This is a great blog post from The Sceptical Chymist – part of the Nature Chemistry blogosphere. It relates to a page published in Nature Chemistry which illustrates the absurdity of the phrase ‘chemical-free’ which has no doubt irritated any lover of the chemical sciences for years.
I myself feel at my wit’s end by all the television adverts and product packaging which claim their product to be ‘chemical-free’ as the word ‘chemical’ is continued to be demonised by the media and advertising world. We’re bombarded with the notion that ‘chemicals’ are bad – they’re poisons which we want to avoid at all cost and surely any product that lowers there use must be superior. Unfortunately, the general public accept this notion willingly, and are perhaps unaware that thousands of items they use every single day of their lives – medicines, fuel, plastics, cosmetics, food – are all made up of useful chemicals which would be sorely missed if they were removed.
In short – the ‘chemical-free’ label is purely a myth.
I strongly suggest you take a peek at the article – it won’t take long!
