How we scored it

Al/OH/Cl inorganic complex salt; all mineral fragments 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

Made by reacting mined aluminium hydroxide/metal with hydrochloric acid to form a soluble chlorohydrate salt. No organic or petrochemical fragment is present.

In plain English
