Isopropyl alcohol and hydrogen peroxide don't react without a catalyst
Isopropyl alcohol and hydrogen peroxide are both simple and inexpensive liquids commonly used as antiseptics or disinfectants. They are both effective at killing bacteria, viruses, and fungi. However, they serve different purposes and are used under different conditions. Isopropyl alcohol is typically used to clean fresh wounds before dressing, while hydrogen peroxide is more suitable for cleaning deeper wounds with debris that are difficult to manually scrub.
Although isopropyl alcohol and hydrogen peroxide can be used together topically, they do not react without a catalyst. To minimize the possibility of a reaction, it is recommended to mix them just before use. Additionally, it is important to note that mixing these two substances does not create a more effective disinfectant. Their individual uses should be considered, and they should not be combined in an attempt to create a stronger antiseptic.
The reaction between isopropyl alcohol and hydrogen peroxide can be unsafe under certain conditions. For example, if the mixture comes into contact with an open flame, it will catch on fire very quickly. It is crucial to exercise caution and avoid any potential ignition sources when working with this mixture.
While some people have shared their positive experiences using isopropyl alcohol and hydrogen peroxide to clean wounds, it is important to consult a medical professional before applying any substance to an open wound. The wound cleaning process should also include regular changing of bandages and allowing the wound to breathe. Prolonged use of either substance on the same bandage can lead to dryness and cracking of the scab, making the wound vulnerable to infection.
In summary, isopropyl alcohol and hydrogen peroxide are useful individual substances with distinct advantages in various applications. When used appropriately, they can be effective disinfectants and antiseptics. However, they do not react without a catalyst, and combining them does not enhance their disinfectant properties. It is important to use them safely and according to recommendations to avoid potential hazards.

Hydrogen peroxide is an antiseptic that kills viruses, bacteria and fungi
Hydrogen peroxide is a simple and inexpensive liquid that has been used as an antiseptic since the mid-1800s. It is a versatile chemical that can be used for cleaning, disinfecting, and stain removal. It is also used in the food industry for processing and bleaching certain foods.
Hydrogen peroxide is an effective antiseptic that kills viruses, bacteria, and fungi. It is often used to disinfect household surfaces and can be used as a mouth rinse to help remove phlegm, mucus, and other unpleasant mouth secretions. It is also useful for cleaning wounds, although there is some debate about its effectiveness in this regard. Some experts say that hydrogen peroxide should no longer be used to clean wounds as it can irritate the skin and may prevent proper healing. However, others argue that it can be effective in wound healing when used at the right concentration.
When used for wound cleaning, hydrogen peroxide kills pathogens through oxidation burst and local oxygen production. It is also a signalling molecule that influences biological behaviour through multiple mechanisms, including alterations of membrane potential and the generation of new molecules. The concentration of hydrogen peroxide in wound tissue influences the outcome of the healing process to a certain extent.
In addition to its antiseptic properties, hydrogen peroxide can also be used as an oral debriding agent and as a gargle and rinse. It is available in different concentrations, with the 3% solution being commonly used for topical applications and first aid wound care. It is important to use hydrogen peroxide with caution, as it can be toxic if inhaled or if it comes into contact with the skin. It should be stored in a locked cabinet out of the reach of children and pets.

Rubbing alcohol is an effective disinfectant, killing bacteria like E. coli in 10 seconds
Rubbing alcohol, also known as isopropyl alcohol or isopropanol, is an effective disinfectant that can kill bacteria like E. coli in as little as 10 seconds. It is often used for disinfecting surfaces, such as countertops, thermometers, door handles, phones, keyboards, and other frequently touched objects. It is also useful for sanitizing shoes and deodorizing armpits, though it should not be applied to freshly shaved skin as it can sting. Rubbing alcohol is also effective against other bacteria, such as Staphylococcus aureus, and viruses, including the one that causes COVID-19.
The effectiveness of rubbing alcohol as a disinfectant is attributed to its high alcohol content, typically between 60% and 90% for isopropyl alcohol. Ethanol, chemically the same as drinking alcohol, is another type of alcohol used in disinfectants and is generally more potent than isopropyl alcohol, depending on the type of microbe being targeted.
While rubbing alcohol is an effective disinfectant, it has some drawbacks. It can be harsh on the skin, causing dryness, and should not be used on open wounds or cuts as it can damage healthy tissue. Additionally, it can be harsh on certain surfaces, potentially damaging porous materials like wood or granite and removing protective coatings.
In comparison to hydrogen peroxide, another commonly used disinfectant, rubbing alcohol works faster. Hydrogen peroxide can take up to five minutes to kill germs and is effective against various bacteria and viruses, including the COVID-19 virus. It has been found to be more effective than rubbing alcohol against certain infections, such as Clostridium difficile (C-Diff). However, hydrogen peroxide can also be harsh on the skin and should not be used continuously on wounds as it can cause dryness and cracking, leading to a higher risk of infection.
While there have been discussions about mixing isopropyl alcohol and hydrogen peroxide for topical use, it is generally not recommended as it does not create a more effective disinfectant. Both have their unique uses, and mixing them may not provide the desired benefits of either solution.

Ethanol can be oxidised by hydrogen peroxide to form acetic acid
Ethanol (CH3CH2OH) is a primary alcohol commonly found in alcoholic drinks. It can be oxidised to form ethanoic acid, also known as acetic acid (CH3COOH). This reaction typically occurs in two stages, and hydrogen peroxide can be used as an oxidising agent.
Firstly, the ethanol is oxidised to acetaldehyde (CH3CHO), which can be identified by its sweet smell. This reaction also produces water. Secondly, the acetaldehyde is further oxidised to form ethanoic acid, which has a sharper, more vinegary smell. This solution is then distilled to remove any remaining water, resulting in an aqueous solution of ethanoic acid.
It is important to note that hydrogen peroxide is extremely reactive and unstable. Higher concentrations are more reactive, and it is essential to handle it with caution. In one instance, a mixture of hydrogen peroxide and ethanol exploded during a test in Kummersdorf, Germany, in 1934. Therefore, attempting to oxidise ethanol with hydrogen peroxide should only be done by trained and well-equipped chemists.
Additionally, ethanol can be converted into ethanoic acid through other methods, such as the metabolism of ethanol in the liver by an enzyme called alcohol dehydrogenase. This process also produces acetaldehyde as an intermediate product, which is further metabolised into ethanoic acid.
Ethanoic acid has a wide range of applications, including household cleaning, culinary, medical, and industrial uses. It is the active ingredient in vinegar and is often used as a preservative due to its ability to inhibit bacterial growth.
