Question: can i bring isopropyl alcohol on a plane?
Answer: Yes, you can take rubbing alcohol in your carry on luggage. It's a liquid so it must be in containers smaller than 3.4 oz or 100 ml. You also need to put it on your quart size toiletries bag along with your other liquids. The 70% alcohol rule only applies to alcoholic beverages and rubbing alcohol is NOT a beverage.
