How we scored it

Allyl fragment C3H5O (57 Da, petrochemical from propylene) + hexanoyl fragment C6H11O (99 Da, natural coconut/palm-kernel caproic acid). 99/156 = 0.63.
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

Allyl caproate is made by esterifying allyl alcohol, made from petrochemical propylene, with caproic (hexanoic) acid typically fractionated from coconut or palm kernel oil. The acid portion is natural; the alcohol portion is synthetic.

In plain English

A fruity, pineapple-scented fragrance ingredient. It combines a lab-made alcohol with a fatty acid typically derived from coconut or palm kernel oil, so it is partly plant-based and partly synthetic.
