What is Ethyl 3-ethoxypropionate?
Ethyl 3-ethoxypropionate (CAS 763-69-9), commonly known by the abbreviation EEP, is a slow-evaporating ester solvent used across coatings, personal care, and specialty chemical formulations.
Where is Ethyl 3-ethoxypropionate used?
- Coatings and inks: improves flow and leveling in high-solids and waterborne systems, helping meet VOC targets
- Personal care: carrier solvent in nail lacquers, hair care and skin formulations
- Industrial cleaning and surface preparation: dissolves resins, adhesives and polymer residues
- Flavor and fragrance: minor component contributing ester character
- EEP dissolves resins, adhesives and polymer residues where faster solvents would evaporate before adequate penetration.
Commercial specifications
- Clear liquid in drum and IBC quantities; bulk tanker options for larger volumes
- Technical grade standard; high-purity grades for personal care and fragrance
