How we scored it

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

Cedrol isolated from cedarwood oil is methylated with a methylating agent such as dimethyl sulfate or methyl chloride. No significant alternative route exists, and the methyl cap is the only non-natural group.

In plain English

A woody, ambery fragrance ingredient. It is made by converting cedrol, an alcohol found in cedarwood oil, into its methyl ether.
