How we scored it
Al/Zr/Cl/OH mineral complex (natural) + glycine (amino acid, natural); all 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 and zirconium mineral salts (chlorohydrate complexes) with glycine. Glycine is usually treated as a fermentation/hydrolysate amino acid, though a petrochemical synthetic route for glycine also exists industrially.
In plain English
The active ingredient in many antiperspirants, used to reduce underarm wetness and odour. Made by reacting mined aluminium and zirconium mineral salts with glycine, a simple amino acid.
CosIng definition: Complex reaction products obtained from the reaction of aluminium zirconium tetrachlorohydrate (Al8Zr(OH)12Cl4.xH2O) and glycine
