Ethyl alcohol is safer for skin than isopropyl alcohol
Hand sanitizers are a great way to keep our hands free from germs when we don't have access to soap and water. The Centers for Disease Control and Prevention (CDC) recommends using hand sanitizers with at least 60% alcohol content to effectively kill bacteria, viruses, and other harmful germs. While both ethyl alcohol and isopropyl alcohol are commonly used in hand sanitizers, ethyl alcohol is safer for the skin.
Ethyl alcohol, also known as ethanol, is the most well-known type of alcohol and is commonly consumed in alcoholic beverages. It is also used in various products that come into direct contact with the skin, such as disinfectants, mouthwashes, and hair sprays. Studies have shown that ethyl alcohol does not cause skin damage, even when used frequently. In fact, a 2017 study found that isopropyl alcohol and n-propanol caused significant damage to skin condition and function, while ethyl alcohol did not exhibit the same effects.
Isopropyl alcohol, often referred to as "rubbing alcohol," has a similar molecular structure to ethyl alcohol but contains one more carbon and two additional hydrogen molecules. It is widely used as an antiseptic and disinfectant and can be found in lotions, cosmetics, and face washes. While both types of alcohol can effectively kill germs, isopropyl alcohol is not as effective against non-enveloped viruses, such as hepatitis, rotavirus, and adenovirus.
When choosing a hand sanitizer, it is important to prioritize skin safety. The CDC recommends selecting a product with at least 60% ethyl or isopropyl alcohol content. However, it is worth noting that hand sanitizers made outside the United States may contain methanol, a highly toxic form of alcohol. Always read the labels, supervise children under six when using hand sanitizers, and seek immediate medical attention if accidental ingestion occurs.
In summary, while both ethyl and isopropyl alcohol are effective disinfectants, ethyl alcohol is the preferred choice for hand sanitizers due to its lower skin damage potential. Its effectiveness against a broader range of viruses and its safer ingestion profile make it a safer option for hand hygiene products.

Ethyl alcohol is made from renewable sources, unlike isopropyl alcohol
Ethyl alcohol, also known as ethanol, is commonly used as a disinfectant and antiseptic. It is effective at killing a large range of viruses and bacteria and is often found in hand sanitizers. Ethyl alcohol is naturally produced by yeasts during sugar fermentation and is therefore a renewable resource. It is also used in alcoholic beverages, fuel, and as a solvent.
On the other hand, isopropyl alcohol is a secondary alcohol with a different chemical structure and is not produced by a renewable process. It is commonly referred to as "rubbing alcohol" and is used in healthcare settings as a disinfectant and antiseptic. Isopropyl alcohol is also found in lotions, cosmetics, and household cleaning products.
Both types of alcohol are effective at killing germs, but ethyl alcohol is generally considered safer for the skin, as some studies have found that isopropyl alcohol can cause significant damage to skin condition and function. It is important to note that both types of alcohol are toxic if ingested, but isopropyl alcohol is more poisonous when consumed and can lead to serious health complications or even death.
When choosing a hand sanitizer, it is recommended to select one that contains at least 60% ethyl or isopropyl alcohol, as this concentration is effective at killing germs. However, it is always preferable to wash hands with soap and water whenever possible, as handwashing reduces all types of germs and chemicals on the hands.
In summary, ethyl alcohol is a renewable resource that is commonly used in hand sanitizers, while isopropyl alcohol is not derived from renewable sources. Both types of alcohol have disinfectant properties, but ethyl alcohol is generally considered safer for the skin and consumption within regulated limits.

Hand sanitizers are flammable and should be disposed of safely
Hand sanitizers are a great way to keep your hands clean and free of germs when you're on the go. However, it's important to remember that most hand sanitizers are flammable due to their alcohol content and should be disposed of safely.
The Centers for Disease Control and Prevention (CDC) recommends using hand sanitizers with at least 60% alcohol, which is effective at killing bacteria, viruses, and other harmful microbes. This high alcohol content, however, also makes hand sanitizers highly flammable. In fact, the FDA requires alcohol-based hand sanitizers to be labelled as flammable.
When disposing of hand sanitizers, it is crucial to never pour them down the drain. Alcohol-based hand sanitizers are considered hazardous waste, and their ignitable nature poses a serious risk when disposed of improperly. Improper disposal can lead to dangerous consequences, such as fires or explosions.
So, what is the best way to dispose of hand sanitizers safely? The US Environmental Protection Agency (EPA) provides guidelines for businesses and institutions to manage and dispose of excess hand sanitizer in accordance with regulations. For example, recycling excess hand sanitizer is encouraged, provided it complies with the legitimacy criteria outlined by the EPA. Additionally, industrial ethyl alcohol reclaimers with the appropriate permits can recover the alcohol from hand sanitizers for use in other products, such as lab chemicals or cleaning agents.
It is important to follow these guidelines and properly manage and dispose of hand sanitizers to ensure the safety of your household and the environment.

Hand sanitizers may contain methanol, which is toxic
The use of hand sanitizers has become increasingly common, especially in recent years. While they can be effective at killing bacteria, viruses, and other disease-causing microbes, it is important to be aware of the potential risks associated with their use. Hand sanitizers may contain different types of alcohols, including ethyl alcohol (ethanol) and isopropyl alcohol, which are recognized by the FDA as safe for use in hand sanitizers. Both types of alcohol are effective disinfectants and antiseptics, but isopropyl alcohol is derived from non-renewable sources and is considered more toxic when ingested.
However, a significant concern arises with the potential presence of methanol in hand sanitizers. Methanol, also known as wood alcohol, is a highly toxic substance that can be found in hand sanitizers, particularly those produced outside the United States. Ingesting even small amounts of methanol can lead to serious health consequences, including methanol poisoning, permanent vision loss, and even death. The Centers for Disease Control and Prevention (CDC) reported cases of methanol poisoning associated with drinking alcohol-based hand sanitizers, emphasizing the dangers of accidental consumption.
The inclusion of methanol in hand sanitizers poses a significant risk, especially for children who may accidentally ingest it. While the FDA regulates the use of ethyl alcohol and isopropyl alcohol in hand sanitizers, the presence of other toxic substances, such as methanol, underscores the importance of vigilant supervision and proper storage of these products. It is crucial for consumers to carefully read the labels of hand sanitizers and ensure they are purchasing products from reputable sources that adhere to safety standards.
To minimize the risk of accidental ingestion or exposure to toxic substances, it is recommended to prioritize handwashing with soap and water whenever possible. While hand sanitizers can be a convenient alternative when soap and water are unavailable, they should not replace proper handwashing as the primary means of maintaining hand hygiene. By following these precautions and staying informed about the ingredients in hand sanitizers, individuals can make safer choices for themselves and their families.
