How we scored it

ACH Al2Cl(OH)5 174.4 Da (mineral, natural) + propylene glycol C3H8O2 76.1 Da (petrochemical), ~1:1 complex assumed -> 174.4/250.5 = 0.70
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

Aluminum chlorohydrate is manufactured from bauxite-derived aluminum reacted with chlorine, a mineral-origin process. It is complexed with propylene glycol, a petrochemical propylene-oxide derivative, to improve solubility.

In plain English

Reduces underarm wetness and odor in antiperspirants and deodorants. It combines a mineral aluminum salt with propylene glycol, a petrochemical solvent that helps it dissolve and spread evenly on skin.
