To determine the correct percentage of alcohol that hand sanitizing gel should contain, let's consider the options given:
A) 10%
B) 60%
C) 25%
D) 99%
Hand sanitizing gels need to have a sufficient amount of alcohol to be effective in killing germs and bacteria. The Centers for Disease Control and Prevention (CDC) recommends using hand sanitizers with at least 60% alcohol.
Let's review each option:
- Option A) 10%: This percentage is too low to effectively kill germs and bacteria. It's not recommended.
- Option B) 60%: This percentage aligns with the CDC's recommendation for effective hand sanitizers.
- Option C) 25%: This is higher than 10% but still not sufficient. It is below the recommended minimum.
- Option D) 99%: While this is very high and could kill germs, it exceeds the standard requirement and could potentially be harsher on the skin.
From these evaluations, the correct choice is B) 60%. This percentage ensures the hand sanitizer is effective in sanitizing hands while also being safe for regular use.
