How we scored it
Horehound flower, leaf and stem extract: every constituent is plant-derived (n=1); extraction solvent leaves no mass. 1.0 x 100% = 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
Dominant feedstock is the dried aerial parts of Marrubium vulgare extracted with water or water-alcohol. No alternative route exists; any carrier solvent is declared as its own ingredient.
In plain English
An extract of the flowers, leaves and stems of white horehound, a mint-family herb, made by soaking the plant in a solvent. It is listed as a fragrance ingredient. It comes entirely from the plant.
CosIng definition: Marrubium Vulgare Flower/Leaf/Stem Extract is the extract of the flowers, leaves and stems of Marrubium vulgare, Lamiaceae.
