How we scored it
Elemental aluminum metal, no other atoms present; Al is an explicitly listed natural-origin mineral element, so fraction = 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
Aluminum powder is produced by refining bauxite ore into alumina and then reducing it to metallic aluminum, which is milled into powder. It contains no other added materials.
In plain English
Finely powdered aluminum metal used to add shimmer or color to cosmetics. It comes from refining bauxite ore, a naturally occurring mineral, into pure aluminum metal.
CosIng definition: Aluminum Powder is a metallic element composed of finely divided particles of aluminum free of other added materials. To identify the colorant allowed for use in the European Union (EU), the INCI Name CI 77000 must be used.
