How we scored it
Steam-distillate water (n=1) plus dissolved volatiles of Thymus vulgaris leaf and stem (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 thyme (Thymus vulgaris) leaves and stems, with the aqueous condensate collected as the hydrosol. No alternative route is commercially significant.
In plain English
A thyme hydrosol: the water collected when thyme leaves and stems are steam-distilled, carrying traces of the plant's aromatic compounds. Used as a skin-conditioning water phase in toners and lotions.
CosIng definition: Thymus Vulgaris Leaf/Stem Water is the aqueous solution of the steam distillate obtained from the leaves and stems of Thymus vulgaris (Lamiaceae).
