative, hypochlorous acid tablets utilize revolutionary technology that makes available the highly effective sanitizing benefits of hypochlorous acid in a simple to use tablet form. The tablets are wrapped and specially engineered to carefully control and sustain the release of specified concentrations and strengths of hypochlorous acid when added to water. Generating hypochlorous acid with these tablets is simple as in their dry form, the tablets are un-reactive only producing hypochlorous acid when exposed to or added to water. To activate the tablets simply take the tablet's orally with a glass of water and within seconds they act to produce a solution of activated hypochlorous acid in the stomach. This generated solution is effective for microbiological control oxidation.

Relevant Scientific Data and Technical Information

Sodium Dichloroisocyanurate (NaDCC) MMS2

Chlorine Release

Solutions of NaDCC release "free" available chlorine (av.Cl2) in the form of HOCl (Hypochlorous acid) and OCl (Hypochlorite), in 50:50 equilibrium with the "combined" available chlorines, mono- and dichloroisocyanurate. According as the free chlorine becomes used up by micro-organisms and organic matter etc., the combined will release further free av.Cl2 to restore the 50:50 balance. This will continue with increasing demand until no further chlorine remains available. This is a unique phenomenon among chlorine donor compounds and explains:

a) The greater biocidal capacity of NaDCC;

b) Why NaDCC is less toxic and less corrosive; and

c) Why NaDCC solutions persist for much longer, and in an active state.

Lethal Biocide Action

It is generally believed that the antimicrobial activity of NaDCC is due to chlorination of cell protein or enzyme systems by free HOCl, causing hydrolysis

of the peptide chains of the micro-organisms' cell membranes.

Effect of pH

pH has probably the greatest influence on the disinfectant activity of all chlorine solutions and the HOCl ion is responsible for the microbiocidal activity of NaDCC solutions. Hypochlorous acid dissociates eventually as follows:- HOCl to H+ + OCl- ; with HOCl possessing 100 times greater potency than OCl (hypochlorites).

This Dissociation of HOCl is critically pH dependent:

At pH5: abt. 99.7 % HOCl is released from solutions of NaDCC. At pH7 (Pure Water): abt. 72.3% At pH 9.5 (average for sodium hypochlorite solutions) a mere 0.19% HOCl is yielded up.

This helps to explain the significant advantage in microbiocidal activity of NaDCC based products over all other chlorine donors.

It is important to remember that:-

NaDCC products are active over a pH range of 5.0 - 6.5.

They differ totally from hypochlorites and chloramines Hypochlorites (bleach) and Chloramines are effective only at alkaline pH (av. 9.5), releasing minimal or relatively low levels of HOCl compared to NaDCC-based compounds.

NaDCC products release highly significant levels of HOCl.

Therefore they are:

a) More effective

b) less toxic and less corrosive than other chlorine compounds, with

c) rapid HOCl release

d) rapid biocidal activity

e) no skin irritation.

Smell  The faint, characteristic "chlorine" smell from all NaDCC solutions is due to the release of chloramines (breakdown products of NaDCC). The scent becomes more pronounced as organic substances like skin, micro-organisms or any organic contamination load come into contact with NaDCC solutions.
