 I'm Peter Taylor and I'm an organo-silicon chemist. Here's some silicon and when you oxidize it you get silica, sand. But if you treat it appropriately with organic groups you get silicones and they're the things you use to seal your bath. But silicones have a whole range of other uses. They're used for cupcake holders for baking. They're used for in contact lenses. They're used in the materials you treat your brick with to make them damp proof. And we do a whole range of work with organo-silicon materials. Here's some of the resins that you make and we're also interested in silicones. They're used in personal care products, in particular in kind of hair shampoo and the like. Something which is obviously pretty important to me.
