What is Ethylene glycol monopropyl ether?
Ethylene glycol monopropyl ether (CAS 2807-30-9) is a slow-evaporating glycol ether solvent. Also marketed as Propyl Cellosolve.
Where is Ethylene glycol monopropyl ether used?
- Coatings: improves flow and leveling in architectural and industrial systems
- Alkyd and waterborne formulations: reduces brush marks and orange peel
- Printing inks: controls drying speed and maintains viscosity stability, particularly for packaging inks on flexible substrates
- Personal care: carrier solvent in hair care and skin formulations for uniform ingredient dispersion
- Adhesives and sealants: coalescing or coupling solvent that improves substrate wetting and bond development
- Its controlled evaporation rate supports film formation and flow where faster solvents cause surface defects.
Good to know: High-purity grades are available for personal care and specialty formulation use where tighter quality specifications are required.
Commercial specifications
- Drum and IBC quantities; bulk tanker options for high-volume buyers
