Rubbing alcohol is often used as a disinfectant and sometimes as a component of handsanitizers. If you were to purchase a bottle of rubbing alcohol at a store, it would most likely sayisopropyl alcohol or isopropyl rubbing alcohol, although it is also called isopropanol. Ethylalcohol is also used in hand sanitizers, and is actually more commonly used. Why would a handsanitizer whose major component is ethyl alcohol evaporate more quickly than one whose majorcomponent is rubbing alcohol?
