Category

Biocides/Disinfectants

Sources/Uses

Used as a biocide in cosmetics with 0.6% the maximum allowable concentration in the EU; [Kanerva, p. 398, 407] Used as an antimicrobial pesticide in cleaning products, adhesives, air fresheners, caulks, hydraulic fluids, inks, metal working cutting fluids, paints, stains, coatings, paper and paperboard coatings, polishes, synthetic polymers, sealants, starch solutions, resin emulsions, textiles, and wax; [Reference #1]

Comments

A formaldehyde releaser used in cosmetics; It can cause allergic contact dermatitis; "Rinse off products in general will have a low risk of causing allergic contact dermatitis." [Kanerva, p. 398-404] Reports of positive results for skin sensitization patch testing; [HSDB] A formaldehyde releasing agent present in combination with MDM hydantoin (CAS# 116-25-6) in the commercial product 2,4 Imidazolidinedione; Likely hydrolyzes/degrades to 5,5-dimethylhydantoin (DMH); [Reference #1] See "5,5-Dimethylhydantoin" and "Formaldehyde."
