Why water-based hand sanitisers can cause antibiotic resistance

In order to save water, Capetonians were told to use hand sanitisers instead of water. But do hand sanitizers really work?

Allergist and immunologist, Dr Adrian Morris says there are two types of sanitisers, the water-based and alcohol-based.

Morris says the biggest concern is with the water-based sanitizers.

He says the water-based sanitisers contain an ingredient that could lead to antibiotic resistance over time called triclosan. The alcohol-based sanitiser has about 60 percent of alcohol which kills bacteria but it leaves the skin a bit dry.

To use sanitisers, your hands 'need to be dry and gunk free', says Morris. If not just use water and soap to keep them clean.
