Accepta EndoSan is a powerful, highly effective, broad spectrum disinfectant that is both stable and safe.

Accepta EndoSan is a solution of Hydrogen Peroxide (H2O2) which is stabilised using a proprietary ionic silver based chemistry.

When correctly applied to water, air or any surface, EndoSan will disinfect through an oxidisation process and continue to safely provide unrivalled residual performance.

Accepta EndoSan is chlorine and alcohol free, with no corrosive effects on usual materials of construction during application. After use it simply degrades into harmless water and oxygen as one of the safest forms of disinfection.

Legionella Control

The bacterium Legionella pneumophila and related bacteria are common in natural water sources such as rivers, lakes and reservoirs, but usually in low numbers. Unfortunately, given the right conditions, Legionella bacteria can prosper in purpose built water systems in any type of premises.

When water contaminated with Legionella bacteria forms small droplets suspended in the air (aerosol or vapour), there is a very high risk of inhalation and the potential contraction of Legionnaires disease.


Cooling towers, evaporative condensers, spa pools/jacuzzis, hot and cold water systems.

Systems that feature outlets like showers are particularly problematic, as water is turned to an aerosol and dispersed into the atmosphere.

Hospitals and nursing homes are higher risk as vulnerability to Legionnaires’ disease increases with age and pre-existing health issues.


A biofilm is a group of micro-organisms in which cells stick to each other and adhere to a surface. Biofilms provide bacteria a habitat that is the ideal environment for survival and replication. Additionally, the dispersal stage of the biofilm life cycle (illustrated below) enables the spread and colonisation of additional surfaces.

Biofilms can be found where:

  • Pipework that contains deposits that could provide a source of nutrient.
  • Dead legs and/or low water flow areas exist.
  • Water temperature is between 25°C and 45°C.
  • Water is stored and /or recirculated.

Product Benefits

  • No gaps – Broad spectrum high performance biocide effective against all kinds of bacteria, viruses, yeast, mould and spore formers
  • Is very effective against Legionella pneumophila
  • Environmentally friendly – practically 100% degradable breaking down to water and oxygen … (2 H2O2 = 2 H2O + O2)
  • Does not create odour or alter the taste of foodstuffs treated
  • Effectiveness and long-term effects are guaranteed even at very high water temperatures
  • Has no toxic effect in its diluted state
  • No carcinogenic or mutagenic effect
  • Does not react with ammonium-ions – no attrition
  • By adding oxygen, anaerobic conditions in the cooling water are largely avoided, thus preventing the growth of sulphate-reducing bacteria (formation of corrosive hydrogen sulphide – 4 H2 + SO42- S2- + 4 H2O)
  • Long-term effectiveness: reliably prevents recontamination
  • Toxicology: harmless, neither carcinogenic nor mutagenic
  • Storability: very long, max. loss of concentration 3% per year
  • Corrosion: very low corrosive effect
  • Measurement and regulation – complete installation programme available
  • Expenditure for equipment resp. investment costs: negligible
  • Operating costs: low


The unrivalled efficacy of Accepta EndoSan relies on its remarkable stabilisation chemistry. The silver stabiliser, which is added to the hydrogen peroxide, is a complex salt mixture formulated around ionic silver.

A silver ion is an atom of silver that is missing one electron. The outermost electrons of an atom determine the physical properties of the matter. Taking away one electron from a silver atom results in a silver ion. The ionic silver contained within Accepta EndoSan acts as a stabiliser and a catalyst, resulting in extended stability during application and giving a half-life* of up to five weeks in potable water


Accepta EndoSan is a ‘safe biocide’. After a 2 year safety study, the globally respected National Sanitation Foundation (NSF) gave approval for the continuous addition of Accepta EndoSan to drinking water supplies.

The World Health Organization (WHO), Environmental Protection Agency (EPA) and NASA have all produced documents indicating that drinking water can contain levels up to 50®ppb** silver without compromising public safety. At recommended dosing levels, Accepta EndoSan would contain less than 10ppb** of silver.


Accepta EndoSan is truly biodegradable and leaves no harmful residuals. Post disinfection, Accepta EndoSan degrades into water and oxygen, substances that are found naturally.
