How we scored it
Steam-distillate water (n=1) plus dissolved volatiles of Cupressus sempervirens leaf (n=1); no synthetic atoms: 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 route: steam distillation of cypress (Cupressus sempervirens) leaves, with the aqueous condensate collected as the hydrosol. No alternative route is commercially significant.
In plain English
A cypress hydrosol: the water collected when cypress leaves are steam-distilled, carrying traces of the tree's aromatic compounds. Used as a skin-conditioning water phase in toners and lotions.
CosIng definition: Cupressus Sempervirens Leaf Water is an aqueous solution of the steam distillate obtained from the leaves of the Cypress, Cupressus sempervirens L., Cupressaceae
