I am very curious about the safety hazards concerning talc, particularly when it is used as an ingredient in personal care products and makeup. There used to be concerns about it being carcinogenic (lung and ovarian cancer) but it seems that these ideas have now been dismissed as only being relevant when talc is contaminated with asbestos. However, on your website you write that there is a diseases associated with inhaling talc? Could you please explain this a little further? Why do you advise to was one's hands after handling solid talc?
