In natural perfumery, what is the role of a 'fixative'? Which base note essential oils (e.g., Vetiver, Patchouli) or resins (e.g., Benzoin) serve as excellent natural fixatives?

The Role of Fixatives in Natural Perfumery

Hey there! I've been in the fragrance enthusiast circle for several years, and natural perfumery is truly fascinating. Simply put, in natural perfumery, a "fixative" acts like a "stabilizer" that helps the scent last longer. You know how perfume scents gradually fade after application, right? That’s because different essential oils evaporate at varying speeds—some disappear quickly. The fixative works like an "anchor," holding onto those fleeting notes to create a more balanced, long-lasting fragrance. It also helps blend the scent more harmoniously and prevents it from turning sour. In short, it makes your homemade perfume smell more professional and enduring.

What Can Be Used as Natural Fixatives?

Natural fixatives typically come from base note essential oils or resins, which evaporate slowly and have deep, long-lasting scents. Some excellent examples I often use include:

Vetiver: My personal favorite! It has an earthy, woody aroma that anchors the entire fragrance, making the perfume last for hours. Perfect for earthy-style perfumes.
Patchouli: A classic oriental fixative with a slightly earthy and sweet scent—excellent at "locking in" other notes. I always add it to woody blends.
Benzoin: A resin with a vanilla-honey fragrance. Its sticky texture makes it ideal as a fixative. It not only stabilizes the scent but also adds softness to the perfume.

Beyond these, I also recommend trying Sandalwood or Myrrh. They’re base note oils or resins with top-notch fixing power. Remember: don’t overuse them. Typically, 10–20% of your total formula is enough—any more, and they’ll overpower other notes. If you’re just starting out, experiment with small batches to test the results.
