Scientists are developing innovative soaps and deodorants to make us even cleaner.
The ‘super soap’, developed by a team at the Colgate-Palmolive Technology Centre in Piscataway, New Jersey, reduces the amount of bacteria which attaches itself to the skin.

The deodorant, from Unilever Research and Development Laboratory, Port Sunlight, UK, works on the basis that bacteria in the armpit need the iron in sweat to produce body odour, so depriving them of iron reduces the smell.

Both developments were presented to a meeting of the American Society for Microbiology in Salt Lake City.
