Talcum powder is made from talc, a mineral containing magnesium and silicon that are mined in rock form. It is marketed to absorb moisture and also to provide soft, slippery surfaces that reduce friction.
For years, medical professionals knew that talcum powder was dangerous for babies and children to breathe. Now women claim in lawsuits that the fine-powder products gave them ovarian cancer. Lawsuits have been filed against Johnson & Johnson, the distributor, for failure to warn.
