Ever heard of phthalates? Nasty little molecules that mimic & disrupt our hormones. And you don't need them in your perfume. Go 'green' with your perfume.
The alternative to commercially manufactured fragrances is Natural Perfumery. Mostly plant based, and made from ingredients found in nature. When thoughtfully combined, sophisticated aromas can be created just for you. Even BY you.
Some natural perfumes take months to make... starting with oils that create a middle 'accord', or a complex 'base'.
And some are pretty sophisticated with just three essential oils: for example Bunny is benzoin, ylang ylang and a drop of bergamot. And it is powdery; a youthful musk.
Some of the best information on modern natural perfume is by Mandy Aftel creator of Aftelier Perfumes and the author of Fragrant (a 'workbook' and tour of natural perfume).
