There have been cases of benzene being detected in sunscreen. It's not an intentional ingredient, just one that is common in industrial manufacturing. I don't think that's what the parent was worried about though.
No, benzene was specifically what I was thinking of to the point that I assumed it was so well known that it wasn't question as being a thing any more. Just like asbestos in baby powder
That’s thankfully no longer really a thing - the world has realised that there is no such thing as asbestos-free talc, so baby powder is now mostly corn-starch AFAICT.
Okay, and? If you can’t see a difference in benzene as a byproduct vs an ingredient people lather in their skin and rub in sold as a way to protect against skin cancer while giving you chances of a different cancer as something totally different, then your being deliberately obtuse and not contributing to this conversation in any meaningful way.
