About
A very hard abrasive used in industrial grinding and some exfoliating products — GHS classified as a suspected carcinogen when inhaled as fine dust. Handle with caution.
Silicon Carbide (SiC, CAS 409-21-2) is an extremely hard crystalline compound used as an abrasive in cosmetics and industrial applications. The significant concern is its GHS classification H350/H350i (may cause cancer by inhalation), which relates to respirable crystalline whisker/fiber forms. H372 indicates organ damage through repeated exposure. In cosmetic use as a scrub/exfoliant, dermal exposure is the primary route, which is less concerning than inhalation. However, the carcinogenicity classification for inhaled fibers/dust is a serious flag that warrants caution. CosIng lists it with an abrasive function.
