How we scored it
C10H12O; principal component of anise/star anise oil, overwhelmingly isolated by crystallisation directly from the cheap natural essential oil rather than synthesised => 1.0
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
Anethole is obtained mainly by chilling and crystallising it directly out of natural star anise or anise essential oil, which is cheap and abundant. A synthetic petrochemical route exists but is a minor share of commercial supply.
In plain English
A sweet, licorice-like fragrance and flavour ingredient, the main component of anise and star anise oil. It is typically isolated directly from these plant oils rather than made synthetically.
Structure
1-methoxy-4-[(E)-prop-1-enyl]benzene
