How we scored it
INCI is the whole steam-distilled leaf oil (botanical essential oil, =1.0); attached formula/iupac correspond to methyl salicylate, the oil's dominant natural constituent (~98%), not a separate synthetic entry.
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
Produced by steam-distilling Gaultheria procumbens leaves; the oil is naturally rich in methyl salicylate. This INCI entry denotes the natural essential oil, distinct from synthetic methyl salicylate.
In plain English
The essential oil steam-distilled from wintergreen leaves, used mainly as a fragrance ingredient. It is naturally rich in methyl salicylate, the compound responsible for its characteristic minty, medicinal scent.
CosIng definition: Gaultheria Procumbens Leaf Oil is the volatile oil obtained from the leaves of the Wintergreen, Gaultheria procumbens L., Ericaceae
