Anya's Garden Natural Perfumery Institute - Extraction Methods and Products

Cold Enfleurage - Vietnamese gardenias from Anya's Garden

I recently blogged about production methods in the aromatics industry, and how important it is for students of the Natural Perfumery Institute to be knowledgeable about them.  A basic course needs to cover these topics so that the student perfumer will be able to converse and communicate intelligently and effectively about the sources of the aromatics used in our art.

Many students, if ambitious, can extract aromatics from plant material, animal derivatives and soil themselves if they wish.  Here is a list of the topics covered in Module 2 of my textbook.
