How we scored it
Entirely inorganic: aluminum, zirconium, chloride and hydroxide groups; all mineral (metal ions, hydroxide, chloride); no carbon or petrochemical atoms present in the formula.
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 to form the hydroxychloride complex. No organic or petrochemical alternative route applies to this inorganic salt.
In plain English
The active ingredient in many antiperspirants that temporarily reduces sweat. It is an inorganic mineral salt made from aluminum and zirconium, not derived from plants or petroleum.
