What it is
Ylang-ylang oil is distilled from the flowers of Cananga odorata, a tropical tree native across parts of Southeast Asia and northern Australia.
Unlike a simple one-pass essential oil, commercial ylang-ylang production is strongly associated with fractionation by distillation time.
Extra, I, II and III
Ylang-ylang is commonly sold in several grades or fractions. Earlier fractions contain a higher proportion of more volatile materials, while later fractions become richer in heavier sesquiterpenes.
That means Extra, I, II and III are related but not interchangeable smelling materials. A complete oil may combine multiple fractions into a broader representation.
What to notice
Ylang-ylang can suggest:
- creamy yellow-white flowers
- banana-like or tropical fruitiness
- sweet spice
- custard-like richness
- jasmine-like floral depth
- soft medicinal or phenolic traces
- heavier woody-floral depth in later fractions
The balance changes substantially with fraction and origin.
Keep the grade
When a formula or supplier specifies Extra, I, II, III or complete ylang-ylang, that should be retained in the source data. The grade is meaningful material information, not marketing decoration.
