Does hydrogen peroxide kill good bacteria

As more information about the coronavirus pandemic develops, some of the information in this story may have changed since it was last updated. Killing germs on household surfaces is nothing new. You're probably already doing it when you routinely clean the bathroom and after you handle raw meat or chicken in the kitchen. But with this current outbreak of the Novel Coronavirus COVIDkeeping all frequently-touched household surfaces, like faucet handles, phonesand remote controls, germ-free is more top-of-mind than ever.

It's important to know that not all cleaning products that claim to disinfect are equally effective on all types of germs. There are many types of bacteria and viruses and not every product kills them all.

Below, we list which products specifically work on the coronavirus, how to properly use them for maximum effectiveness ā€” and which to avoid. The U. Environmental Protection Agency EPA has compiled a list of products that while not specifically tested on the brand-new version of the virus that causes COVID just yet, have been proven effective on similar or harder-to-kill viruses, such as the rhinovirus that causes the common cold; they expect them to work on the coronavirus, too.

These products use a variety of different ingredients and formulations, so be sure to use them exactly as the label directs. These products include:. Before using any sanitizing or disinfecting product, start by reading the label to make sure it is registered with the EPA and to see what strains of bacteria and viruses it kills. The EPA registration number can usually be found in small type on the bottom of the front or back label, and the bacteria and viruses the product is effective against are also usually listed.

EPA registration is required by law for any cleaner that claims to kill germs. It's what we rely on in the Good Housekeeping Cleaning Lab when we evaluate sanitizing and disinfecting products and it assures you that if you follow the directions, the product will work as claimed. According the the U. For small batches, use 4 teaspoons of regular chlorine bleach and 1 quart of water. To use: Wearing gloves, dip a cloth into the mixture, wipe the surface, allowing the solution to contact the surface for five minutes and air dry.

Rinse all surfaces, including food contact surfaces, like countertops and high chair trays, with warm water and air dry after disinfecting. Be careful not to splash the bleach solution on your clothes or in your eyes and use it sparingly on stainless steel sinks and surfaces.

It's also important to note that the bleach and water solution needs to be made fresh each day you use it.

According to the CDC, hydrogen peroxide is a stable and effective disinfectant against a wide variety of microorganisms, including bacteria and viruses, when used on hard, non-porous surfaces.

It's best to keep it away from fabrics when cleaning and to wear gloves to protect your hands. To use : Spray or wipe it on the surface, allowing it to remain wet for at least one minute before wiping. To use: Wipe or spray the surface with the alcohol and make sure it remains wet for at least 30 seconds. According to the CDC and NSF a public health and safety organizationvinegar or vinegar-based alternative cleaning products should not be used to disinfect or sanitize.

Vinegar-containing cleaning products can be a good in some instances, but vinegar is not registered with the EPA as a disinfectant and is ineffective against most bacteria and viruses ā€” it does not kill the flu or coronavirus. Undiluted white vinegar may work on some limited types of bacteria, but it's not the best way to get surfaces germ-free. Besides, coronavirus is a virus, not a bacteria. Product Reviews.

Hydrogen peroxide H2O2a compound made up of two hydrogen atoms and two oxygen atoms, begins to breaks apart as soon as it contacts blood, creating that stinging sizzle. This is because blood and most living cells contain the enzyme catalase, which attacks hydrogen peroxide and converts it into water H2O and oxygen O2. Hydrogen peroxide has been used as an antiseptic since the s because it kills bacteria cells by destroying their cell walls.

This process is called oxidation because the compound's oxygen atoms are incredibly reactive, and they attract, or steal, electrons. With fewer electrons, bacteria cells' walls become damaged or even completely break apart. Unfortunately, hydrogen peroxide's oxidation also destroys healthy skin cells. This is why many physicians and dermatologists currently advise against using hydrogen peroxide to clean woundsas it has been found to slow the healing process and possibly worsen scarring by killing the healthy cells surrounding a cut.

Despite its negative effect on healthy cells, our bodies' cells naturally produce hydrogen peroxide when we metabolize food and turn it into energy.

So how can a cell produce something that can destroy its own walls? That's where catalase steps in: when a cell creates hydrogen peroxide, it stores it inside the cell's specialized organelles, called peroxisomes, which contain hydrogen peroxide-busting catalase. Inside of a peroxisome, hydrogen peroxide decomposes and is turned into harmless water and oxygen gas. Catalase is present in the cells of nearly all living organisms, so next time you want to amuse the kids with a fun science trick, pour some hydrogen peroxide on half of a raw potato and watch it fizzle.

As a young child, I remember my mom would rush to get the hydrogen peroxide to wash out our cuts and burns. The blood and other living cells found in a wound use the catalase enzyme to attack the hydrogen peroxide and convert it to water H2O and oxygen O2.

In its low concentration, hydrogen peroxide will start a bubbling action which helps remove debris from the wound and work to kill bacteria cells by destroying their cell walls.

Here is where it all gets tricky. Although hydrogen peroxide is thought to be a good first aid antiseptic, the controversy remains on how beneficial it actually is in the long run. As a wound care specialist, I see wounds all the time that are stuck in a certain phase of wound healing and the wound struggles to progress forward.

What it comes down to for me is giving the wound the best chance possible at healing and ultimately wound closure. After years of research, we now know that the caustic nature of hydrogen peroxide and rubbing alcohol another commonly used first aid antiseptic can destroy healthy cells and therefore affect wound healing. If peroxide is used, it is definitely not recommended on a long-term basis. The bactericidal effects of the hydrogen peroxide are great to clean the wound and kill bacteria initially, but this same benefit comes with a price in that the peroxide can damage skin cells and angiogenesis which is the process of new vessel formation.

So for me, the benefits do not outweigh the risks. I see a lot of complex and chronic wounds and it is my job to not only determine the wound etiology but also deduct all aspects of what may be causing the wound to not improve, as well as manage everything that may delay wound healing. People on certain medications will have delayed wound healing potential as well as people with other co-morbidities such as rheumatoid arthritis and diabetes.

These individuals are starting the wound healing cascade already impeded by low healing potential, so pouring hydrogen peroxide on their wounds even initially can drastically affect their chance of ever healing.

For diabetic patients, especially after a skin injury, the odds of healing not only stack up against you but they do so quickly. My approach has always been to take all steps possible to heal wounds in the shortest amount of time and to decrease the risk of infection which may lead to delayed wound healing, and in some individuals limb loss. So the question is not whether hydrogen peroxide is beneficial.

That is not up for debate - there are many good uses for it, just not on wounds. Wounds can instead be cleaned with mild soap and water immediately after an injury.

On a long-term basis, there are a myriad of wound cleansing options available which will help to remove biofilm and reduce bioburden in the wound but not affect the healthy skin cells. Allowing the proliferation of fibroblast cells in the wound cells that play an important role in forming new granulation tissue and getting the wound healed.

Although the debate on the effectiveness of using hydrogen peroxide on wounds may continue, one thing that is certain is wound care has grown so much especially over the past 20 years. There are many advanced wound care modalities available, many of which we provide at the Davis Regional Medical Center Wound Healing Center.

CEO's Message.This coronavirus seems to spread most commonly from person to person via respiratory droplets, according to the U. Transmission of the virus from contaminated surfaces has not yet been documented, the CDC notes, but current evidence does suggest the virus can remain viable "for hours to days on surfaces made from a variety of materials. To disinfect surfaces, the CDC recommends a household bleach or alcohol solution see below for detailsand points to a list of disinfectant products registered by the U.

Bleach is a relatively cheap and highly effective disinfectant. It kills some of the most dangerous bacteria, including staphylococcus, streptococcus, E.

It should also work on the novel coronavirus, according to the CDC, which notes that "unexpired household bleach will be effective against coronaviruses when properly diluted. While bleach can be an important disinfectant in some situations, though, it's also a potential hazard to human health, capable of not only irritating sensitive tissue in the eyes, skin, mouth and throat, but also contributing to long-term respiratory problems like asthma.

Bleach can also be hazardous to pets, wildlife and ecological health. There are some safer alternatives in disinfecting wipes and cleaning sprays, although these eco-friendly choices may not be as effective in killing bacteria and viruses.

Will hydrogen peroxide kill all flu germs?

Also note that both bleach and bleach alternatives are intended to disinfect surfaces, and should not be used on the skin, and that bleach should never be combined with ammonia or ammonia-based cleaners. Don't just run your hands quickly under the water. Regular soap and water clean germs away rather than killing them, but that's still a key step in reducing infection, the CDC points out. Washing your hands with soap and water is one of the main recommendations for limiting the spread of the novel coronavirus, since it seems to spread primarily from person to person via respiratory droplets, which are often found on our hands and easily transferred to our faces.

Store shelves are also filled with products that boast antimicrobial properties, including antibacterial soap.

There is a common misconception, however, that antibacterial soap is effective in eradicating all germs. Although antibacterial soap may kill some bacteria, there is little evidence that it's more effective than regular soap, and it offers no additional protection from viruses. In fact, many health experts advise against using antibacterial products, as many contain a potentially harmful ingredient called triclosanwhich some research suggests is an endocrine disrupter.

Moreover, overuse of these products may contribute to antibiotic resistance and the rise of so-called superbugs.

Although it may be a more environmentally friendly cleaning solution than many other products, ammonia is not registered as a disinfectant by the EPA. Ammonia might kill salmonella and E. And remember never to mix ammonia with bleach.

Alcohol-based hand sanitizers can work against many bacteria and some viruses. Alcohol has long been used as an antiseptic. Ethyl alcohol in particular is effective against a wide range of bacteria, and also some viruses, namely those known as "enveloped viruses. Alcohol may not be helpful, however, against viruses that lack this envelope, such as norovirus.

The U. Food and Drug Administration FDA has warned the makers of some hand sanitizers against claiming their products can prevent infections like the flu, citing inadequate evidence. If you buy hand sanitizer, avoid products that contain triclosan. As an alternative to buying it, you could also make your own hand sanitizer at home. Vinegar can be used as a safer bleach alternative for some applications, such as cleaning, and research has shown it can be affective against some bacteria and viruses, including the flu.

It is also biodegradable. Vinegar is not a registered disinfectant, however, and does not kill dangerous bacteria like staphylococcus.

Hydrogen peroxide has antimicrobial properties and can be an effective household cleaner.FDA has not cleared any liquid chemical sterilant or high-level disinfectant with alcohol as the main active ingredient.

These alcohols are rapidly bactericidal rather than bacteriostatic against vegetative forms of bacteria; they also are tuberculocidal, fungicidal, and virucidal but do not destroy bacterial spores. Top of Page. The most feasible explanation for the antimicrobial action of alcohol is denaturation of proteins. This mechanism is supported by the observation that absolute ethyl alcohol, a dehydrating agent, is less bactericidal than mixtures of alcohol and water because proteins are denatured more quickly in the presence of water Protein denaturation also is consistent with observations that alcohol destroys the dehydrogenases of Escherichia coliand that ethyl alcohol increases the lag phase of Enterobacter aerogenes and that the lag phase effect could be reversed by adding certain amino acids.

The bacteriostatic action was believed caused by inhibition of the production of metabolites essential for rapid cell division.

Methyl alcohol methanol has the weakest bactericidal action of the alcohols and thus seldom is used in healthcare The bactericidal activity of various concentrations of ethyl alcohol ethanol was examined against a variety of microorganisms in exposure periods ranging from 10 seconds to 1 hour Isopropyl alcohol isopropanol was slightly more bactericidal than ethyl alcohol for E. Isopropyl alcohol is not active against the nonlipid enteroviruses but is fully active against the lipid viruses Studies also have demonstrated the ability of ethyl and isopropyl alcohol to inactivate the hepatitis B virus HBVand the herpes virus, and ethyl alcohol to inactivate human immunodeficiency virus HIVrotavirus, echovirus, and astrovirus In tests of the effect of ethyl alcohol against M.

InSpaulding stated that alcohols were the germicide of choice for tuberculocidal activity, and they should be the standard by which all other tuberculocides are compared. The mucin-loop test is a severe test developed to produce long survival times. Thus, these figures should not be extrapolated to the exposure times needed when these germicides are used on medical or surgical material Alcohols are not recommended for sterilizing medical and surgical materials principally because they lack sporicidal action and they cannot penetrate protein-rich materials.

Fatal postoperative wound infections with Clostridium have occurred when alcohols were used to sterilize surgical instruments contaminated with bacterial spores Alcohols have been used effectively to disinfect oral and rectal thermometers, hospital pagersscissorsand stethoscopes Alcohols have been used to disinfect fiberoptic endoscopesbut failure of this disinfectant have lead to infection Alcohol towelettes have been used for years to disinfect small surfaces such as rubber stoppers of multiple-dose medication vials or vaccine bottles.

Furthermore, alcohol occasionally is used to disinfect external surfaces of equipment e. In contrast, three bloodstream infection outbreaks have been described when alcohol was used to disinfect transducer heads in an intensive-care setting The documented shortcomings of alcohols on equipment are that they damage the shellac mountings of lensed instruments, tend to swell and harden rubber and certain plastic tubing after prolonged and repeated use, bleach rubber and plastic tiles and damage tonometer tips by deterioration of the glue after the equivalent of 1 working year of routine use Tonometer biprisms soaked in alcohol for 4 days developed rough front surfaces that potentially could cause corneal damage; this appeared to be caused by weakening of the cementing substances used to fabricate the biprisms Corneal opacification has been reported when tonometer tips were swabbed with alcohol immediately before measurement of intraocular pressure Alcohols are flammable and consequently must be stored in a cool, well-ventilated area.

They also evaporate rapidly, making extended exposure time difficult to achieve unless the items are immersed. Hypochlorites, the most widely used of the chlorine disinfectants, are available as liquid e. The most prevalent chlorine products in the United States are aqueous solutions of 5. They have a broad spectrum of antimicrobial activity, do not leave toxic residues, are unaffected by water hardness, are inexpensive and fast actingremove dried or fixed organisms and biofilms from surfacesand have a low incidence of serious toxicity Sodium hypochlorite at the concentration used in household bleach 5.

The microbicidal activity of chlorine is attributed largely to undissociated hypochlorous acid HOCl. A potential hazard is production of the carcinogen bis chloromethyl ether when hypochlorite solutions contact formaldehyde and the production of the animal carcinogen trihalomethane when hot water is hyperchlorinated After reviewing environmental fate and ecologic data, EPA has determined the currently registered uses of hypochlorites will not result in unreasonable adverse effects to the environment Alternative compounds that release chlorine and are used in the health-care setting include demand-release chlorine dioxide, sodium dichloroisocyanurate, and chloramine-T.

The advantage of these compounds over the hypochlorites is that they retain chlorine longer and so exert a more prolonged bactericidal effect.Hydrogen peroxide is a reliable disinfectant that has the highest effect for up to thirty minutes, when applied in temperatures of about twenty degrees Celsius, according to the CDC.

Overall, it can keep the treated surface-sterilized for over six hours, and it is advisable to reuse the product after twenty-one days. The product is effective against a wide range of microorganisms, and it works through the production of destructive hydroxyl free radicals. This chemical compound has a shelf life of two years, with zero disposal restrictions, and can be used on many materials.

However, proper storage measures are required to ensure the product remains stable for long. Also, it is required to wear eye protection gear when using the product, as it is a serious irritant.

Are you wondering how the hydrogen peroxide disinfection process works? When and how to use it?

Let me help you to learn more about this disinfector. The product has been in use for ages, although initial applications included treatment of cuts. However, researches now show that hydrogen peroxide kills healthy cells as well, and it is an eye and skin irritant.

The findings have reduced its usage in hospitals, although the product still finds application in several settings, including:. Many people are wondering if the product is effective against germs and bacteria. The section below has answers to these queries that should help you to understand whether you need to use this solution or not.

The product is extremely helpful in eliminating germs, as it destroys germ cells.

After cleaning the surface, spray considerable amounts of the product on it and wait for a few minutes before wiping out the solution. This waiting time is enough to kill bacteria on the surface. Also, ensure you use protective wear during the process.

It is important since the product is highly irritating when in contact with the skin.

The best protective measure to take is to use gloves. The effectiveness of this product in killing viruses is almost similar to that of germs. An important thing about the item is that it kills multiple microorganisms, and it makes hydrogen peroxide as a disinfectant highly versatile. That said, the product kills viruses on hard and non-porous services. When you use it in the initial high concentration, wear gloves and other protective gear, as it is highly irritating to the skin and eyes.

This chemical compound is also known to cause mild discoloration. It is, therefore, important to test on the surface before applying the solution all over the place.

All in all, it is an ideal option compared to bleach.Hydrogen peroxide kills bacteria by oxidizing their cell walls, stealing electrons from them and disrupting their chemical structures.

Hydrogen peroxide is a compound with two hydrogen atoms and two oxygen atoms. It is very similar to water, but it has an extra oxygen atom that is shed readily to react with its environment, often in ways that are destructive to surrounding organisms.

The destructive oxygen in hydrogen peroxide is known as a free radical. The peroxide group, which is composed of two oxygen ions, reacts with bacterial cell walls and other cells' structures. Each oxygen atom has an unpaired electron, which is highly unstable and makes it extremely reactive. While hydrogen peroxide is a common disinfectant due to its bacteria-killing properties, it is dangerous to human cells as well as bacteria. It damages the surrounding tissue if it is left on a wound for too long.

At higher concentrations, it is corrosive. The body has some defenses against this activity, however, which produces the foaming often noted after hydrogen peroxide application. The human body has certain enzymes that help break down peroxides before they do too much damage, because such free radicals are formed naturally during aerobic respiration.

The focus on dietary antioxidants in recent years arises from metabolic free radicals damaging human cells in the same way that manufactured peroxide does. Home Science. What Are Some Examples of Solutions?
