The first step of Pure Maintenance’s two-step process is called the InstaPURE process. This is a powerful disinfectant process that destroys mold and pathogens throughout your space. The process reduces the mold-load to nearly zero and kills all pathogens so you can breathe a healthy sigh of relief. The InstaPURE process is such a strong and effective disinfectant; it disinfects any surface it touches.
Step 1: The InstaPURE Process
Understanding the Chemistry of the InstaPURE Process
It is important to understand the chemistry of the InstaPURE process and its amazing ability to perform like a cold sterilant. Peracetic Acid is an organic compound produced by reacting acetic acid, a component of vinegar, and hydrogen peroxide. This creates an equilibrium mixture of acetic acid, hydrogen peroxide, and peracetic acid. The vapor contains all three of these compounds. Here are a few interesting bullet points of InstaPURE, i.e. Peracetic Acid.
- Peracetic acid is also known as peroxyacetic acid or PAA.
- THE EPA FIRST REGISTERED PERACETIC ACID AS AN ANTIMICROBIAL IN 1985.
- Use sites include agricultural premises, food establishments, medical facilities, and homes. It is also registered for use in dairy and cheese processing plants, food processing equipment, and pasteurizers in breweries, wineries, and beverage plants.
- Peracetic acid is also used as a chemical disinfectant in healthcare, a sanitizer in the food industry, a purifier in water treatments, and dialysis equipment, and of course in vapor form by Pure Maintenance.
- The InstaPURE process’ Vapor destroys microorganisms by Lysis. (tearing open the cell wall)
- Killing microorganisms by Lysis prevents cells or spores from creating resistant mechanism defense.
- This process (if fogged correctly) produces dramatically increased vapor pressure. As a side note, Hydrogen Peroxide vapor has very little vapor pressure. In other words, HPV is adequate at killing microorganisms that the vapor lands on, however, it is not good at finding microorganisms in cracks and crevices of a home or facility or pushing itself to various heights of a ceiling.
- Peracetic acid is 1 of only 7 antimicrobials listed by the EPA as a SAFER CHOICE
- Chemical. It is alongside things such as sodium bisulfate, citric acid, and H2O2.
- The InstaPURE process breaks down to oxygen, water and acetic acid. Re-entry is usually allowed within 2 hours post treatment. We direct measure the PAA vapor and hydrogen peroxide vapor with a gas sensing direct measurement device to ensure PPM levels are at or below 0.5 and 0.4 respectively so as to confirm the safety of re-entry into the space.
Understanding the Science
Synergistic Behavior with Acetic Acid and Hydrogen Peroxide?
Peracetic acid solutions also contain hydrogen peroxide. PeroxyChem’s VigorOx® WWT II PAA solution contains 15% PAA by weight, but also 23% hydrogen peroxide. It is believed that the predominant disinfection comes from the peracetic acid, as PAA is a much more potent antimicrobial agent than hydrogen peroxide, especially at low concentrations. Several research studies have shown that there are virtually no synergistic effects between the PAA and hydrogen peroxide. However, several investigations suggest that there may be enhanced microbial efficiency due to a potential efficacious synergy in PAA and hydrogen peroxide. These investigations compared solutions containing “pure” PAA, hydrogen peroxide only and commercially available combinations of both PAA and hydrogen peroxide.
The results suggest that the kinetic model of combined PAA and hydrogen microbial inactivation occurs in a staged process, including sensitization, catalase attack and irreversible attack leading to lysis. These works indicate that PAA must first initiate the attack on the cell, damaging the protective systems before the hydrogen peroxide can participate in actively in the bacterial inactivation reaction, and that once the catalase within the microorganism is inhibited by PAA, the hydroxyl radical can rapidly damage the cell.
*Pre-cleaning of all surfaces is required before any treatments. Post treatment cleaning protocols should remain a best practice.
