Keeping your hands clean is essential for preventing the spread of germs. Many hand sanitizers contain at least 60 alcohol, which is considered effective in killing certain types of bacteria and viruses. However, handwashing with soap and water remains the best method when available.
Why 70% alcohol is effective
A hand sanitizer with 70% alcohol is preferred because it effectively kills microbes while retaining some water content to slow evaporation. Using a higher volume of alcohol can dry out the skin, while lower concentrations may not effectively eliminate germs.
Safe use of hand sanitizer
To reduce the risk of alcohol poisoning, especially among children, always use adult supervision when applying sanitizer. Here are some tips for safe use:
- Apply a small amount to the palm of one hand.
- Rub thoroughly over all fingers and hands until dry.
- Avoid touching food until the alcohol has fully evaporated.
- Store in limited access areas away from young age groups.
- Check packaging for expiration dates and ingredient data.
Additional ingredients for skin care
To keep hands from becoming dry, some many hand sanitizers include essential oils and vitamin E for hydration. These ingredients help maintain clean hands while preventing irritation.
When to use hand sanitizer
Use sanitizer when soap and water are unavailable, especially in public territories or after touching high-contact surfaces. If you feel sick, disinfecting hands frequently can help prevent spreading illness to another person.
