Ozone sterilisation heralds safer, longer life products

Maker seeks industrial partners to scale up to full manufacture

Scientists in Scotland have developed a novel way to make packaged personal care products safer by exploiting the germicidal power of ozone, a form of oxygen. Researchers at Glasgow University say the electrical 'plasma' method safely turns some natural oxygen inside sealed packaging into ozone, which sterilises microbes on contents then reverts spontaneously to oxygen. Independent tests showed increased shelf life for products and a significant reduction of pathogens.

The method is being marketed by Anacail, a spin-out company seeking industrial partners to scale up to full manufacture. “We're very excited about the applications. It's safe and easy to use and doesn't require any chemical additives,” Anacail CEO Dr Ian Muirhead said.
