Which of the following chemicals does a hand sanitiser generally contain?

Correct option is C

The correct answer is (C) Isopropyl alcohol

Explanation:

Isopropyl alcohol is a common ingredient in hand sanitizers. It is effective in killing bacteria and viruses by denaturing proteins and dissolving lipids, making it one of the most widely used alcohols in disinfecting products, including hand sanitizers.

Information Booster:

1. Isopropyl alcohol is typically used in concentrations ranging from 60% to 95% in hand sanitizers to effectively kill germs and viruses.

2. It works quickly, making it an essential component in hand hygiene, especially in situations where soap and water are not available.

3. Alcohol-based sanitizers are effective against a wide range of pathogens, including many bacteria and viruses, but they are less effective against some pathogens like norovirus and Clostridium difficile.

4. Isopropyl alcohol is a fast-evaporating substance, leaving hands feeling dry and clean after use.

Additional Information:

•  Calcium carbonate: This is used in products like antacids, but not in hand sanitizers.

•  Aluminium chloralhydrate: This chemical is used in antiperspirants, not hand sanitizers.

•  Diethyltoluamide: Also known as DEET, it is used in insect repellents, not in hand sanitizers.
