NaDCC
What is NaDCC?
Sodium Dichloroisocyanurate is a form of sodium salt that is used as a source for Free Available Chlorine (FAC).
NaDCC is recommended as chemical microbicidal agent for disinfection and sterilization.
It is a popular choices for water treatment (Aquatabs) or disinfecting agent for household and hospital facilities cleaning (Klorsept or Klorkleen) . Aquatabs, Klorsept, Klorkleen are Approved by WHO and US EPA.)
NaDCC is an effective disinfectant against the Novel Coronavirus (COVID-19) – Novel Coronavirus from CDC, WHO or EPA as well as in the Coronavirus Disease 2019: Health Emergency Supply Note from UNICEF3.
NnaDCC are sold in tubs of different concentration such as Klorsept 5, Klorsept 17, Klorsept 25 or Klorsept 87 or Klorkleen in tablet form which is safe, easy to use, save space and cost-effective.
How does NaDCC work?
Once NaDCC tablet is dissolved in water, it produces free available chlorine (FAC) in form of Hypocholorous acid (HOCI) which acts as oxidizing agent. FAC is a strong and effective agent that can work against a wide range of microbes such as algae, bacteria, spores, fungi and viruses4. The active ingredient that contains microbicidal effect is four times stronger in killing microbes than hypochlorite (bleach).
Hypocholorous acid (HOCI) has a similar molecular make up as water, it can penetrate the cell wall of bacteria and viruses faster than bleach.
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
- HOCl dissociates in alkaline conditions into the hydrogen ion (H+) and hypochlorite ion (OCl-)

NaDCC has unique properties that make it a superior chlorine donor and distinctly more effective than hypochlorites:
- Close to pH neutral
- Extended residual killing power due to chemical equilibrium effect
Giving:
- Superior biocidal performance
- Protection from 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
