About

Dedm Hydantoin is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

DEDM hydantoin (dimethylol dimethyl hydantoin) is a formaldehyde-releasing preservative widely used in cosmetics. While effective against bacteria and fungi, it is restricted under EU Annex III and carries sensitisation potential. The formaldehyde-release mechanism is the primary regulatory concern in the EU. At permitted concentrations, it is considered safe but must be labelled as a formaldehyde-releaser.
