The Dirty Thirty. A Reprised Dirty Dozen… 30 Bad Boy Chemicals!
At Keys, we have a core philosophy to not use any chemicals in our products that remotely have health concerns, known allergens or irritants. Like many, we started our business based on a need and we try to minimize negative marketing. If we were to list all the no’s, it would fill an entire web page. We chose to use the term chemical-free although it outrages the chemists of the world. All of our ingredients are on the labels and listed with the EWG Skin Deep Report.
So the purpose of writing about the Dirty Thirty is to give you an education of what chemicals are typically used in skincare, what they are intended to do and why you do not want to have them in your products.
Our own list of no no chemicals and natural ingredients tops 1100. Yes, some are natural and they are on our no-use list because they are too aggressive, too toxic or too useless because of efficacy or quality. This article is about the Real Dirty Thirty chemicals that top the bad-boys list.
A number of years ago, a few concerned people in Marin County California wondered why cancer rates were so high in their community. With the support of George Lucas and at the hand of Judy Shils, the Marin County Cancer Project was born. One of the first things that they realized was that there were certain chemicals used in personal care products. The identified them as contributing to elevated cancer rates and tagged them with the name, “The Dirty Dozen.” Many of these chemicals are now known to be harmful and the research a direct response to the efforts of the Marin County Cancer Project.
Now known as the “Search For the Cause”, the project realized that they must influence the younger members of our community and created another organization called “Teens Turning Green”. This group has now carried on the tradition and has expanded the list to thirty.
We are pleased to present the Dirty Thirty as chemicals of grave concern in everyday personal care and household products.
Note: Keys scientists have reviewed this list and have noted research papers on each chemical showing evidence of the claims below. We note that it is the burden of the manufacturers of human and pet products that use these chemical to prove to a point of certainty to their customers that these chemicals are safe. We support continued research and testing on all ingredients whether they are synthetic, organic or natural for safety and toxicity. Keys do not use any of the Dirty Thirty Chemicals based on questionable danger to humans and animals.
