New: Minncare Sporicidal Disinfectants & Foggers

Mar Cor Cold Sterilants: Use & Decontamination

Minncare and Actril are two examples of cold sterilants used for endoscope, dialysis, and cleanroom disinfection. Cold sterilants provide non-invasive sterilization of dental/surgical equipment such as pressure clamps, tubing clamps, blood pressure cuffs, mirrors, etc. 

In tandem, they work against a broad spectrum of organisms, including bacterial spores, fungal spores, bacteria, mycobacteria, yeast, molds, and viruses. Neither are used for terminal sterilization on critical or semi-critical medical applications. Both are authorized as Class A sterilants by the EPA. 

An aldehyde-free formulation prevents toxic exposure to aldehyde vapors and poses no threat to municipal waste treatment systems. While it should be handled with care in its concentrated form, it doesn’t require extraordinary handling procedures or ventilation systems. It is completely biodegradable, does not produce toxic vapors, and will decompose into oxygen, water, and acetic acid. Acetic acid is the active ingredient in vinegar.

Cold Sterilant Cleaning Solutions

Minncare Cold Sterilant is a powerful disinfectant containing a mixture of 4.5% peracetic acid and 22.0% hydrogen peroxide. The peracetic acid solution is one of the fastest acting and most effective disinfectants available. It’s a powerful oxidizer that destroys the structure of microbes and prevents contamination for reverse osmosis (RO) membranes and their associated distribution systems.
Actril Cold Sterilant is designed for hard surfaces common in biopharmaceutical facilities, therefore it’s ready to use and pre-diluted. It maintains compatibility with most materials found in modern cleanrooms. The Atricil formula is eco-friendly because its raw materials are not characterized as carcinogenic, mutagenic materials, or toxic. It’s safe for the environment and is completely biodegradable and will decompose into oxygen, water and acetic acid.

Beyond its use in medical device manufacturing, it is also appropriate for poultry processing plants, canneries, dairies, breweries, wineries, including food and beverage facilities.

Cold Sterilant Application and Dispersion Foggers

For medical device and healthcare practices, the approach to disease and infection control is multifaceted. Gas-based sterilization methods often require long periods of downtime for the facility to outgas and filter harmful aerosols and particles that can remain suspended in the air for days at a time. A full kill of all microbes that don’t require partial or facility-wide evacuation may not have the same efficacy,

Disinfecting large areas with precision and a high degree of microbial count reduction (log reduction) is challenging. Each type of disinfectant/sporicidal agent has its advantages and falls backs. Chemicals aggressive enough to kill fungal and bacterial spores often produce hazards, such as exposure to carcinogens gases, respiratory irritation/damage and chemical burns. If technicians must apply cleaners and solvents by hand, they face unnecessary exposure. 

Minncare Dry Fog Systems

Dry foggers produce droplets as small as 7.5 microns which reduce condensation, surface wetting, and possible corrosion. Area coverage is more uniform and the fog penetrates cracks, crevices, ventilation systems and other challenging areas like high corners and underneath furniture.

Dry Fog systems provide a faster, easier, and more cost-effective solution for decontamination, endoscopy, dialysis and instrument sterilization. It’s an emerging technology that fast-tracks decontamination routines in cleanrooms, laboratories, and healthcare facilities.

  • 95% faster than conventional systems
  • Substantially less cleanroom downtime
  • Eliminates formaldehyde disinfection

Titanium and 316L stainless steel components allow rapid setup and breakdown for autoclave sterilization. The portable system is easily used in multiple locations. Specially formulated cold sterilants neutralize spores, bacteria, mycobacteria, yeast, molds, and viruses without applying heat. Its sanitary and autoclavable design permit use in the most critical areas and maintain the utmost levels of sterility. Beyond biotechnology, pharmaceuticals, and other controlled environments, cleanroom dry foggers also curb bio-burdens within agricultural, beverage, and food processing applications.

What Microorganisms and Pathogens Are Peracetic Solutions Effective Against?

  • HIV
  • Hepatitis B
  • Bacillus subtilis.
  • Mycobacterium bovis (TB surrogate)
  • Pseudomonas aeruginosa
  • Salmonella typhimurium

MSSA — Methicillin-susceptible S. aureus. This is the regular (non-resistant) strain of S. aureus.

MRSA – Methicillin-resistant S. aureus, which today refers not only to just strains that are methicillin-resistant, but also any beta-lactam antibiotic, such as amoxicillin and penicillin.

HA-MRSA – a MRSA infection acquired during a stay in or immediately after discharge from a hospital or other healthcare setting.

CA-MRSA – Community Acquired-MRSA – an infection with MRSA in a person who does not have any prior history of health care exposure such as hospitalization, surgery or a permanent intravenous lines or other indwelling devices or hemodialysis.

Less Invasive with Faster and More Complete Microbial Kill Rates

Methicillin-sensitive Staphylococcus aureus, or MSSA, is a problematic bacterium and one of the most common vectors of infection within healthcare environments. Cold Sterilant and 1% Minncare Solution pass the modified AOAC Use-Dilution Method for MSSA at 3 minutes, with a 6 log reduction in organisms. At one minute, both disinfectants reported 80% reduction or better of the carriers and a total kill of MSSA . For MRSA, both disinfectants passed the modified AOAC Method at two minutes, provided a 7 log reduction of organisms on all the carriers. The efficacy of these sterilants is studied and documented.

Demystifying Cleanroom Foggers

Dry foggers provide economical fogging solutions for smaller facilities of up to 900 sq. ft. and full-scale systems for facilities as large as 35,000 sq. ft. Every cleanroom application is different. Because these systems improve outcomes for operators and environments, they are used in limitless applications from agriculture and food processing to sterile bio-medical environments.
