Why the score varies
This ingredient is made commercially by more than one route, and ISO 16128 scores the feedstock actually used. Without a supplier certificate of origin the value cannot be claimed.
| Route | Feedstock | NOI | Share | Notes |
|---|---|---|---|---|
| Synthetic citral + 2-butanone, acid cyclisation | isobutylene, formaldehyde and butene-derived 2-butanone (petrochemical) | 0.00 | ~80% | |
| Natural-origin citral + 2-butanone, acid cyclisation | Litsea cubeba oil or pine-terpene citral with petrochemical 2-butanone | 0.66 | ~20% |
How we scored it
Where it comes from
Dominant route: synthetic citral (from isobutylene and formaldehyde) is condensed with petrochemical 2-butanone and cyclised with acid, giving 0.0. Alternative: citral from Litsea cubeba oil or pine terpenes goes through the same steps, giving 0.66.
In plain English
Violet- and woody-smelling fragrance materials made by joining citral with butanone and closing a ring with acid. They add a powdery floral note to perfumes. The citral can come from essential oils such as Litsea cubeba or be made from petrochemicals.
