The Best Defense Against Clostridium Difficile is Hypochlorous Acid
In this article I have brought together the results of several studies concerning C Difficile.
Why it is becoming resistant to current disinfects.
And what has been found to be the best way to eliminate this problem of resistant C Difficile.
A recent article in Lancet Journal, discusses the co relationship between C Difficile spore formation and hospital cleaners and disinfectants.
UK and US hospitals are struggling with a C Difficile epidemic. C Difficile is apparently generating more virulent, disinfectant resistant spore strains against the 5 most popularly hospital cleaning agents.
These new epidemic C Difficile strains produce significantly more spores than the non-prevalent strains, and sporulation is further enhanced when this strain was cultured in feces exposed to non-chlorine based cleaning and disinfecting agents.
The choice of cleaning agents has a substantial effect on the persistence of C Difficile spores in the hospital environment.
Not all C Difficile strains are created equal -
Findings suggest that these bacteria found in the hospital environment and on the hands of health care workers have been repeatedly implicated in the spread of C Difficile infections. C Difficile spores may persist in the hospital environment for months and are resistant to many commonly used cleaning agents.
Because C Difficile has been able to generate cleaning agent resistance, “deep cleaning” a hospital with common hospital cleaners can be harmful as it produces more C Difficile resistant spores.

Hypochlorous Acid Water to the Rescue –
The study above, found that spore formation of C Difficile strains can be increased by exposure to detergents commonly used when cleaning healthcare facilities.
Conversely chlorine-releasing disinfectants – such as hypochlorous acid water, did not have this negative effect on C Difficile spores.
Chlorine-releasing agents are sporicidal, unlike some other cleaning agents and have been shown to reduce rates of C Difficile infections. Thus, chlorine releasing agents, like hypochlorous acid water, are preferable when cleaning hospital areas where C Difficile contamination is likely.
Biocidal Breakthrough – Hypochlorous Acid Water
Benefits of Using Hypochlorous Acid Water over Bleach Products –
Chlorine in water splits into two forms – Hypochlorous acid (HOCI) and Hypochlorite Ion (OCI-). The more alkaline the pH of the chlorine water – the more hypochlorite or bleach it contains. The lower the pH, or more acidic, the more hypochlorous acid the water contains – the optimum pH for hypochlorous acid is between 3.0 and 6 pH.
For a chlorine solution to be a good disinfectant – it must meet the Chlorine Demand.
The Chlorine Demand is the amount of Free Available Chlorine aka Hypochlorous Acid (HCOI) needed to disinfect or oxidize organic matter. If the chlorine demand is not met, then complete disinfection is not obtained.
Efficacy is Determined by pH
The amount of chlorine in a solution is dependent on the pH level of the solution. As the pH rises, less Hypochlorous acid is available, the less germ killing power is available and more Hypochlorite Ion is available in the solution. The lower the pH or more acidic the solution, the more hypochlorous acid is available to kill pathogens.
Hypochlorous Acid (HOCI) is 120 times more effective as a sanitizer
According to the University of Illinois study, Hypochlorous Acid (HOCI) is 120 times more effective as a sanitizer than Hypochlorite (OCI-). The ideal pH of a disinfecting chlorine solution is between 3 and 6 pH. Bleach has a pH of about 10.25 producing NO HOCI or Hypochlorous acid at all.
Commercial bleach has an unknown chlorine content. These types of bleach and lye type products are hazardous as they burn tissues and are dangerous to inhale.
FDA Approves Hypochlorous acid water as GRAS -
Hypochlorous acid solutions have been FDA, EPA and USDA approved as GRAS or Generally Regarded As Safe or has no harmful effects.
The Center of Disease Control has also deemed:
“the microbicidal activity of a new disinfectant, “superoxidized water,” (aka hypochlorous acid water) has been examined. The concept of electrolyzing saline to create a disinfectant or antiseptics is appealing because the basic materials of saline and electricity are inexpensive and the end product (i.e., water) does not damage the environment.”
The correct pH value of “Hypochlorous acid water can inactivate Clostridium difficile spores in <10 minutes”.
“In October 2002, the FDA cleared superoxidized water (aka hypochlorous acid water)as a high-level disinfectant”.
“Superoxidized water” (aka hypochlorous acid water) has been tested against bacteria, mycobacteria, viruses, fungi, and spores 537, 539, 549. Freshly generated superoxidized water (aka hypochlorous acid water)is rapidly effective (<2 minutes) in achieving a 5-log10 reduction of pathogenic microorganisms (i.e., M. tuberculosis, M. chelonae, poliovirus, HIV, multidrug-resistant S. aureus, E. coli, Candida albicans, Enterococcus faecalis, P. aeruginosa) in the absence of organic loading.”

Bleach or hypochlorite is proven to be a very poor disinfectant. Bleach also has a self life. As the chlorine escapes, the bleach solution weakens in its germ killing ability.
Having an onsite hypochlorous acid water processor from Team 7 Waters, provides hospitals and healthcare facilities with the best of all options:
- Fresh, potent hypochlorous acid water
- The pH can be accurately set and controlled to the level needed anywhere from 2.5 to 11.5 pH
- Fresh hypochlorous acid water will do the best job at eliminating pathogens including C Difficile
- Hypochlorous acid requires the shortest contact time to eradicate microorganisms
- An onsite, internal computer controlled Hypochlorous acid water processor requires no need for mixing and the dilutions is the same every time
- Simple & easy to use – Push button panel allows the customized control of pH & Hypochlorous acid
- No harmful preservatives which are include in prepackage hypochlorous acid products
- No shelf life problems
- No expired products
- Cost effective and Inexpensive:
- No wasted money on expired products
- Only pennies a gallon – less than a dime a gallon
Team 7 Waters is proud to offer a cost effective solution to getting control over a C Difficile problem for good. At the same time, hospitals and healthcare facilities can get and stay compliant with Medicare and Medicaid participating provider regulations regarding healthcare associated infection rates.
