Sodium Hypochlorite Vs Hypochlorous Acid
Description Sodium Hypochlorite Hypochlorous Acid
Production Electrochemical activation of Brine through Modular electrolyzer. Electrochemical activation of Brine through Membrane electrolyzer.
Compound Description NaOCl HOCl
Alternative Name Bleach, Hypo Anolyte, Hypochlorous acid (HOCl) / Slightly Acidic Electrolyzed (SAE) Water / Electrochemically Activated (ECA) Water
Material Safety Data Sheet Statement Very hazardous in case of skin contact, eye contact, ingestion. It is an irritant and corrosive. Prolonged exposure may result in skin burns and ulcerations. Under normal usage conditions the likelihood of adverse health effects are low. The solution is recommended for treatment of infected or purulent wounds. If any irritation occurs, flush with water.
Usage level 50 ppm 0.25 ppm to 5 ppm, even 500 ppm, it is not harmful to Human or Animals.
Compound Description Yes No
Kills Legionella Yes No
Removes Biofilm & scale, eliminating hidden legionella & other bacteria No Yes
At high pH Hypochlorite ion (OCl-) Hypochlorous Acid (HOCl)
Contact time - Requires the shorted time to achieve a 99.9% kill of
Shelf-life Lye added resulting in burn potential No lye added
Biocidal Impact Only as disinfectant As disinfectant and sporicidal agent
Resistance Bacteria develops resistance to bleach due to its method of attack and residual organisms, biofilm remaining, and interaction with detergents. Bacteria does not develop a same type of resistance due to impact at cellular level destroys biofilm and no need for significant detergent use.
  • Efficient Oxidant and disinfectant.
  • Efficiently eliminates tastes and odor.
  • Featured with aftereffect.
  • Only as disinfectant.
  • Iron and magnesium oxidant. Decomposes hydrogen sulphide, cyanides, ammonium & other nitrogen compounds.
  • Strong disinfectant and oxidation agent.
  • Very effective against all kind of bacteria and virus.
  • Highly effective as a sporicidal agent.
  • Removes biofilms.
  • Significantly less formation of chlorine compounds, halogens and TMT.
  • No toxic by-products Chlorites (ClO2) & Chlorates (ClO3).
  • Very effective against all kind of bacteria and virus.
  • No acute or chronic toxicity when diluted in water.
  • Low cost. No transport or storage problem.
  • Easy and safe storage and handling.
Dis advantages
  • Strict requirements for transportation and storage.
  • Potential danger for health in case of a leak. Formation of disinfection by-products such as chloroform. The MAC in water will be increased in the near feature from 60 mkg / l up to 60 mg / l because there was no proof of direct action of the chloroform on DNA.
  • Ventilation might be required in the installation room to remove fumes.
