It's irritating isn't it? These statements of the bleedin' obvious are to prevent the Chav fraternity from buying a bag of nuts, having an allergic reaction and then suing the manufacturer because there was no warning on the label.

My bugbear is those poncey shampoos which list "Aqua" and "Parfum" amongst the ingredients... Why can't they just say "Water" and "stuff what smells nice"?
