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 |
|---|---|---|---|---|
| natural nonanoyl | nonanoyl of natural origin + allyl alcohol from petrochemical synthesis | 0.71 | Nonanoyl fragment C9H17O 141.2/198.3 = 0.71. | |
| synthetic | nonanoyl and allyl alcohol both from petrochemical synthesis | 0.00 | No natural carbon. |
Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.
How we scored it
Allyl Nonanoate C12H22O2 198.3 Da: the nonanoyl fragment C9H17O 141.2 Da is natural only from a natural source; the allyl alcohol fragment 57.1 Da is petrochemical in every commercial route. Routes: natural nonanoyl 0.71, synthetic 0.00. Headline shows the best route.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Nonanoic acid (oleic-acid ozonolysis or oxo synthesis) esterified with petrochemical allyl alcohol.
In plain English
A fruity fragrance ingredient made from a plant-derived fatty acid joined to a petroleum-based alcohol. Mostly natural by weight.
Structure
prop-2-enyl nonanoate
