Hand sanitizer is a popular tool for eliminating germs and killing viruses, including the common cold and coronavirus. It is most effective when it contains a high percentage of alcohol, specifically between 60% and 95% isopropanol or ethanol. Alcohol-based hand sanitizers are preferred over alcohol-free alternatives because they can alter the chemical structure of bacteria, while alcohol-free options may cause more harm than good. However, it's important to note that hand sanitizer is not effective against all germs, and hand-washing is recommended whenever possible. This article will explore the key indicators of an alcohol-based hand sanitizer and provide insights into its effectiveness and limitations.

What You'll Learn
Check the label for an expiration date or a minimum of 60% alcohol content
Hand sanitiser is a valuable tool for eliminating germs when you don't have access to soap and water. To be effective, it should contain at least 60% alcohol. Alcohol-based hand sanitisers use either ethanol or isopropanol, or sometimes a combination of the two. Health specialists recommend that hand sanitiser gels should contain above 70% ethanol to be effective.
Hand sanitiser will have an expiration date on the label, and it is required to be displayed by the FDA. If there is no expiration date, you can assume that the hand sanitiser will be good for around three years from the date of purchase. This is because, over time, the alcohol in the sanitiser will evaporate, reducing its potency and making it less effective at killing germs. If your hand sanitiser has expired, you should throw it away and replace it.
If you cannot see an expiration date and you don't know when you purchased the hand sanitiser, you can smell it to try to determine if it has gone bad. New hand sanitiser will have a strong alcohol odour, whereas old sanitiser will have a very faint smell as most of the alcohol will have evaporated.

Look for ethanol or isopropanol on the ingredients list
To identify if your hand sanitizer is alcohol-based, you should look for ethanol or isopropanol on the ingredients list. Ethanol is often listed on hand sanitizer labels as ethyl alcohol, while isopropanol may be listed as isopropyl alcohol or 2-propanol. According to the FDA, hand sanitizers should contain at least 60% ethanol to be effective against COVID-19.
Hand sanitizers with an alcohol content of 60-95% are most effective at killing germs. However, it's important to note that hand sanitizers are not effective against all types of germs, and handwashing with soap and water is always preferred when possible.
Over time, the alcohol in hand sanitizer will evaporate, reducing its potency and effectiveness. Therefore, hand sanitizers have an expiration date or a shelf life of around three years. If your hand sanitizer has expired, it should be replaced, as it will no longer be effective at killing germs.
It is important to supervise young children when they use hand sanitizer, as swallowing it can cause alcohol poisoning. Additionally, some hand sanitizers may contain methanol, a dangerous and toxic substance that can lead to serious side effects, including nausea, vomiting, headache, blurred vision, and even death. Always check the FDA's list of hand sanitizers with potential methanol contamination to ensure your product is safe.

Store it properly, in a cool, dry place
To ensure the longevity and effectiveness of your hand sanitizer, it is important to store it properly. Hand sanitizer should always be kept in a cool, dry place. This is because heat and sunlight can cause the alcohol in the sanitizer to evaporate over time, making it less effective or even ineffective at killing germs.
Ideally, you should store hand sanitizer in a cupboard or cabinet, away from direct sunlight and heat sources such as radiators or ovens. If you need to store it in a bathroom or kitchen, make sure it is kept in a cabinet or drawer and not left out on a counter or shelf where it could be exposed to heat and moisture.
Keeping hand sanitizer in a dry place is also important. Moisture can cause the sanitizer to become diluted and less potent, reducing its ability to kill germs. Avoid storing it in humid or damp environments, such as basements or garages, and do not place it near sinks or showers.
Additionally, it is worth noting that you should always keep hand sanitizer in its original container. These containers are designed to protect the sanitizer from light and air, which can also cause the alcohol to evaporate. Transferring the sanitizer to another container may compromise its effectiveness.
By following these storage guidelines, you can help maintain the quality and effectiveness of your hand sanitizer, ensuring that it retains its germ-killing properties for as long as possible. Proper storage is a simple but crucial step in making the most of this essential product.

Avoid products with methanol, especially if there are children around
While hand sanitizers are a valuable tool for eliminating germs, it is important to be cautious when using them, especially around children. Hand sanitizers are most effective when they are alcohol-based, with an alcohol content of at least 60%. However, it is crucial to avoid products that contain methanol, also known as methyl alcohol.
Methyl alcohol or methanol is a highly toxic form of alcohol that can have severe health consequences if ingested or absorbed through the skin. It is often included in hand sanitizers as a thinning agent or preservative, but its use is limited due to its higher toxicity compared to other alcohols. The ingestion of hand sanitizers containing methanol can be extremely dangerous and even lethal. This is a significant concern, especially for individuals struggling with alcohol addiction or young people experimenting with alcohol, as hand sanitizers may be easily accessible and tempting.
The toxic effects of methanol exposure can include serious health issues such as skin dryness, disruption of the skin's top layers, and in severe cases, even blindness or death. The FDA has issued warnings about methanol contamination in over 75 different hand sanitizers on the market, and it is known to the State of California to cause birth defects and reproductive harm. Therefore, it is crucial to avoid hand sanitizers containing methanol, especially if there are children in the household.
To ensure the safety of your family, always check the ingredient list on the hand sanitizer before purchasing it. Look for products that are certified methanol-free and contain safer alternatives such as isopropyl alcohol or ethanol. Additionally, keep hand sanitizers out of the reach of children, and supervise their use to prevent accidental ingestion or exposure.
Hand sanitizers are meant to protect us from germs and keep us healthy, but it is important to be vigilant about the products we choose, especially when it comes to methanol. By avoiding hand sanitizers with methanol and practicing proper hand hygiene, you can effectively reduce the risk of harmful exposure, especially for children.
