Asbestos: Well, this was fun to learn about. Asbestos, a carcinogen, occurs naturally in close proximity to talc. So, anything with talc in it could theoretically contain asbestos. While the FDA has looked into it, neither substance is actually banned from cosmetics. Here’s a direct quote about the FDA’s stance on asbestos: “Both talc and asbestos are naturally occurring minerals that may be found in close proximity in the earth. Unlike talc, however, asbestos is a known carcinogen. For this reason, FDA considers it unacceptable for cosmetic talc to be contaminated with asbestos.” So, basically, the FDA thinks it’s unacceptable to have a known carcinogen in beauty products, but not so unacceptable that they would go so far as to legally restrict it.
