What is hand gel and how does it work?
Hand gel, commonly known as hydroalcoholic gel, is an effective disinfectant used to eliminate germs and bacteria from the skin. Its alcohol-based composition (usually ethanol or isopropanol) ensures fast, effective action, reducing the presence of micro-organisms on hands. As it evaporates, alcohol destroys the protein structure of pathogens, rendering them inactive. This product is particularly useful when access to soap and water is limited.
What are the main advantages of using hand gel?
There are several significant advantages to using hand gel:
- Immediate effectiveness: It works quickly to reduce germs on hands.
- Convenience: Easy to carry and use anywhere, ideal for hand hygiene on the move.
- Disease prevention: Helps prevent the spread of infectious diseases, especially during epidemics.
- Skin care: Many contain moisturizing agents to help prevent skin dryness.
How to choose the best hand gel?
To choose an effective hand gel, consider the following:
- Alcohol concentration: Opt for a gel containing at least 60% alcohol for maximum effectiveness.
- Moisturizing components: Look for gels enriched with aloe vera or glycerol to nourish the skin.
- Absence of strong fragrances: Fragrance-free formulas are recommended for sensitive skin and minimize the risk of allergies.
- Certifications: Give preference to products certified by health authorities, guaranteeing their efficacy and safety.
What are the guidelines for optimum use of hand gel?
To use hand gel effectively, follow these steps:
- Apply enough gel to cover all hand surfaces.
- Rub your hands together, including fingers, palms, backs of hands and wrists.
- Keep rubbing until the gel is completely absorbed and your hands are dry. This should take about 20 seconds.
Are there any risks associated with frequent use of hand gel?
Excessive use of hand gels can sometimes lead to undesirable effects, including:
- Skin dryness: Alcohol can dry out the skin, causing discomfort and irritation.
- Antibiotic resistance: Although rare, excessive use of certain types of antimicrobial gels can lead to bacterial resistance. To minimize these risks, alternate gel use with handwashing with soap and water, and use moisturizers regularly.
What types of hand gels are available on the market?
There are several types of hand gels to suit different needs and preferences:
- Antiseptic gels: These gels contain added antiseptics to enhance their disinfectant power, in addition to alcohol.
- Alcohol-based gels: These are the most common, effective against a wide range of micro-organisms.
- Alcohol-free gels: These use other antimicrobial agents, such as benzalkonium chloride, and are less drying for the skin.
- Organic and ecological gels: Made from natural ingredients and often alcohol-free, these gels are suitable for the eco-conscious.
Can I make my own hand gel at home?
It is possible to make your own hand gel. Here's a basic recipe:
- 90 ml 99% isopropyl alcohol
- 10 ml aloe vera gel to soften skin
- A few drops of essential oil (such as lavender or tea tree) to lightly scent the gel Mix the ingredients in a clean bottle and use the gel as directed for commercial products. However, it's important to note that homemade gels may not be as effective as the industrial versions.
Is hand gel as effective as handwashing with soap and water?
Hand gel is very effective at killing germs when soap and water aren't available, but handwashing with soap and water is generally more effective at eliminating germs and physical contaminants. Soap and water remove dirt, grease and certain microbes that hydroalcoholic gels may leave behind.
How can I integrate the use of hand gel into my daily hygiene routine?
Incorporating the use of hand gel into your daily routine is easy to do:
- After touching public surfaces: such as door handles, elevator buttons, etc.
- Before and after meals: to reduce the risk of transmitting bacteria.
- On public transport: where access to soap and water may be limited.
- After coughing, sneezing or blowing your nose: to maintain good hand hygiene in all circumstances.
Are there alternatives to hand gel when it's not available?
When hand gel is not available, other alternatives can be used:
- Disinfectant wipes: Although they don't completely replace hand washing, wipes can be an effective option for cleaning hands in the absence of gel.
- Disinfectant hand sprays: These alcohol-based products can also be used to disinfect hands quickly.
- Dry soaps: No-rinse soaps offer a practical alternative, especially when traveling or in situations where water is limited.
