2-Imidazolidone (Ethylene Urea) can be used as an anti-crease, de-aldehyde, and crosslinking agent. It’s also the main component of air fresheners.

1. Textile industry

Cotton products comprise long-chain cellulose containing many hydroxyls to form spacious hydrogen bonds. These hydrogen bonds will be broken and randomly reformed under heat or external forces. That’s how the fabric folds come.

2-Imidazolidone (Ethylene Urea) reacts with hydroxyl groups when treating fabrics with formaldehyde, forming a stable structure to prevent the folds from forming. This method can also restain the pungent odor caused by using formaldehyde only as the anti-wrinkle treatment by effectively inhibiting the release of formaldehyde.

Besides, urea resin is another widely used textile finishing agent. Its residues on fabrics slowly release formaldehyde, which can be effectively inhibited by 2-Imidazolidone (Ethylene Urea).

2. Coating and Paint

2-Imidazolidone (Ethylene Urea) can be used as a de-aldehyde agent in poly-EVA, water-based coatings, paints, pigments, adhesives, and the paper industry. It can also be added to the paint alone to make the paint absorb and decompose formaldehyde.

3. Ink for inkjet printers

2-Imidazolidone (Ethylene Urea) is an important additive of ink for inkjets. It can disperse the pigment, lubricate the channels, prevent nozzles from drying out and blocking, and improve the storage stability of the ink. It can also improve the color contrast to enhance the printing effect.

4. Adhesive

Various artificial panels, such as plywood, chipboard, fiberboard, and composite panels, usually choose urea resin, phenolic resin, or melamine resin as adhesives.

Those adhesives are produced from polycondensation between formaldehyde and urea, phenol, or melamine. They all have the problem of slowly releasing gaseous formaldehyde into the environment. 2-Imidazolidone (Ethylene Urea) can be added to reduce the formaldehyde release effectively and does not affect the bonding effect.

5. Daily Chemical

2-Imidazolidone (Ethylene Urea) is the main component of the household de-aldehyde agent. It can be used as a high-performance formaldehyde remover, home air formaldehyde potent enzyme, formaldehyde long-acting melting medium, aldehyde remover for glue, photocatalyst, floor deodorization care wax, furniture deodorizer, car deodorizer, etc.

6. Organic Synthesis

2-Imidazolidone (Ethylene Urea) can be used as intermediates of many new antibiotics, such as meloxicillin and aloxicillin, for anti-schistosomiasis drugs, and as basic raw materials of third-generation penicillin.

In the biological field, it can produce plant growth regulators, fungicides, inhibitors, herbicides, etc., such as N-chlorocarbonyl-2-imidazolidinone, 1-chlorocarbonyl-3-acetyl-2-imidazolidinone, 1-chlorocarbonyl-3-methanesulfonyl-2-imidazolidinone N-chloroformyl-2-imidazolidinone, 1-chloroformyl-3-acetyl-2-imidazolidinone, 1-chloroformyl-3-methanesulfonyl-2-imidazolidinone, N-hydroxyethyl-2-imidazolidinone, 1-methanesulfonyl-2-imidazolidinone, 1,3-dimethyl-2-imidazolidinone, 1-acetyl-2-imidazolidinone, etc.
