viruses with a log 4, this is a 10,000-fold reduction. 


What is Challis Ag+ EndoSan exactly?

Challis Ag+EndoSan is a unique formula of hydrogen peroxide which has

been stabilised and catalysed by the addition of a small quantity of silver.


How does Challis Ag+ EndoSan Work?

Individually neither hydrogen peroxide nor silver are particularly very good water system disinfectants when used individually, the combination produces a superbbiocide. The mechanism is thought to be as follows:

Hydrogen peroxide is not very effective against bacteria because these micro-organisms can secrete catalase which reacts with hydrogen peroxide preventing it from reaching the cell wall and destroy the bacterium/virus. Therefore, if hydrogen peroxide is used alone a huge quantity is required. This is where the silver plays an important role. The silver emits electrostatic which de-stabilise the bacteria/virus defence system (catalase enzyme) and allow the hydrogen peroxide to attack and destroy the virus/bacteria. When the virus/bacterium is dead, it is no longer attracted by the silver which moves back into the bulk water pulling the hydrogen peroxide behind it. This makes the solution very stable. The product also effervesces which is an indicator of its effectiveness.

Challis Ag+ EndoSan is a unique formula and has gotten approvals from different organisations and governmental agencies worldwide in the past 25 years and is already in use in NHS Trusts across the country.

Challis Ag+ EndoSan provides 99.9% disinfecting ability as documented by

scientific researches and laboratory tests worldwide.
