How we scored it
Steam distillate of kelp condensed in water — botanical hydrosol, no synthetic input — 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
Produced by steam-distilling fresh giant kelp (Macrocystis pyrifera) and condensing the aromatic water fraction. No alternative route.
In plain English
A water-based distillate made from giant kelp seaweed, used in skincare to condition and soothe skin with marine-derived compounds.
