Is CI 40825 natural?

It depends. Industrial apocarotenoid colorants are usually built from petrochemical C15 units via Wittig chemistry; natural carotenoid extraction is a minor alternative feedstock.

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
Total chemical synthesis (Wittig-type)petrochemical isoprenoid building blocks0.00~90%, dominant
Extraction/fermentation-derived carotenoid, esterifiedpalm/algal carotenoid + bioethanol1.00~10%, minor
Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

As the ethyl ester of an apocarotenoic acid: total-synthesis route from petrochemical isoprenoid units gives 0.0 (dominant); a minor route esterifies extracted/fermented carotenoid with bioethanol, giving 1.0. Not averaged. Headline shows the best route (1.00), as for every route-dependent entry on the site.
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

CI 40825 is typically produced by total chemical synthesis from petrochemical intermediates. A minor natural route exists using carotenoids extracted or fermented from plant/algal sources and esterified with ethanol.

In plain English

A carotenoid-type colour additive giving orange shades to cosmetics; usually made by chemical synthesis, occasionally from natural carotenoid sources.

CosIng definition: CI 40825 is classed chemically as a carotenoid colour. It conforms to the formula:
