The Ethylene Urea - also known as 2-Imidazolidinone hemihydrate – is mainly used in various kinds of formaldehyde removing formulations such as high-effect formaldehyde removing detergents and long-term formaldehyde dissolution intermediates.
In the flavor and fragrance industry the product is used as a release control agent.
The pharma industry is using the product as an intermediate for antibiotics such as Mezlocillin and Azlocillin.
Main users are the leather, rubber, fragrance and textile coating industry.
Applications of Ethylene Urea
Ethylene Urea is an organic compound derived from formaldehyde and urea.
Ethylene Urea is a colourless solid that is used for treating cellulose-based heavy fabrics to inhibit wrinkle formation.
Ethylene Urea bonds with the hydroxyl groups present in long cellulose chains and prevents the formation hydrogen bonding between the chains, the primary cause of wrinkling.
This treatment produces permanently wrinkle-resistant fabrics and is different from the effects achieved from using fabric softeners.
Ethylene Urea is an organic intermediate used in various chemical industries.
Ethylene Urea was originally used for the production of dimethylol ethylene urea thermosetting resins in textiles and paper.
Ethylene Urea is also used as a scavenging agent to reduce the free formaldehyde in phenolic, melamine, glyoxal and urea formaldehyde resin systems for the coatings, construction and textile industries.
Application of Ethylene Urea:
Ethylene Urea can be very affective at scavenging formaldehyde in various resin systems.
Reduction of 75% can be achieved depending on application conditions and the resin system properties.
We recommend using Ethylene Urea in most applications.
The exact amount needed would depend on many variables, but laboratory experimentation should be performed to establish optimized dosage.
Applications of Ethylene Urea:
1. Textile industry
Cotton products are composed by long chain cellulose, which contains lots of hydroxyls to form spacious hydrogen bonds.
These hydrogen bonds will be broken and then randomly reformed under the heat or external forces.
That’s how the fabric folds come.
Ethylene Urea reacts with hydroxyl groups when treating fabrics together with formaldehyde, forming a stable structure to prevent the folds from forming.
This method can also restain the pungent odor caused from using formaldehyde only as the anti-wrinkle treatment by effectively inhibiting the release of formaldehyde.
Besides, Ethylene Urea is another widely used textile finishing agent.
Its residues on fabrics slowly release formaldehyde, which can be effectively inhibited by Ethylene Urea.
2. Coating and Paint
Ethylene Urea can be used as de-aldehyde agent in poly-EVA, all kinds of water-based coatings, paints, pigments, adhesives and paper industry.
Ethylene Urea can also be added to the paint alone to make the paint absorbing and decomposing formaldehyde.
3. Ink for inkjet printers
Ethylene Urea is an important additives of ink for inkjets.
Ethylene Urea can disperse the pigment, lubricate the channels, prevent nozzles from drying out and blocking, and imporve the storage stability of ink.
Ethylene Urea can also imporve the color contrast to enhance the printing effect.
Various types of 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 respectively.
All of them have the problem of slowly releasing gaseous formaldehyde into the environment.
Ethylene Urea can be added to effectively reduce the formaldehyde release and does not affect the bonding effect.
5. Daily Chemical
Ethylene Urea is the main composition of household de-aldehyde agent.
Ethylene Urea can be used as 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
Ethylene Urea can be used as intermediates of many new antibiotics, such as meloxicillin and aloxicillin, as intermediates for anti-schistosomiasis drugs, and as basic raw materials of third-generation penicillin.
In the biological field, Ethylene Urea can be used to produce the 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.
