How we scored it
Steam distillate of strawberry-tree leaves: water (1) plus trace plant volatiles (1). 1.0 / 1.0 = 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
Leaves of the strawberry tree (Arbutus unedo), a Mediterranean shrub, are steam-distilled and the aqueous distillate (hydrosol) is collected. No commercially significant alternative route.
In plain English
A water-based distillate collected when leaves of the strawberry tree, Arbutus unedo, are steamed. It is mostly water carrying trace plant compounds and is used in products as an emollient and skin-conditioning ingredient.
