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 |
|---|---|---|---|---|
| Petrochemical synthesis | oxo-process pentyl aldehyde + acrylate-type unit, lactonised | 0.00 | ~65% | |
| Fermentation | castor-oil-derived hydroxy fatty acid beta-oxidised by Yarrowia lipolytica yeast, lactonised | 1.00 | ~35% |
How we scored it
Where it comes from
Can be produced by yeast fermentation of castor-oil-derived hydroxy fatty acids, trimmed and lactonised with every carbon traceable to castor oil. Alternatively synthesised from petrochemical aldehydes via oxo-synthesis and lactonisation; the synthetic route is assumed larger-volume.
In plain English
A coconut/creamy-scented fragrance ingredient. It can be produced naturally by fermenting castor-oil-derived fatty acids, or made synthetically from petrochemical building blocks; both routes are used in the fragrance industry.
