DMDM hydantoin is an antimicrobial formaldehyde releaser preservative with the trade name Glydant. DMDM hydantoin is an organic compound belonging to a class of compounds known as hydantoins. It is used in the cosmetics industry and found in products like shampoos, hair conditioners, hair gels and skin care products.[1][2]

DMDM hydantoin works as a preservative because the released formaldehyde makes the environment less favorable to the microorganisms.

Safety[edit]

A patch test study found "An increase in the use of DMDM hydantoin in cosmetic products will also inevitably increase the risk of cosmetic dermatitis in consumers allergic to formaldehyde."[3] DMDM hydantoin may cause allergic contact dermatitis to the product itself, cross-react with other formaldehyde releasing compounds or due to the formaldehyde released.[citation needed]
