Uses of talc: Talc is used in a wide variety of products that we see every day. It is an important ingredient in rubber, a filler and whitener in paint, a filler and brightening agent in high-quality papers, and a primary ingredient in many types of cosmetics.
Lung disease, including lung cancer, is another concernâbut primarily in workers who inhale talc dust particles during mining and processing. A few cases of serious lung problems have been reported from chronic overuse of cosmetic talc products. Bottom line: To be on the safe side, donât use talcum powder. If you want to use it on occasion, do so only in a well-ventilated room and limit how much you apply; women shouldnât use it in the genital area. As an alternative, switch to cornstarch-based prodÂ­ucts.
