Is Aluminum Zirconium Trichlorohydrex Gly natural?

It depends. An antiperspirant salt that is almost entirely mineral; the small glycine buffer decides whether it is fully natural origin.

INCI nameAluminum Zirconium Trichlorohydrex Gly
CAS134375-99-8
FormulaC2H8AlClNO4Zr+5 · 263.74 Da
FunctionAntiperspirant · Astringent
FeedstockAluminium and zirconium chlorohydrate minerals complexed with glycine.

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.

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)13Cl3.xH2O reacted with glycine (about one glycine per zirconium). The inorganic part 634.5 Da is entirely mineral (natural origin); glycine 75.1 Da is route-dependent on this site: 1.0 with natural glycine, 634.5/709.6 = 0.89 with synthetic glycine.
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 chlorohydrate minerals complexed with glycine.

In plain English

An antiperspirant active made from aluminum and zirconium minerals combined with glycine, an amino acid. It works by temporarily reducing underarm wetness.

CosIng definition: Complex reaction product obtained from the reaction of aluminium zirconium trichlorohydrate (Al8Zr(OH)13Cl3.xH2O) with glycine
