Do soap-free cleansers work as well as soap?

The great news is...yes! Both soap and soap-free cleansers do exactly the same thing; they clean the skin and work by lifting dirt and contaminants from the skin.

The difference is in how the products are made and the ingredients that are used, not in their effectiveness. Soap, owing to a naturally high pH, can be irritating to the skin, whereas non-soap based cleansers are usually pH balanced, so they are gentler on the skin. It's also important to note that if a soap and a soap-free cleanser both contain surfactants then they should produce the same effects - the only difference is the type of surfactant used (this can vary between products).

Something else that plays a very important part in hand hygiene? The act itself of washing your hands - rubbing your hands together can actually help to lift contaminants from your skin while you wash. It's for this very reason that washing your hands thoroughly for at least 20 seconds remains the preferred method for hand hygiene by the World Health Organisation.

Associate Professor Rosemary Nixon AM, Dermatologist and Occupational Physician from the Skin Health Institute echoes this recommendation and states, “It’s important to wash your hands frequently at this time. While soaps do a great job and are suitable for most people, others will find that their skin becomes easily irritated, especially if they have a history of eczema or contact dermatitis.

Instead, they should use soap substitutes which do the same job as soaps, but are gentler because they are balanced to the pH of the skin. Of course, moisturising the hands especially at night, to restore the skin barrier, is also really important”.
