While washing hands with soap is considered to be the most effective way to practice good hand hygiene during the COVID-19 pandemic, hand sanitisers can play an important role in keeping hands as free from harmful microorganisms as possible.
How hand sanitisers work
Hand sanitisers contain antiseptic ingredients. An antiseptic is a substance that is used on the skin to kill microorganisms or prevent the growth of microorganisms.
Hand sanitisers can be either hand washes for use with water or handrubs for use without water, and are regulated as either a cosmetic or therapeutic good (see below) depending on how they are used, what they contain and what they claim to do.
