How we scored it
Steam-distillate water (n=1) plus dissolved volatiles of Avena sativa seed (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 oat (Avena sativa) seeds, with the aqueous condensate collected as the hydrosol. No alternative route is commercially significant.
In plain English
An oat hydrosol: the water collected when oat seeds are steam-distilled, used as a water-based solvent in skin and hair products. It carries only traces of the plant's volatile compounds.
CosIng definition: Avena Sativa Seed Water is an aqueous solution of the steam distillates obtained from the seeds of Avena sativa.
