A woman in California has successfully sued Johnson & Jonson because of ovarian cancer which she claims was caused by talc.
Another 2 such cases were thrown out because the judge stated that there was no reliable evidence that talc leads to ovarian cancer.
Talc is Magnesium Silicate with the formula Mg3Si4O10(OH)2.
Chrysotile is Magnesium Silicate with the formula Mg3Si2O5(OH)4. This is commonly called white asbestos. Interesting, n'est pas?
