How Effective are Different Types of Hand Sanitisers?

In recent years, the importance of proper hand hygiene has become increasingly emphasised, making hand sanitisers an essential part of our daily routines—particularly in places where soap and water are not readily available. With numerous products on the market, understanding the varying effectiveness of different hand sanitisers can be crucial in making informed choices. In the article below, we will explore what makes hand sanitisers effective, helping you to find the best option for maintaining proper hand hygiene in your work and daily life.

 

Alcohol-Based Hand Sanitisers

Alcohol-based hand sanitisers are the most commonly recommended by health authorities, including the World Health Organisation. Typically containing between 60% and 95% alcohol, these sanitisers have been proven highly effective at killing germs by denaturing proteins and neutralising harmful pathogens such as bacteria, viruses, and fungi. They act quickly, do not require rinsing, and offer a convenient solution for maintaining hygiene on the go.

 

Alcohol-Free Hand Sanitisers

Alcohol-free hand sanitisers typically use benzalkonium chloride or triclosan as active ingredients. They are beneficial in settings where alcohol sensitivity is a concern, also providing a good option for individuals who avoid alcohol for religious reasons. Although generally considered less effective against certain germs when compared to alcohol-based sanitisers, alcohol-free options tend to be more moisturising and gentler on the skin.

 

Effectiveness Against Viruses

Alcohol-based sanitisers are particularly effective against enveloped viruses, such as the common cold, flu, and even the coronavirus. They disrupt the virus’s outer coat, rendering it inactive. However, they are less effective against non-enveloped viruses like norovirus.

 

Application and Limitations

The effectiveness of hand sanitisers depends largely on their proper use. It’s important to use a sufficient amount and to cover all parts of the hands, rubbing them together until they feel dry. Sanitisers should not be used on soiled or greasy hands; in such cases, washing with soap and water is preferable.

 

Considerations for Sensitive Skin

For those with sensitive skin, it’s advisable to look for sanitisers with added moisturisers to help mitigate dryness and irritation. Unscented and alcohol-free options are typically preferable to avoid skin irritation, dermatitis, and any other potential skin reactions.

 

In conclusion, while alcohol-based hand sanitisers offer the best protection against a wide range of pathogens, choosing the right type for you will depend on your individual needs and specific situations. When possible, it’s recommended that your chosen hand sanitiser meets the recommended alcohol concentration to maximise its germ-killing effectiveness.
