Which type of alcohol is commonly used as a disinfectant and is not safe for consumption?

Isopropyl alcohol, also known as isopropanol, is commonly used as a disinfectant in various settings, including healthcare and households. It is effective in killing bacteria, fungi, and viruses, making it suitable for cleaning surfaces and sanitizing hands when used in appropriate concentrations, typically around 70%.

Unlike ethyl alcohol, which is the type of alcohol found in alcoholic beverages and is safe for consumption in moderate quantities, isopropyl alcohol is toxic if ingested. Consuming isopropyl alcohol can lead to serious health complications, including poisoning, which is why it is not considered safe for human consumption.

The other types of alcohol mentioned, such as methyl alcohol (methanol) and butyl alcohol, also pose significant health risks. Methanol is highly toxic and can cause blindness or death, while butyl alcohol is primarily used as a solvent and can also be harmful if ingested. However, isopropyl alcohol is specifically recognized for its widespread use as a disinfectant and its toxicity upon ingestion, solidifying its identification as the correct response in this context.
