Peroxyacetic acid has a high oxidation potential and is very reactive. Peroxyacetic acid exhibits excellent bactericidal and fungicidal activity against a wide range of microorganisms in cold and warm water. Also more effective than chlorine, chlorine dioxide and quaternary products for sanitising food contact surfaces. Peroxyacetic acid helps to control spoilage or decay-causing bacteria and fungi in water that contacts raw, unprocessed fruits and vegetables. Peroxyacetic acid can be continuously sprayed, using coarse spray, or submerged using solution containing no more than 40 ppm residual Peroxyacetic Acid. Contact time of 60 seconds minimum is recommended. A final water rinse is not necessary. Compatible with most post harvest fungicides. Peroxyacetic acid is non-corrosive in its diluted form against stainless steel and aluminium surfaces. If it is to be used on other surfaces, Peroxyacetic acid is recommended that you apply product to a smaller test area to determine compatibility before proceeding with its use. Peroxyacetic acid is an organic peroxide based, colorless liquid with a low pH and a strong, pungent, vinegar-like odor. In the concentrated form Peroxyacetic acid is highly corrosive and unstable. Peroxyacetic acid is formed from the reaction of acetic acid and hydrogen peroxide.

Peroxyacetic acid can be applied by a variety of methods including spray cabinet, dip tank, hand spray pump and chiller.  Applications of Peroxyacetic Acid: Peroxyacetic acid is an excellent food grade sanitiser and also has uses as laundry bleach. Each application may require a specific dosage rate and like all oxidising biocides, soil loadings can affect required application rate. Peroxyacetic acid is biocidal at between 100 and 200 mg/L as Peroxy acetic (Peracetic) acid levels. As Peroxyacetic acid does not contain surfactants it is ideal for use in ‘clean in place’ systems as part of a no water rinse regimen when systems can be flushed with finished product (to drain) before normal production resumes. Dairies & dairy farms: When used in dairy farms, after the use of Peroxyacetic acid surfaces must be drained and thoroughly rinsed with water prior to the next milking. No rinsing: Peroxyacetic acid is an approved sanitising solution which in certain circumstances allows for use of Peroxyacetic acid on food contact surfaces without rinsing as long as drainage is available. Using Peroxyacetic acid reduces cleaning/sanitisation time and water consumption leading to lower effluent discharge costs. A versatile Peroxyacetic acid solution: In the food industry, Peroxyacetic acid is used in Cleaning in Place and Food Contact Sanitisation processes for safe, rapid microbial control.  Notably, certain food products, such as meat, poultry, fruit, vegetables and eggs, require direct protection as they can carry harmful microbes and be prone to spoilage. In addition to microbial protection, Peroxyacetic acid effectively boosts food safety by reducing the loss of goods due to fungi, viruses, algae and bacteria and enhances product quality throughout the useful shelf life and, in some cases, extends the shelf life itself.  Peroxyacetic acid is also used as a rapid high level disinfectant in the farming industry to protect animals from diseases.

Stability of the ready-to-use solution: 15 days Easy checking of Peroxyacetic acid concentration with test strips No aldehydes, safe for the user Decomposes in water and oxygen Odor of Peroxyacetic Acid: At diluted concentrations, Peroxyacetic acid is almost odorless. However, the chemical Peroxyacetic acid in concentrated form has a very strong and characteristic odor that helps users immediately distinguish it from other chemicals. Chemical Will Depend On Factors: Concentration, temperature and types of microorganisms that need to be destroyed. However, usually we use Peroxyacetic acid at a concentration of 0.05%–0.3% (mainly 0.2-0.5%). The temperature for using Peroxyacetic acid is in the range of 5–20 ºC . If Peroxyacetic acid is around 50ºC, the sterilization efficiency is higher and the sterilization time is shorter. Do not use Peroxyacetic acid at temperatures higher than 50ºC. Peroxyacetic acid at high concentrations can be stored for reuse, however, provided that they are not too dirty and additional Peroxyacetic acid chemicals must be added to ensure concentration. Because Peroxyacetic acid at high concentrations has a very strong odor, when using, mixing solutions, transporting. Lab and Field Data of Peroxyacetic Acid: Laboratory data using standard disinfectant test methods have shown that peroxygens are effective biocides against food poisoning and food spoilage microorganisms in a range of conditions representative of those in the food industry. Peroxyacetic acid has been compared with sodium hypochlorite using the European Standard Disinfectant Test. Peroxyacetic acid is effective at concentrations of active ingredient considerably lower than sodium hypochlorite, with particularly good performance against Listeria monocytogenes.  Production of Peroxyacetic Acid: Peroxyacetic acid is produced industrially by the autoxidation of acetaldehyde: O2 + CH3CHO → CH3CO3H In the presence of a strong acid catalyst, such as sulfuric acid, acetic acid and hydrogen peroxide produce Peroxyacetic acid: H2O2 + CH3CO2H ⇌ CH3CO3H + H2O However, in concentrations (3-6%) of vinegar and hydrogen peroxide marketed for household use, mixing without a strong acid catalyst will not form Peroxyacetic acid. As an alternative, acetyl chloride and acetic anhydride can be used to generate a solution of the acid with lower water content. Peroxyacetic acid is generated in situ by some laundry detergents. This is achieved by the action of bleach activators, such as tetraacetylethylenediamine and sodium nonanoyloxybenzenesulfonate, upon hydrogen peroxide formed from sodium percarbonate in water. The Peroxyacetic acid is a more effective bleaching agent than hydrogen peroxide itself. Peroxyacetic acid is also formed naturally in the environment through a series of photochemical reactions involving formaldehyde and photo-oxidant radicals. Peroxyacetic acid is always sold in solution as a mixture with acetic acid and hydrogen peroxide to maintain its stability. The concentration of Peroxyacetic acid as the active ingredient can vary. Epoxidation, Peroxyacetic acid: Although less active than more acidic peracids (e.g., m-CPBA), Peroxyacetic acid in various forms is used for the epoxidation of various alkenes (Prilezhaev reaction). Useful applications 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 (used to prepare the peracid in the first place). Peroxyacetic acid is a highly effective biocide and oxidizing agent, rapidly destroys microorganisms such as bacteria, fungi and viruses and kills pathogens. While it is extremely performant, Peroxyacetic acid is chlorine free and breaks down quickly into naturally occurring substances (water, oxygen and carbon dioxide) ౼ making Peroxyacetic acid a sustainable, environmentally friendly choice. For these reasons, Peroxyacetic acid is the ideal disinfectant across a number of different industries, namely medical, food and drink, animal biosecurity and industrial laundry.
