Intermediate Level Natural Perfumery Course Syllabus


NOTE: you must have received a certification diploma from the Natural Perfumery Institute to enroll in the Intermediate Course, or have permission from the Institute to enroll. Please use the contact page to confirm eligibility before enrolling.


  • You’ve made a beautiful perfume, using drops, either diluted or undiluted. You need to learn specific gravity to be able to scale up that perfume in volume. We teach a fun, easy way to work with specific gravity, and you’ll know the cost of every batch, down to the penny.
  • Inexpensive laboratory equipment makes perfume creation easy. The module on laboratory equipment will open your eyes to help simple gadgets can make in your studio.
  • Comparing and contrasting aromatic oils is necessary to allow you to see the interactions and reactions they have with each other. It’s more than accord-building, it’s scent memory building and exploring all possible accords.

These oils weigh the same but notice the difference in volume. Learn how to convert drops to weight to accurately scale up perfume amounts successfully. An Excel.xls program is provided to the students so they can quickly calculate the strength of perfume (in percent), cost of the oils and alcohol, in any volume. Necessary for a perfume business, because scaling up drops won’t work for increased volume production.


There are several core learning modules that all are required to take and one elective.


Core Syllabus:

1. Specific Gravity

– Working with specific gravity program and converting all of the aromatics in your organ to usable items with specific gravity and cost built into an Excel blending worksheet. The Excel worksheet was designed by Anya McCoy and an engineer and is copyrighted.

2. Compare and Contrast

– Extensive compare and contrast evaluations on aromatics, complex, and different from the accord studies in the Basic Course.

3. Laboratory Equipment

– Using various laboratory equipment and devices in perfumery, including an ultrasonic machine for tinctures, (and also for aging modifications.) Learn how to use conductivity meters, filtration devices, separatory funnels, and more.

Tuition is $2000 and the time frame is one year or less. A diploma of certification that the Intermediate Level has been successfully completed will be awarded.
