TalcAnti-caking

IARC classifies cosmetic-grade talc not containing asbestos as Group 2B (possibly carcinogenic to humans); perineal talc use as Group 2A (probably carcinogenic). Johnson & Johnson voluntarily withdrew talc-based baby powder from US/Canada in 2020 and globally in 2022 after extensive litigation tied to ovarian-cancer and mesothelioma cases. The 2018 FDA contamination survey found asbestos in 9 of 52 cosmetic talc products tested. As a supplement excipient talc is a pure manufacturing convenience — no nutritional or functional benefit to the user — so the asbestos-exposure risk has no offsetting upside. Safer alternatives (silicon dioxide, microcrystalline cellulose, rice hulls) are widely available.
