How we scored it
Steam-distillate water (n=1) plus trace plant volatiles (n=1); no synthetic fragment. 1.00 / 1.00 = 1.00.
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
Edelweiss flowers and leaves are steam-distilled and the condensed aqueous phase is collected. No synthetic route exists; any preservative added to the water is declared separately.
In plain English
A water made by steam-distilling edelweiss (Leontopodium alpinum) flowers and leaves and collecting the condensed liquid. CosIng lists it as an emollient, humectant and skin-conditioning ingredient. It is mostly water with traces of the plant's aromatic compounds.
CosIng definition: Leontopodium Alpinum Flower/Leaf Water is the aqueous solution of the steam distillates derived from the flowers and leaves of Leontopodium alpinum. The accepted scientific name for Leontopodium alpinum is Leontopodium nivale.
