Dimethylol ethylene urea
Dimethylol ethyleneurea is an organic compound derived from formaldehyde and urea. It is a colourless solid that is used for treating cellulose-based heavy fabrics to inhibit wrinkle formation. Dimethylol ethylene urea (DMEU) bonds with the hydroxyl groups present in long strain cellulose chains and prevents the formation hydrogen bonding between the chains, the primary cause of wrinkling.
