Here’s an interesting resource I just found this week: CSPC. It is a database of cosmetic ingredients known to cause harm in humans. There is also an online reporting area.
Personally, I believe that there is so much noise in the conversation about toxins in the environment that it gets hard to hear the true signal (signal to noise ratio is radio engineering lingo for you young-’uns). This link is pure signal, no noise.
Thanks to the Breast Cancer Resource Center of Tacoma for bringing this one to my attention.
