Alcohol-based hand sanitizers have become increasingly popular in recent years, especially during the COVID-19 pandemic. While these sanitizers are effective in killing germs, concerns have been raised about the potential absorption of alcohol into the skin and its possible side effects. Some studies suggest that frequent use of alcohol-based sanitizers can lead to dry and damaged skin, and they may not be suitable for individuals with sensitive skin or children. Additionally, the presence of toxic chemicals like methanol and triclosan in some hand sanitizers has raised alarms, as these substances can be absorbed through the skin, causing health issues such as nausea, vomiting, and hormonal imbalances. However, it is important to note that according to a study published in the journal Alcohol and Alcoholism, significant absorption of ethanol from frequent use of hand sanitizers does not occur, and the World Health Organization (WHO) also confirms that blood alcohol levels do not rise significantly after using the appropriate amount of alcohol-based disinfectant.
| Characteristics | Values |
|---|---|
| Alcohol absorption into the skin | According to a study, there is no significant absorption of ethanol from frequent use of hand sanitizers. However, methanol, a toxic alcohol found in some hand sanitizers, can be absorbed through the skin and cause side effects such as nausea, vomiting, headache, hypothermia, and bluish skin colour. |
| Effect on skin | Alcoholic hand sanitizers can irritate and damage the skin, leading to dry and cracked skin. Alcohol-free hand sanitizers are gentler on the skin and contain ingredients like vitamin E and ceramides that restore the skin's natural barrier. |
| Effect on children | Hand sanitizers containing methanol can be dangerous for children as they may accidentally ingest them, leading to methanol poisoning. Alcohol-free hand sanitizers are generally considered safe for children. |
| Flammability | Alcohol-based hand sanitizers are flammable, posing a risk in certain work environments such as kitchens and healthcare settings. Alcohol-free hand sanitizers eliminate this risk. |
| Effectiveness against germs | Alcohol-based hand sanitizers are effective in killing most germs. However, they do not kill all types of germs and may not be suitable for frequent use throughout the day. Alcohol-free hand sanitizers, such as those containing benzalkonium chloride (BAC), can also be effective against a wide range of microorganisms, including germs, bacteria, and fungi. |

Alcohol-based hand sanitizers can irritate and damage skin
Alcohol-based hand sanitizers are designed to quickly reduce hand germs under certain conditions. However, excessive use of alcoholic hand sanitizers can irritate and damage the skin. The higher the alcohol concentration (ideally between 60 and 95 per cent), the better the hand sanitizer. However, high concentrations of alcohol can cause dryness and cracking of the skin, putting the skin at risk of bacterial infections.
Over time, using alcohol-based disinfectants can cause the skin on your hands to age faster than normal. The alcohol in the disinfectant solution makes the skin very inflamed, and dry and inflamed skin is prone to wrinkles and other blemishes. Alcoholic disinfectants do not kill all types of germs, and excessive use can also lead to alcohol poisoning, with side effects such as nausea, vomiting, headaches, hypothermia, and bluish skin colour.
According to the US Centers for Disease Control and Prevention (CDC), the best strategy to combat hand contamination is to wash hands regularly with soap and water. This method has been proven to reduce the number of microbes and chemicals on the hands without any side effects. However, soap and water are not always available, so hand sanitizers can be used to prevent the spread of pathogenic germs. Hand sanitizers are quick, easy, and portable.
Non-alcoholic hand sanitizers usually contain a combination of antibiotics called triclosan or yttrium chlorobarbane, and in some cases, benzalkonium chloride (BAC). These disinfectants also use emollients such as glycerin, which softens the skin after use. Nanosilver disinfectant is a type of non-alcoholic disinfectant that kills a wide range of microorganisms, germs, bacteria, and fungi. According to studies, these substances are more effective in killing 99.99 per cent of germs and viruses and are less harmful than alcohol.

Some hand sanitizers contain toxic methanol, which can be absorbed through skin
While hand sanitizers are useful when soap and water are not available, they can also be harmful. The US Centers for Disease Control and Prevention (CDC) maintains that washing hands regularly with soap and water is the best way to combat hand contamination. This method effectively reduces the amount of microbes and chemicals on the hands without any side effects.
Some hand sanitizers contain toxic methanol, also known as wood alcohol, which is dangerous when absorbed through the skin or swallowed. The FDA has warned consumers and healthcare professionals about hand sanitizers that contain methanol, as it can cause serious side effects such as nausea, vomiting, headache, blurred vision, permanent blindness, seizures, coma, permanent damage to the nervous system, and even death. Young children who accidentally swallow these products and adolescents and adults who drink these products as an alcohol substitute are most at risk of methanol poisoning.
It is important to note that most hand sanitizers found to contain methanol do not list it as an ingredient on the label, as it is not an acceptable ingredient. Therefore, consumers should regularly check the FDA's list of hand sanitizers with potential methanol contamination and immediately dispose of any products on the list.
In addition to methanol, other toxic chemicals in hand sanitizers include triclosan, a powerful antibacterial agent also used in pesticides, and fragrances. Triclosan is easily absorbed by the skin and can affect thyroid function and damage the liver and muscles. Fragrant alcoholic hand sanitizers are likely full of toxic chemicals, as manufacturers are not required to disclose the ingredients of these fragrances. These chemicals can disrupt the function of the endocrine glands and affect genital growth.
To conclude, while hand sanitizers can be useful in preventing the spread of pathogenic germs, it is important to be aware of their potential side effects and choose products that are safe for human use. Consumers should prioritize washing their hands with soap and water whenever possible and exercise caution when using hand sanitizers, especially those containing toxic ingredients like methanol.

Alcohol-free hand sanitizers are a safer, more skin-friendly option
Alcohol-based hand sanitizers are designed to quickly reduce hand germs, but they do not kill all types of germs. Alcohol-free hand sanitizers are a safer and more skin-friendly alternative. While alcoholic disinfectants are effective in certain conditions, their excessive use can irritate and damage the skin. Alcoholic hand sanitizers can also contain toxic chemicals, which are easily absorbed into the skin and can cause a range of issues, including nausea, vomiting, headaches, hypothermia, and bluish skin colour.
The use of alcohol-based hand sanitizers can be likened to the regular consumption of alcoholic beverages, which can lead to alcohol poisoning. This is especially dangerous for children, who may accidentally ingest the sanitizer. Manufacturers are not required to disclose the ingredients of fragrances used in scented sanitizers, and these often contain dozens of chemicals. These chemicals can include phthalates, which disrupt the function of endocrine glands and affect genital growth.
Triclosan, a common ingredient in non-alcoholic hand sanitizers, is also easily absorbed by the skin and can affect thyroid function, as well as cause liver and muscle damage. However, nanosilver disinfectants, another type of non-alcoholic option, have been found to be more effective than alcohol in killing 99.99% of germs and viruses, including E. coli and Salmonella. Benzalkonium chloride is another ingredient used in alcohol-free hand sanitizers, which has fast antiseptic and antimicrobial properties.
Overall, while hand sanitizers can be useful when soap and water are not available, alcohol-free options are a safer and more effective choice, causing fewer side effects and killing a wider range of germs.

Alcohol-based hand sanitizers are flammable and pose a risk if ingested
Alcohol-based hand sanitizers are a convenient way to ensure proper hand hygiene, which is critical for protecting ourselves and others from illnesses. They are designed to quickly reduce hand germs, and most of them contain 60-95% alcohol to kill bacteria and viruses. However, it is important to note that these sanitizers have certain drawbacks and risks associated with them.
One of the primary concerns with alcohol-based hand sanitizers is their flammability. The high alcohol content in these products makes them highly flammable, which poses a safety risk in certain environments. For example, they may not be suitable for use in kitchens, manufacturing facilities, or healthcare settings, where fire safety is a critical concern. The risk of flammability may also be relevant during air travel or other situations where an open flame or spark could be present.
Another significant risk associated with alcohol-based hand sanitizers is the danger of ingestion. Ingesting these products can lead to alcohol poisoning, especially in children who may accidentally drink them due to their easy accessibility. Methanol, a type of toxic alcohol found in some hand sanitizers, can cause severe side effects such as nausea, vomiting, headaches, hypothermia, and even bluish skin colour if absorbed through the skin or ingested in large amounts. In more serious cases, methanol ingestion can lead to blindness, seizures, nervous system damage, and can even be fatal.
Furthermore, frequent use of alcohol-based hand sanitizers can irritate and damage the skin, causing dryness and cracking. This is especially pertinent for individuals with sensitive skin or those who use sanitizers frequently throughout the day. Additionally, there are concerns about the potential impact of hand sanitizers on hormonal balance. Some of the chemicals used in fragrant hand sanitizers, such as phthalates, can disrupt the function of endocrine glands, ultimately affecting genital growth and potentially leading to infections and diseases.
While alcohol-based hand sanitizers can be effective in killing germs, it is crucial to be aware of their limitations and potential risks. In situations where flammability or ingestion may be a concern, or for individuals with sensitive skin, alcohol-free hand sanitizers can be a safer and more suitable alternative. These non-alcoholic options, such as those containing benzalkonium chloride or nanosilver, provide effective germ protection without the harsh effects of alcohol and are generally gentler on the skin.

Hand sanitizers may contain triclosan, which is easily absorbed and can affect thyroid function
Hand sanitizers have become increasingly common, especially in the wake of the COVID-19 pandemic. While hand sanitizers are an effective way to maintain hand hygiene, some hand sanitizers contain triclosan, which is easily absorbed through the skin and can affect thyroid function.
Triclosan is a chemical with broad-spectrum anti-microbial activity against most gram-negative and gram-positive bacteria. It is commonly used in personal care products, household products, and even some medical devices. It is also often found in antibacterial soap and toothpaste. The concern with triclosan is that it is an endocrine disruptor, which means it can interfere with the body's hormone activity. This can lead to hormonal imbalances and affect thyroid function, particularly in those with an existing thyroid or autoimmune thyroid condition. Research has shown that triclosan directly affects thyroid hormone levels, with studies indicating that triclosan suppressed serum thyroid hormone levels.
The skin is a large absorptive organ, and substances applied to it can enter the body and affect various systems. In the case of triclosan, it has been detected in breast milk, urine, and plasma, with levels in the blood correlating with consumer use patterns. This is particularly concerning for pregnant women, as triclosan can cross the placenta and enter the breast milk, potentially impacting the developing fetus.
While the FDA has banned triclosan from antibacterial soaps and body washes, it is still allowed in other products like hand sanitizers, wipes, deodorants, hairsprays, and toothpastes. The FDA has, however, required manufacturers of hand sanitizers to provide data proving the safety and effectiveness of their active ingredients.
It is worth noting that the effects of long-term exposure to triclosan are still being studied, and some studies have shown conflicting results. For example, while triclosan has been linked to increased cancer progression, it has also been suggested as a potential treatment for certain cancers. Nonetheless, due to the potential risks associated with triclosan, it is advisable to opt for natural hand sanitizers or those that do not contain triclosan.
