How we scored it

Natural aluminum/magnesium silicate clay mineral, explicitly natural origin = 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

Mined from volcanic-ash-derived clay deposits (bentonite ore) and processed by grinding/purification. No synthetic route is used.

In plain English

A natural clay mineral that absorbs oil and adds bulk or stabilising texture to masks and powders. Mined from volcanic-ash clay deposits.
