How we scored it

Isoborneol (from pine turpentine camphene, natural, no carbon lost) 153.2 Da + propionyl (petrochemical) 57.1 Da = 153.2/210.3 = 0.73
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

Isoborneol is manufactured from alpha-pinene in pine turpentine via camphene; this is esterified with petrochemical propionic acid.

In plain English

A fragrance ingredient with a woody, pine-like smell, made by combining a pine-tree-derived terpene alcohol with propionic acid. Used purely for scent.
