Ethyl 3-ethoxypropionate

CAS: 763-69-9

Overview

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.

Its controlled evaporation rate and strong solvency make it a preferred choice for applications requiring extended open time and clean substrate wetting during the application process.

In coatings and ink formulations, EEP improves flow and leveling in high-solids and waterborne systems, helping formulators meet VOC targets without sacrificing film quality or performance.

Personal care manufacturers incorporate it as a carrier solvent in nail lacquers, hair care products, and skin formulations where a slow-drying, low-odor profile is required for the consumer.

In industrial cleaning and surface preparation, EEP dissolves resins, adhesives, and polymer residues where faster solvents would evaporate before adequate penetration into the substrate occurs.

It also appears in flavor and fragrance applications as a minor component contributing ester character to finished compositions, ensuring a balanced profile in the final aromatic product.

Ethyl 3-ethoxypropionate is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for larger procurement volumes to meet industrial demand.

Technical grade is the standard commercial offering, with high-purity grades available to meet formulation-specific requirements in personal care and fragrance end uses globally.
