Last year, Nature Chemistry published an article by Alexander F. G. Goldberg and CJ Chemjobber titled “A comprehensive overview of chemical-free consumer products“. Everyone should read it. It’s a thorough description of all chemical-free products, and the paper itself is a free download. Here’s the introduction.
Manufacturers of consumer products, in particular edibles and cosmetics, have broadly employed the term ‘Chemical free’ in marketing campaigns and on product labels. Such characterization is often incorrectly used to imply — and interpreted to mean — that the product in question is healthy, derived from natural sources, or otherwise free from synthetic components. We have examined and subjected to rudimentary analysis an exhaustive number of such products, including but not limited to lotions and cosmetics, herbal supplements, household cleaners, food items, and beverages. Herein are described all those consumer products, to our knowledge, that are appropriately labelled as ‘Chemical free’.
It really is complete. But don’t worry, it won’t take you long to read it.
