Which is a better bacteria killer? Bleach or hand sanitizer which contains 62% ethyl alcohol.

i'm not sure but i think is the hand sanitizer.

hand sanitizer

ok thanks.

What kind of germs? What temperature? In any case, I think bleach would be hard to beat but I have no proof of that. Of course, one can't wash their hands in bleach. Ouch! The sanitizer companies advertise that ethyl alcohol, the priniciple ingredient in hand sanitizers (usually with skin softeners and emolients added) kills 99% of germs. But bleach, especially chlorine bleach, is a disinfectant. Do a little research and consult other resources before you make a decision.

To determine which is a better bacteria killer between bleach and hand sanitizer, it is important to consider a few factors:

1. Type of germs: Different disinfectants may be more effective against specific types of germs. For example, bleach is especially effective against many common bacteria, viruses, and fungi, while hand sanitizers with at least 60% alcohol are effective against a wide range of pathogens, including some viruses and bacteria.

2. Concentration of active ingredients: The effectiveness of a disinfectant depends on the concentration of its active ingredients. Bleach typically contains sodium hypochlorite as the active ingredient, while hand sanitizers usually contain ethyl or isopropyl alcohol. Both bleach and hand sanitizers with at least 60% alcohol are effective disinfectants, but the specific concentration needed may vary depending on the target germs.

3. Exposure time: The effectiveness of a disinfectant can also depend on the duration of contact with the germs. Bleach typically requires a longer contact time (around 10 minutes) to effectively kill germs, while hand sanitizers with at least 60% alcohol can rapidly kill germs within seconds.

4. Temperature: The temperature can also affect the effectiveness of disinfectants. Bleach is generally effective across a wide range of temperatures, while the efficacy of alcohol-based hand sanitizers may decrease in extreme cold temperatures.

Considering these factors, both bleach and hand sanitizers with at least 60% alcohol can be effective bacteria killers. Ultimately, the choice between them depends on the specific situation, the type of germs you are trying to kill, and the availability of products. It is always a good idea to consult reliable sources and do further research to make an informed decision.
