What problems should be paid attention to when using hand sanitizer?

Hand sanitizer is a kind of skin care cleanser used to clean the hands. It removes the dirt and attached bacteria on the hands through the action of mechanical friction and surfactants, with water flow or without water. ​But what problems should you pay attention to in the process of using hand sanitizer? 1. Be careful of causing fire. Because hand sanitizer generally contains alcohol, it will burn in the event of an open flame. Therefore, hand sanitizer should be kept in a place every day, and should not be placed in high temperature and exposure to the sun. When using it, remember to keep it away from fire sources. 2. Alcohol poisoning caused by accidental ingestion. Children may swallow hand sanitizers with fragrance, bright colors and beautiful packaging. Hand sanitizer should be stored out of the reach of children and used under adult supervision. 3. When the hands are very dirty or greasy, the effect is greatly reduced. Use the hand sanitizer when the hands are slightly dirty, which has a good effect on some microorganisms. However, hand sanitizer may not work properly when hands are very dirty or greasy, in which case water is recommended. 4. Long-term use will irritate the skin Disposable hand sanitizers generally use ethanol as an active ingredient. Doctors believe that long-term use will stimulate and damage the skin barrier.
