How we scored it
Entirely inorganic: aluminum, zirconium, chloride and hydroxide groups (one fewer Cl, one more OH than the tetrachlorohydrate); all mineral; no organic or petrochemical atoms.
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
Manufactured from mined aluminum and zirconium sources reacted with hydrochloric acid. No organic or petrochemical alternative route applies to this inorganic antiperspirant salt.
In plain English
An antiperspirant active very similar to aluminum zirconium tetrachlorohydrate, with a slightly different ratio of chloride to hydroxide. It is an inorganic mineral salt, not plant- or petroleum-derived.
Structure
tetraaluminum;zirconium(4+);trichloride;tridecahydroxide
