How we scored it
Hydrosol: water (n = 1) plus trace volatile plant terpenoids and alcohols from the steam distillate (n = 1). No other atoms. 1.0 / 1.0 = 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 is steam distillation of Capsella bursa-pastoris sprouts, collecting the aqueous condensate as a hydrosol. No commercially significant alternative route exists.
In plain English
The water collected when sprouts of shepherd's purse (Capsella bursa-pastoris), a common weed of the cabbage family, are steam-distilled. It is mostly water with traces of the plant's volatile compounds and is listed as an antioxidant and skin-protecting ingredient.
CosIng definition: Capsella Bursa-Pastoris Sprout Water is the aqueous solution of the steam distillates obtained from the sprouts of the Shepherd's Purse, Capsella bursa-pastoris (L.), Brassicaceae
