DMDM Hydantoin (formaldehyde-releaser)
Flagged in 2
Scout's take
DMDM Hydantoin is a preservative that slowly releases formaldehyde — a Group 1 known human carcinogen (IARC) — in the product to prevent microbial growth. The formaldehyde release exposes scalp and respiratory tract during application. Banned or restricted in cosmetics in the EU and several US states.
