How we scored it

Beta-apo-8'-carotenal C30H40O: commercial supply is essentially all total synthesis (Wittig route from petrochemical ionone/aldehyde fragments); no significant natural-extraction supply chain → 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

Beta-apo-8'-carotenal is manufactured by total chemical synthesis from petrochemical aldehyde and phosphonium intermediates. Natural extraction is not a commercially significant source for this specific colourant.

In plain English

A synthetic orange carotenoid-type colourant related to beta-carotene, used to tint cosmetic products. Commercial supply is essentially all made by chemical synthesis rather than extracted from plants.

CosIng definition: CI 40820 is classed chemically as a carotenoid colour. It conforms to the formula:
