In today’s world, maintaining good hygiene is more critical than ever. Amid global health concerns and daily encounters with germs, hand sanitizers have emerged as a cornerstone of personal hygiene. Their convenience and effectiveness make them an indispensable tool in our defense against harmful pathogens. This blog will delve into the various aspects of hand sanitizers, including their history, types, effectiveness, usage tips, and role in public health.

The Evolution of Hand Sanitizers

The journey of hand sanitizers from niche products to household essentials is fascinating. Although the concept of using alcohol to cleanse hands dates back to the late 19th century, it wasn't until the 1960s that hand sanitizers began to resemble the products we use today.

The modern hand sanitizer was invented in 1966 by Lupe Hernandez, a nursing student from Bakersfield, California, who combined alcohol with a gel to create a portable cleaning solution. This innovation lay dormant until the 1980s when it was reintroduced by companies like Purell, making hand sanitizers widely available. The 2009 H1N1 flu pandemic and the recent COVID-19 pandemic have further accelerated their adoption globally.

Types of Hand Sanitizers

Hand sanitizers come in various formulations, each suited for different needs and preferences. Understanding the differences can help in choosing the most effective product for specific circumstances.

Alcohol-Based Sanitizers

Composition: These typically contain 60-95% alcohol (ethanol, isopropanol, or n-propanol).

Effectiveness: Alcohol-based sanitizers are highly effective against a broad spectrum of germs, including bacteria, viruses, and fungi. They work by denaturing proteins and disrupting the lipid membranes of microorganisms.

Usage: Ideal for general use, especially in healthcare settings, public spaces, and during travel.

Non-Alcohol-Based Sanitizers

Composition: These use disinfectants like benzalkonium chloride instead of alcohol.

Effectiveness: They are less effective against viruses compared to their alcohol-based counterparts but can still kill bacteria and some viruses.

Usage: Suitable for individuals sensitive to alcohol or for situations where alcohol use is restricted.

Natural and Organic Sanitizers

Composition: These often include essential oils, plant-based alcohols, and other natural ingredients.

Effectiveness: While appealing for their who prioritize natural products and seek to minimize exposure to synthetic chemicals.

How Hand Sanitizers Work

The effectiveness of hand sanitizers lies in their ability to disrupt the structure of germs. Here's a deeper look into how they work:

Alcohol-Based Sanitizers: The primary germ-killing action comes from alcohol. Alcohol disrupts the cell membranes of bacteria and viruses, denatures their proteins, and dissolves lipids, leading to cell death. For maximum efficacy, a hand sanitizer should contain at least 60% alcohol. Higher concentrations can further enhance germicidal activity but may also dry out the skin.

Non-Alcohol-Based Sanitizers: These rely on chemical agents like benzalkonium chloride to destroy microorganisms by breaking down cell membranes and denaturing proteins. While they can be effective, their germ-killing spectrum is narrower than alcohol-based products, and they might require longer contact time to achieve similar results.

Natural and Organic Sanitizers: These typically include antimicrobial essential oils like tea tree oil or thyme oil. While they can provide a degree of germicidal activity, their effectiveness is generally less compared to conventional sanitizers. They are best used as supplements rather than primary means of sanitization.

Correct Usage of Hand Sanitizers

To maximize the effectiveness of hand sanitizers, proper usage is crucial. Here are some key steps:

Application: Apply a generous amount of sanitizer (about the size of a dime or quarter) to the palm of one hand.

Spreading: Rub your hands together, covering all surfaces, including the backs of your hands, between your fingers, and under your nails. Continue rubbing for at least 20-30 seconds until your hands are dry.

Reapplication: Use hand sanitizer when soap and water are not available, especially after touching high-contact surfaces, coughing, or sneezing.

Avoidance of Certain Conditions: Hand sanitizers are less effective when hands are visibly dirty or greasy. In such cases, washing with soap and water is recommended.

Benefits of Hand Sanitizers

Hand sanitizers offer numerous benefits, making them an essential part of personal hygiene and public health:

Convenience: Portable and easy to use, hand sanitizers provide quick disinfection on the go, making them ideal for use in public spaces, during travel, and when soap and water are not available.

Effective Germ Control: High-alcohol formulations can kill a broad spectrum of pathogens, reducing the risk of infections.

Complement to Handwashing: While not a substitute for handwashing, hand sanitizers are a valuable adjunct, especially in situations where soap and water are unavailable.

Reduced Spread of Illness: Regular use of hand sanitizers can significantly reduce the transmission of infectious diseases, benefiting both individuals and communities.

Limitations of Hand Sanitizers

Despite their many benefits, hand sanitizers have limitations:

Reduced Efficacy on Soiled Hands: Hand sanitizers are less effective on visibly dirty or greasy hands. Soap and water remain the preferred method for thorough cleaning.

Skin Irritation: Frequent use of alcohol-based sanitizers can cause dryness and irritation. Using moisturizers can help mitigate these effects.

Limited Range: Non-alcohol-based sanitizers may not be effective against all types of germs, particularly certain viruses.

Potential for Misuse: Over-reliance on hand sanitizers can lead to neglect of handwashing, which is crucial for removing dirt and certain pathogens.

The Role of Hand Sanitizers in Public Health

Hand sanitizers play a vital role in controlling the spread of infectious diseases, especially in public health scenarios:

Outbreaks and Pandemics: During outbreaks, such as the H1N1 flu or COVID-19, hand sanitizers have been crucial in curbing the transmission of viruses in settings where handwashing facilities are limited.

Healthcare Settings: In hospitals and clinics, hand sanitizers are essential for maintaining hygiene standards, preventing healthcare-associated infections, and ensuring the safety of both patients and healthcare workers.

Educational Institutions: Schools and universities use hand sanitizers to reduce the spread of germs among students and staff, promoting a healthier learning environment.

Public and Community Spaces: Hand sanitizers are commonly placed in high-traffic areas like malls, airports, and public transportation hubs to encourage good hygiene practices and reduce the risk of infection.

Choosing the Right Hand Sanitizer

Selecting an appropriate hand sanitizer involves considering several factors:

Alcohol Content: For effective germ control, choose a sanitizer with at least 60% alcohol content.

Formulation: Gel formulations are easy to apply and control, while sprays can cover larger surfaces quickly. Wipes offer convenience for on-the-go cleaning but may not always be as effective as liquid forms.

Ingredients: For sensitive skin, look for sanitizers with added moisturizers or natural ingredients to minimize irritation.

Certifications: Ensure the sanitizer is approved by relevant health authorities, such as the FDA or WHO, to guarantee its efficacy and safety.

Conclusion

Hand sanitizers have become an integral part of our daily lives, offering a convenient and effective means to maintain hygiene and prevent the spread of germs. Their role in public health, particularly during outbreaks and in healthcare settings, underscores their importance. By understanding their types, proper usage, and benefits, we can make informed choices and use hand sanitizers effectively as a part of our overall hygiene practices.

Coronavirus spreads from person to person via droplets of infected fluid. These are passed on through direct hand to hand contact or from contaminated surfaces, or when someone standing close to an infected person breathes in droplets that have been sneezed or coughed into the air. 

According to the experts, spending time focusing on hand hygiene can help you reduce the risk of picking up coronavirus, as well as other infectious diseases. The way you wash your hands is important. So have a quick look at the things that matter.

1. Don't be quickA quick splash isn't enough. For clean and germ-free hands you'll need to wash your hands under clean running water, lasting 20 seconds, with lots of rubbing together of the hands. Children can be encouraged to sing their favorite song twice to make sure they wash their hands for long enough.

2. Soap upIf you're at a tap and there's some soap nearby, you must use it. Any germs on your hands will be attached to the layer of oils, acidic fats, and cellular debris on the surface of the skin. Soap dissolves this layer and so does a better job of removing the germs than merely rubbing your hands under water alone.

3. Liquid versus bar soapThough liquid soap is less likely to be contaminated than bar soap, this is more of an issue in public places than at home.

4. Antibacterial isn't any betterIt may be tempting to use antibacterial soaps to be sure you get rid of all the germs, but there's no evidence these products work any better than regular soap and water. Instead, there are fears these products may cause harm by encouraging bacteria to become resistant to their active ingredients.

5. Running water is bestTry to wash your hands in running water if possible, as clean hands are likely to become contaminated again if you wash them in a bowl of water. Keep waterless hand sanitizer handy in case there is no running water nearby.

6. Water temperatureHot water may kill disease-causing germs, but it could leave you with significant burns. Also soap lathers better in warm water, which is also less likely to strip away natural oils from your skin than either hot or cold water.

7. Rinse wellOnce the soap and the friction have lifted the germs and dirt from your hands, you want to rinse them under the clean running water.When there's no water, an alcohol-based hand sanitizer that contains at least 60 percent alcohol is your best bet.
