- Type and Composition: Most effective and recommended sanitizers are alcohol-based (ABHS), containing between 60% and 95% alcohol (ethanol, isopropanol, or n-propanol). These high alcohol concentrations denature proteins and dissolve the lipid membranes of microorganisms, effectively inactivating them. Many formulations also include emollients like glycerin or aloe vera to prevent skin dryness caused by alcohol.
- Effectiveness: When used correctly on hands that are not visibly dirty or greasy, alcohol-based sanitizers can quickly reduce the number of germs by 99.9% or more.
Use
The primary use of hand sanitizer is for hand hygiene to prevent the spread of infectious diseases.
- Convenience: It is a quick, portable, and convenient alternative to hand washing when a sink is not readily available, such as when traveling, in public places (markets, gyms, schools), or in certain work environments like healthcare settings (hospitals, clinics).
- Application: To use it effectively, apply the recommended amount (check the label for the correct dosage) to the palm of one hand and rub the product over all surfaces of both hands and fingers until the hands are completely dry. This process should take at least 20-30 seconds.
