Is Aluminum Zirconium Pentachlorohydrex Gly natural?

It depends. Antiperspirant salt: an aluminium-zirconium chlorohydrate buffered with glycine. The mineral part is natural in every case; the small glycine share follows the glycine route, which this site treats as route-dependent.

Why the score varies

This ingredient is made commercially by more than one route, and ISO 16128 scores the feedstock actually used. Without a supplier certificate of origin the value cannot be claimed.

RouteFeedstockNOIShareNotes
fermentation or hydrolysate glycineAl8Zr(OH)15Cl5 chlorohydrate complexed with natural glycine1.00Mineral complex plus a natural amino acid.
synthetic glycineAl8Zr(OH)15Cl5 chlorohydrate complexed with Strecker/chloroacetic-acid glycine0.91Only the inorganic part counts: 739.4/814.5 = 0.91.
Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

Per CosIng the complex is Al8Zr(OH)15Cl5 with about one glycine per zirconium. Inorganic part 8 Al + Zr + 15 OH + 5 Cl = 739.4 Da is entirely mineral (natural); glycine 75.1 Da is natural from fermentation or protein hydrolysate (NOI 1.00) and petrochemical from chemical synthesis (739.4/814.5 = 0.91). Same method as Aluminum Zirconium Octachlorohydrex Gly.
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

Aluminium and zirconium chlorohydrates from mineral aluminium, zirconium and hydrochloric acid, complexed with glycine.

In plain English

An antiperspirant active made from aluminium and zirconium mineral salts combined with the amino acid glycine, used to reduce underarm wetness.

CosIng definition: Complex reaction product obtained from the reaction of aluminium zirconium pentachlorohydrate (Al8Zr(OH)23Cl5.xH2O) and glycine
