Sclareol has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Sclareol is extracted from clary sage plant material, not commercially synthesised from petrochemical feedstock. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

Is Sclareol natural? NOI 1.00

How we scored it

Diterpene diol isolated directly from clary sage concrete/absolute by extraction; no commercial synthetic route. 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

Isolated by solvent extraction and purification from clary sage, Salvia sclarea. It is also a precursor for semi-synthetic ambroxide, but sclareol itself is plant-extracted with no petrochemical route.

In plain English

A natural fragrance and fixative ingredient with an amber, musky scent, extracted from clary sage plants. It's also used as a starting material to make other perfume ingredients.
