Verdict

Dermal absorption is vanishingly low (0.00052%) per gold-standard AMS microtracer study. SCCS/1662/23 confirmed safety at product-type-specific aluminum concentration limits. FDA OTC drug GRAS status for antiperspirant use. No CMR classification, no carcinogenicity link, no conclusive neurotoxicity or breast cancer association. Not COSMOS/ECOCERT certifiable. Align finished-product Al content with SCCS/1662/23 category-specific limits.

US Note

GRAS under OTC Monograph M019 (21 CFR Part 350); maximum 25% in antiperspirant products; regulated as OTC drug not cosmetic when used for antiperspirant claims; labeling must include kidney disease warning
