Is Isobornyl Acetate natural?

Mostly. Isoborneol fragment derives from alpha-pinene/camphene in pine turpentine; the acetate comes from petrochemical acetic anhydride.

How we scored it

Isoborneol C10H18O (154.3) minus H = 153.2 natural, pine-terpene derived; acetate C2H3O (43.0) petrochemical; 153.2/196.3=0.78.
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.

How it’s made

Camphene adds acetic acid (acid-catalysed: protonation, Wagner–Meerwein shift, acetate capture). Each curved arrow moves one electron pair, and the film ends on the score above.

Where it comes from

Made by acetylating isoborneol, which is produced from camphene derived from natural pine turpentine (alpha-pinene). The acetyl group comes from petrochemical acetic anhydride.

In plain English

A pine-scented fragrance ester made by combining a pine-derived terpene alcohol with acetic acid; used to add scent to cosmetic products.
