How we scored it

Assumed Al2Cl1.5(OH)4.5 core 184Da(1, mineral)+PEG modifier ~80Da(0, minor est. stoichiometry) -> 184/264=0.70 (PEG chain length/ratio not specified).
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

An inorganic aluminum chlorohydrate core reacted with a small proportion of polyethylene glycol. Exact PEG chain length and ratio are not specified by supplier data.

In plain English

An antiperspirant active combining a mineral aluminum salt with a small amount of polyethylene glycol. Most of the ingredient is mineral in origin, with a minor synthetic component.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-hydroxy-, reaction products with aluminium chloride hydroxide (Al2Cl1.5(OH)4.5)
