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.
A patch test study found that DMDM hydantoin in cosmetic products could increase the risk of cosmetic dermatitis. [13] Some people have a contact allergy to imidazolidinyl urea causing dermatitis. [14] Such people are often also allergic to diazolidinyl urea. In 2005–06, it was the 14th-most-prevalent allergen in patch tests (3.7%). [15]
Often released into products by the use of formaldehyde releasers such as imidazolidinyl urea, diazolidinyl urea, Quaternium-15, DMDM Hydantoin, and 2-bromo-2-nitropropane-1,3-diol. Fragrance mix – group of the eight most common fragrance allergens found in foods, cosmetic products, insecticides, antiseptics, soaps, perfumes, and dental ...
Hydantoin, or glycolylurea, is a heterocyclic organic compound with the formula CH 2 C(O)NHC(O)NH. It is a colorless solid that arises from the reaction of glycolic acid and urea . It is an oxidized derivative of imidazolidine .
The EWG removes electron density from a π system, making it less reactive in this type of reaction, [2] [3] and therefore called deactivating groups. EDGs and EWGs also determine the positions (relative to themselves) on the aromatic ring where substitution reactions are most likely to take place.

An electron-withdrawing group (EWG) is a group or atom that has the ability to draw electron density toward itself and away from other adjacent atoms. [1] This electron density transfer is often achieved by resonance or inductive effects.
DBDMH (also known as 1,3-Dibromo-5,5-Dimethylhydantoin) is an organic compound derived from the heterocycle called dimethylhydantoin.This white crystalline compound with a slight bromine odor is widely used as a disinfectant used for drinking water purification, recreational water treatment, as a bleaching agent in pulp and paper mills, and for treating industrial/commercial water cooling systems.
