Peracetic acid (PAA) is highly oxidising and most potent disinfectant.
It is organic and green disinfectant. In water solution, it converts into hydrogen peroxide and acetic acid. It is a Food grade, NSF, FSSAI and Halal approved product that can be used on food contact surfaces.
It effectively kills bacteria, yeast and fungi at low temperature. It is rinse free disinfectant, hence safe to use in food and dairy sectors in CIP, surface sanitizer, equipment sanitization .

Peracetic acid (CH3COOOH) is a sustainable & and green chemical because its decomposition in water produces only water, oxygen, and easily biodegradable acetic acid. No environmentally harmful substances are produced as a result of its break down.
It is soluble in water and is completely biodegradable, breaking down into harmless products:
CH3(C=O)OOH + H2O -----------> H2O2 + CH3 (C=O)OH
Peracetic Acid Water Hydrogen Peroxide Acetic Acid
Popularity of PAA is growing which is supported by its key benefits:
Effective at low concentrations: 50- 200 ppm
Excellent performance at low temperatures
No impact on efficacy in the presence of organic matter, solids, and ammonia
Easy to use
Environmentally Friendly: No Chlorine by-products (DBP)THMs, quick breakdown, Low Aquatic Impact
Very cost-efffective if compared to other disinfection methods.
Mechanisim of Peracetic acid inactivation of microbes
Mechanism of Peracetic acid inactivation of microbes
Peracetic acid is a potent oxidizing agent. According to researchers, it can inactivates microbes in various ways:
Lea & Febiger researchers proposed that PAA operates similarly to other oxidants, targeting sensitive bonds in proteins, enzymes, and other molecules by releasing active oxygen species.
PAA interacts with double bonds, stop the functioning of molecules.
PAA alters the structure of proteins.
Some experts suggest that PAA may disrupt the chemiosmotic function of the lipoprotein cytoplasmic membrane and impact transport processes by causing rupture or displacement of cell walls.
According to Kitis, M. in "Disinfection of wastewater with peracetic acid: a review," PAA could potentially oxidize vital enzymes, disrupt biochemical processes, and impact intracellular solute levels
Oxidation Potential of Peracetic Acid
The primary mode of action is oxidation. PAA disinfects by oxidizing of the outer cell membrane of vegetative bacterial cells, endospores, yeast, and mold spores. The mechanism of oxidation is the transfer of electrons, therefore the stronger the oxidizer, the faster electrons are transferred to the microorganism and the faster the microorganism is inactivated or killed. The oxidation potential of PAA is 1.96 V which next to Ozone and better than any other disinfectants.
