Talcum is dangerous. Stay away from Johnson & Johnson or any other company’s who sell baby powders or anything containing talcum. It’s not worth it. Even if something isn’t “proven” by science, even a small percentage isn’t worth the risk of endangering you or your kin. You can find an alternative. Redmond clay is a great alternative. Salt-wise, Himalayan salt is much better!
A little bit about Talcum Powder:
Pulmonary issues, lung cancer, and ovarian cancer. One of these, published in 1993, was a US National Toxicology Program report, which found that cosmetic grade talc containing no asbestos-like fibres was correlated with tumor formation in rats forced to inhale talc for 6 hours a day, five days a week over at least 113 weeks. A 1971 paper found particles of talc embedded in 75% of the ovarian tumors studied.
One particular issue with commercial use of talc is its frequent co-location in underground deposits with asbestos ore, which often leads to contamination of powdered talc products with asbestos fibers. Stringent quality control since 1976 (separating cosmetic and food-grade talc from “industrial” grade talc, which is allowed a certain portion of asbestos contamination) has mostly eliminated this issue, but it remains a continuing hazard requiring mitigation in the mining and processing of talc.
The US Food and Drug Administration (FDA) considers talc (magnesium silicate) to be generally recognized as safe (GRAS) for use as an anti-caking agent in table salt in concentrations smaller than 2%.
