This project uses innovative new technology to measure the effects of different messages on levels of hand-washing with soap. The study is being piloted at Unilever’s Research and Development facility, and will be implemented in public toilets in motorway service stations.

There have been a lot of different ideas about how to change people’s behaviour. Some of these will be put to the test in our study. By installing sensors which measure how many people enter public toilets, and what proportion of these use soap, we can see which interventions lead to the greatest increase in hand-washing with soap after toilet use.

The results from this study can be used to inform future campaigns promoting hand-washing.
