We do not cover perfumes specifically in our courses. We have written some blogs on this topic which you may find useful. See the following articles:

If you would like to learn more about essential oils (used in natural perfume making) this is a topic covered in our courses. We cover how to choose which essential oils to use, the therapeutic properties of essential oils, their contraindications, and how to blend essential oils. We also cover calculating safe usage levels and, in our more advanced courses, how to calculate allergen levels.
