How we scored it
Water (n = 1) holding traces of steam-distilled rosemary volatiles (n = 1); nothing synthetic. Natural mass / total mass = 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
Dominant feedstock is rosemary (Rosmarinus officinalis) flowers, leaves and stems, steam-distilled; the aqueous distillate (hydrosol) is a by-product of essential-oil production. No synthetic route exists for the hydrosol.
In plain English
The water collected when rosemary flowers, leaves and stems are steam-distilled, carrying traces of rosemary's aroma compounds. It is used in products as a water-based ingredient with a fragrance role. It comes from the rosemary plant, often as a by-product of making rosemary essential oil.
