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.

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: fermentation from natural fat/dairy precursors = 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 fermentation from natural fat or dairy sources, marketed as natural, or by total chemical synthesis from petrochemical feedstocks; synthetic supply dominates the bulk market.

In plain English

A coconut- or fruity-scented fragrance ingredient, produced either by natural fermentation or by chemical synthesis from petrochemical feedstocks.
