DMDM hydantoin
DMDM hydantoin (Glydant) is an allergen and formaldehyde-releasing preservative. DMDM hydantoin releases formaldehyde under regulation by multiple factors and with enhanced release in alkaline environments. DMDM hydantoin induces allergic contact dermatitis via type-IV delayed hypersensitivity, either directly or through released formaldehyde. DMDM hydantoin is a broad-spectrum preservative that is effective against fungi, yeast, and gram-positive and gram-negative bacteria. DMDM hydantoin can be used in cosmetics industry production research (e.g., shampoos, hairsprays, and skincare products) and can be used for research on allergic contact dermatitis.
