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.

RouteFeedstockNOIShareNotes
synthetic petrochemicalpetrochemical building blocks0.00~60-70%
natural fermentationcastor oil ricinoleic acid1.00~30-40%
Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

Natural route: fermented/biotransformed from castor-oil ricinoleic acid = 1.0. Synthetic route: built from petrochemical feedstocks = 0.0
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

Produced either by fermenting or biotransforming castor-oil-derived ricinoleic acid, marketed as natural, or by total chemical synthesis from petrochemical feedstocks; the synthetic route dominates bulk fragrance supply on cost.

In plain English

A creamy, peach- or coconut-like fragrance and flavour ingredient, produced either by fermenting castor oil or by chemical synthesis from petrochemical feedstocks.
