How we scored it
Al2MgO4 142.3: Al 54.0 + Mg 24.3 + O4 64.0, all mineral: 142.3 / 142.3 = 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
Magnesium aluminate spinel is produced by high-temperature calcination of aluminium and magnesium oxides or hydroxides from bauxite and magnesite or seawater magnesia. It also occurs naturally as the mineral spinel.
In plain English
A mineral powder (magnesium aluminate spinel) used to absorb oil and moisture, stop powders caking and add bulk, including in oral-care products. It is made from aluminium and magnesium oxides of mineral origin.
