About Prosan Chlorine Disinfectant Tablets

Prosan Chlorine Disinfectant Tablets are the safe alternative to liquid bleach (sodium Hypochlorite) and often referred to as Sodium Hypochlorite Tablets, Chlorine Tablets, Bleach Tablets or NaDCC Tablets.  Typically, 1 pot of 200 Tablets makes 1,000 Litres of HOCl Chlorine Solution at 200ppm.

  • Chlorine or Chlorination Tablets are Fast Acting, Fast Dissolving in an effervescent base.  Simply add to water to create a disinfectant solution that is ready-to-use.
  • Chlorination tablets release a stable and accurate solution of free available chlorine – perfect for due diligence
  • Drop 1 tablet into clean (potable) water to get a solution strength of 1,000 parts per million (ppm/L)
  • The 18mm diameter enables them to fit easily into a trigger spray
  • Our tablets have undergone extensive testing against:
    • EN13697 – Fungicidal Activity
    • EN13704 – Sporicidal Activity
    • EN14476 – Coronavirus
    • EN1276   – Bactericidal Activity
    • EN17126 – C.Difficile
    • EN1650  – Fungi & Yeast
  • DEFRA Approved:  This requires special label which is on our Agritabs brand
  • PN501 Prosan Chlorination Tablets contain 1.67g NaDCC which is also referred to as sodium dichloroisocyanurate and/or troclosene sodium.

NOTE:  PN501 Prosan Chlorination Tablets are equivalent to more expensive brands such as SoChlor, Actichlor, Sanichlor, Presept & Biospot.  Often, the brands disguise the product by using terminology that seems confusing – here is our guide to help:

Prosan PN501 will give the same amount of Active Chlorine as:

Actichlor 1.7g Nadcc
SoChlor 1.7g NaDcc MFB254
Presept 1.7g NaDCC – No longer Available
Sanichlor 1.7g Nadcc – Not Available
Biospot 3.25g (1.7g NaDCC)
Haz Tab H8818  1.7g NaDCC Effervescent tablets

Other brands available include: Endbac, Biochlor, Oasis, Credence 1000, Covchlor etc.  They all use the same chlorine donor and release available chlorine in water.  It’s a bit like shopping at ALDI, buy here and save £s.


Contains Sodium dichloroisocyanurate (sometimes referred to as Troclosene sodium.)  Abbreviation:  NaDCC.
When dissolved in water, the tablets produce Hypochlorous acid (HOCl or HClO).
This is an acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO.
HClO and ClO are oxidizers, and the primary disinfection agents of chlorine solutions.
