The concentration of the acid as the active ingredient can vary.
Peracetic acid is a highly biocidal oxidizer that maintains its efficacy in the presence of organic soil.
Peracetic acid removes surface contaminants (primarily protein) on endoscopic tubing.
An automated machine using peracetic acid to sterilize medical, surgical, and dental instruments chemically (e.g., endoscopes, arthroscopes) was introduced in 1988.
This microprocessor-controlled, low-temperature sterilization method is commonly used in the United States.
Peracetic acid and an anticorrosive agent are supplied in a single-dose container.
The container is punctured at the time of use, immediately prior to closing the lid and initiating the cycle.
The concentrated peracetic acid is diluted to 0.2% with filtered water (0.2 mm) at a temperature of approximately 50°C.
The diluted peracetic acid is circulated within the chamber of the machine and pumped through the channels of the endoscope for 12 minutes, decontaminating exterior surfaces, lumens, and accessories.
Interchangeable trays are available to permit the processing of up to three rigid endoscopes or one flexible endoscope.
Connectors are available for most types of flexible endoscopes for the irrigation of all channels by directed flow.
Rigid endoscopes are placed within a lidded container, and the sterilant fills the lumens either by immersion in the circulating sterilant or by use of channel connectors to direct flow into the lumen(s).
The peracetic acid is discarded via the sewer and the instrument rinsed four times with filtered water.
Peracetic acid, also known as peroxyacetic acid or PAA, is an organic chemical compound used in numerous applications, including chemical disinfectant in healthcare, sanitizer in the food industry, and disinfectant during water treatment.
Peracetic acid has also previously been used during the manufacture of chemical intermediates for pharmaceuticals.
Produced by reacting acetic acid and hydrogen peroxide with an acid catalyst, peracetic acid is always sold in stabilized solutions containing acetic acid, hydrogen peroxide, and water. For the food and healthcare industries, peracetic acid is typically sold in concentrates of 1 to 5 percent and is diluted before use.
Many users know peracetic acid to be versatile and effective, and professionals with environmental responsibilities consider Peracetic acid to be environmentally friendly due to Peracetic acids decomposition products, which include acetic acid, oxygen, and water.
However, industrial hygienists recognize that Peracetic acid is also highly corrosive and a strong oxidizer, and exposure to peracetic acid can severely irritate the eyes, skin, and respiratory system.
Peracetic acid is an organic acid generated by reacting acetic acid and hydrogen peroxide.
Several commercial formulations are available.
In solution, peracetic acid dissolves and forms back acetic acid and hydrogen peroxide.
Peracetic acid is used at concentrations of 150–200 ppm on various food-contact surfaces.
Peracetic acid is efficient in removing biofilms and works well at colder temperatures.
Peracetic acid is believed to function in a similar fashion as other oxidizing agents by reacting with cellular proteins and enzymes.
In a recent study, peracetic acid at 30 mg l−1 was shown to be more efficient than 250 mg l−1 of sodium hypochlorite at removing biofilm cells of S. aureus from stainless steel and polypropylene surfaces.
Another study suggests that peracetic acid sanitizers may have some sporocidal activity against suspended bacterial spores in an aqueous solution on stainless steel surfaces.
However, sporocidal activity was minimal against spores adhering to stainless steel without the presence of an aqueous suspension.
Peracetic acid (C2H4O3) is a mixture of acetic acid (CH3COOH) and hydrogen peroxide (H2O2) in a watery solution.
Peracetic acid is a bright, colorless liquid that has a piercing odor and a low pH value (2,8).
Peracetic acid can also be produced by oxidation of acethaldehyde. Peracetic acid is usually produced in concentrations of 5-15%.
When peracetic acid dissolves in water, Peracetic acid disintegrates to hydrogen peroxide and acetic acid, which will fall apart to water, oxygen and carbon dioxide.
Peracetic acid degradation products are non-toxic and can easily dissolve in water.
Peracetic acid is a very powerful oxidant; the oxidation potential outranges that of chlorine and chlorine dioxide.
Peracetic acid can be applied for the deactivation of a large variety of pathogenic microorganisms.
Peracetic acid also deactivates viruses and spores.
Peracetic acid activity is hardly influenced by organic compounds that are present in the water.
However, pH and temperature do influence peractetic acid activity.
Peracetic acid is more effective when the pH value is 7 than at a pH range between 8 and 9.
At a temperature of 15 °C and a pH value of 7, five times more peracetic acid is required to affectively deactivate pathogens than at a pH value of 7 and a temperature of 35 °C.

Decontamination kits for cleaning fentanyl analogues from surfaces (as used by many police forces, amongst others) often contain solid peracetyl borate, which mixes with water to produce peracetic acid.
Although less active than more acidic peracids (e.g., m-CPBA), peracetic acid in various forms is used for the epoxidation of various alkenes.
Useful application are for unsaturated fats, synthetic and natural rubbers, and some natural products such as pinene.
A variety of factors affect the amount of free acid or sulfuric acid.
-Small items can be left to soak overnight in a steeping tank using Peracetic Acid 5% diluted, 3-10mls PAA per litre of water.
-Beer mains and hoses may be filled after cleaning with a diluted solution of PAA, 3-5mls PAA per litre of water and left for several hours before draining off.
