The COVID-19 pandemic has brought hand hygiene to the forefront of our daily lives. With the constant reminders to wash our hands frequently, many of us have turned to hand sanitizers as a convenient alternative to soap and water. But is it safe to use hand sanitizers instead of soap and water? In this article, we’ll delve into the world of hand sanitizers, exploring their benefits, risks, and limitations.
What are Hand Sanitizers, and How Do They Work?
Hand sanitizers are liquid or gel-like substances that contain active ingredients, usually ethanol or isopropanol, which kill or inactivate microorganisms on the skin. These products are designed to be used when soap and water are not available, providing a quick and easy way to reduce the number of germs on our hands.
The active ingredients in hand sanitizers work by:
- Disrupting the cell membranes of microorganisms, ultimately leading to their death
- Denaturing proteins, making it difficult for microorganisms to function and multiply
- Interfering with the metabolism of microorganisms, preventing them from producing energy
The Benefits of Hand Sanitizers
Hand sanitizers have several benefits that make them a popular choice for hand hygiene:
- Convenience: Hand sanitizers are portable and easy to use, making them perfect for on-the-go hand hygiene.
- Time-saving: Hand sanitizers are quick to apply and dry, saving time compared to washing hands with soap and water.
- Accessibility: Hand sanitizers can be used when soap and water are not available, making them a great option for people who work outdoors or in areas with limited access to clean water.
The Risks of Hand Sanitizers
While hand sanitizers are generally safe to use, there are some risks and limitations to consider:
- Skin irritation: Some people may experience skin irritation, such as redness, itching, or dryness, after using hand sanitizers.
- Allergic reactions: Rarely, people may be allergic to the active ingredients in hand sanitizers, which can cause more severe reactions, such as hives or difficulty breathing.
- Ineffective against certain germs: Hand sanitizers may not be effective against certain types of germs, such as norovirus, rotavirus, and Clostridioides difficile (C. diff).
- Overuse: Using hand sanitizers too frequently can lead to dry, cracked skin, which can increase the risk of infection.

How to Use Hand Sanitizers Effectively
To get the most out of hand sanitizers, follow these tips:
- Use enough product: Use enough hand sanitizer to cover your hands completely, making sure to get the backs of your hands, between your fingers, and under your nails.
- Rub it in: Rub the hand sanitizer into your skin until it’s dry, making sure to cover all surfaces.
- Avoid touching your face: Try to avoid touching your face, especially your eyes, nose, and mouth, after using hand sanitizer.
- Don’t use hand sanitizer on dirty hands: Hand sanitizers are not effective on dirty or greasy hands. Wash your hands with soap and water instead.
The Limitations of Hand Sanitizers
While hand sanitizers are a great tool for hand hygiene, they have some limitations:
- They may not be as effective as soap and water: Hand sanitizers may not be as effective as soap and water in removing dirt, grime, and germs from the skin.

- Antibacterial wipes: Antibacterial wipes can be used to clean surfaces and hands, providing a convenient alternative to hand sanitizers.

What are the benefits of using hand sanitizers?
Hand sanitizers are a convenient and effective way to reduce the spread of germs and illnesses. They are especially useful when soap and water are not available, such as when traveling, at work, or in public places. Hand sanitizers can help kill a wide range of microorganisms, including bacteria, viruses, and fungi, which can cause a variety of illnesses.
The benefits of using hand sanitizers extend beyond personal health. They can also help prevent the spread of illnesses in communities, schools, and workplaces, which can lead to reduced absenteeism and increased productivity. Additionally, hand sanitizers can be a useful tool in areas where access to clean water and soap is limited.
What are the risks associated with using hand sanitizers?
While hand sanitizers can be an effective way to reduce the spread of germs, there are also some risks associated with their use. One of the main risks is the potential for skin irritation, such as dryness, redness, and itching. This is especially true for people with sensitive skin or allergies. Additionally, some hand sanitizers may contain harsh chemicals, such as triclosan, which has been linked to hormone disruption and other health problems.
Another risk associated with hand sanitizers is the potential for overuse. While hand sanitizers can be effective against a wide range of microorganisms, they are not a substitute for washing hands with soap and water. Overusing hand sanitizers can lead to a false sense of security, causing people to neglect proper handwashing techniques. This can lead to the spread of illnesses and the development of antibiotic-resistant bacteria.
How do I choose a safe and effective hand sanitizer?
When choosing a hand sanitizer, it’s essential to read the label carefully. Look for a hand sanitizer that contains at least 60% ethanol or 70% isopropanol, which are the active ingredients that kill germs. Avoid hand sanitizers that contain harsh chemicals, such as triclosan, and opt for fragrance-free or hypoallergenic options if you have sensitive skin.
It’s also essential to check the expiration date of the hand sanitizer and follow the instructions for use carefully. Make sure to apply the hand sanitizer to all surfaces of your hands, including the backs of your hands, wrists, and between your fingers. Rub your hands together until the hand sanitizer is fully absorbed, and avoid wiping your hands on your clothes or other surfaces.
Can I make my own hand sanitizer at home?
While it’s possible to make your own hand sanitizer at home, it’s not recommended. Hand sanitizers require a specific concentration of active ingredients, such as ethanol or isopropanol, to be effective against germs. If you don’t get the concentration right, the hand sanitizer may not be effective, or it may be too harsh on your skin.
Additionally, making your own hand sanitizer at home can be risky if you don’t follow proper safety protocols. For example, if you’re using ethanol or isopropanol, you’ll need to handle these chemicals carefully to avoid skin irritation or other accidents. It’s generally safer and more effective to use a commercially available hand sanitizer that has been tested and proven to be safe and effective.
Are hand sanitizers safe for children?
Hand sanitizers can be safe for children if used properly. However, it’s essential to choose a hand sanitizer that is specifically designed for children and to follow the instructions for use carefully. Children under the age of 6 should be supervised when using hand sanitizers, and children under the age of 2 should not use hand sanitizers at all.
When choosing a hand sanitizer for children, look for a product that is fragrance-free and hypoallergenic to reduce the risk of skin irritation. Also, make sure to teach children how to use hand sanitizers properly, including applying the product to all surfaces of their hands and rubbing their hands together until the product is fully absorbed.
Can hand sanitizers replace washing hands with soap and water?
No, hand sanitizers should not replace washing hands with soap and water. While hand sanitizers can be effective against a wide range of microorganisms, they are not a substitute for proper handwashing techniques. Hand sanitizers may not be effective against all types of germs, such as norovirus, rotavirus, and Clostridioides difficile (C. diff), which can cause a range of illnesses.
Additionally, hand sanitizers may not remove dirt, grime, or other substances from your hands, which can harbor germs. Washing your hands with soap and water is still the best way to remove germs and prevent the spread of illnesses. Hand sanitizers should be used in addition to, not instead of, washing your hands with soap and water.
How often should I use hand sanitizer?
You should use hand sanitizer when soap and water are not available, such as when traveling, at work, or in public places. You should also use hand sanitizer after using the bathroom, before eating, and after blowing your nose, coughing or sneezing. Additionally, you should use hand sanitizer after touching animals, their food or waste, and after being in contact with someone who is sick.
However, you should not overuse hand sanitizer. Washing your hands with soap and water is still the best way to remove germs and prevent the spread of illnesses. If you’re in a situation where you need to wash your hands frequently, such as in a healthcare setting, you should use soap and water instead of hand sanitizer.
