Continuous Process for Oakmoss Extraction

Oakmoss (Evernia prunastri L. Ach.), along with other tree mosses, is among the most voluminous botanicals which are solvent extracted for use in perfumes. These extracts are manufactured with heavy labor costs. Large quantities of solvent have to be circulated and evaporated. This requires high energy costs. Therefore, there is a place for a quicker continuous automated process.
