Just published the other day by a part of Nature Publishing Group is a review by two scientists of the chemical-free products available to consumers. Here's the abstract for the review.
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’.The free-to-access PDF is here.
I hope this diary and linked review is of some use to those looking for chemical free products for the summer.
