Slow evaporation of solvent
WebbEastman™ EEP (Ethyl 3-Ethoxypropionate) is a slow evaporating ether-ester solvent with excellent activity for a wide range of coating polymers. Its linear structure and propionyl group in the center of the molecule give this material a combination of desirable properties not found in other solvents. These include a slow evaporation rate, good ... Webb11 apr. 2024 · They exhibited self-degradability due to the evaporation of solvent and sublimation of matrix forming agent. Sublimation of borneol was considered as an advantage for the ISM system because the drug entrapped in the borneol matrix formation could sustain release over time while matrix disappearance by non-invasive route.
