In a question-and-answer format, here are some more facts we should know about quats.
In an earlier post, we discussed an issue that building owners and managers should be aware of as we work together to help stop the spread of the coronavirus. The issue is quat binding. Very simply, quat binding occurs when the key ingredient in many disinfectants—quaternary ammonium chlorides, also known as quats—become absorbed into the cleaning wipes.
This most frequently occurs when cotton and paper-based wipes are used on surfaces. It does not happen as often when microfiber wipes are applied, because they are made with synthetic materials that help prevent quat binding from occurring. That is one reason why at Secure Clean, our cleaning workers always use microfiber cleaning cloths.
However, we did not want to give the impression that quats are bad. They are a typical formulation used for years in a variety of sanitizers and disinfectants. They help us eliminate disease-causing pathogens from both porous and nonporous surfaces; they’re one of the best tools we use to keep people healthy.
In a question-and-answer format, here are some more facts we should know about quats:
Are they safe?
Disinfectants in the United States are classified as “pesticides.” This means they are designed to kill—eliminate—germs, bacteria, viruses, and other pathogens on surfaces. However, if used properly, they are safe. The Environmental Protection Agency (EPA) tests disinfectants used in this country. If a disinfectant is EPA-registered, it has been tested and approved to eliminate pathogens as the manufacturer claims and is safe to use if used per the manufacturer’s instructions.
How long have they been used?
Earlier, we mentioned they have been used for years. Let’s revise that. They have been used for more than a century, making them one of the oldest cleaning tools we have.
How do they work?
As we mentioned earlier, the quat molecules are positively charged. Most forms of bacteria and other pathogens are negatively charged. The quat molecules attach to the membranes of the pathogens and start to dissolve them. Additionally, some quat disinfectants bind to pathogens and prevent their normal functions such as reproducing. This also helps eliminate them.
Do they do this with all pathogens?
On the label of all disinfectants, including quat disinfectants, are “kill claims.”
This is a list of the types of germs, bacteria, and viruses the disinfectant is designed to eliminate. If the concern is eliminating MRSA on a surface, for example, the user would need to select a disinfectant that, according to the manufacturer’s kill claims, is designed to eliminate these bacteria.
Do they work like antibiotics?
Yes, in the fact that antibiotics and disinfectants are designed to eliminate pathogens. However, antibiotics are medications and are safe to ingest. Disinfectants are for cleaning and can cause serious harm if swallowed.
Are quats harmful to the environment?
Quats are biodegradable. Eventually, the active ingredients in quat disinfectants evaporate and breakdown. However, if misused, they can be harmful to the user and the environment.
Where are quat disinfectants most used?
They are used in all forms of cleaning and disinfecting. They are not only one of the oldest but one of the most effective cleaning tools we have today.
How can we prevent quat binding?
One of the key ways we have to help prevent quat binding at Secure Clean is by using microfiber cleaning cloths when disinfecting surfaces.
“Microfiber is very effective at removing germs and bacteria when you’re disinfecting,” says Jonathan Cooper, director of environmental and linen services at Orlando Health Central Hospital, Ocoee, Florida. “It also eliminates the problem of quat binding, which occurs when fabrics attract the active ingredients in quat-based disinfectants. This is a big problem with cotton and paper wipes, but not microfiber.”
