How we scored it
AlHO2 59.99 Da: aluminium, oxide and hydroxide all mineral-derived (bauxite): 59.99 / 59.99 = 1.00.
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
Dominant route is Bayer-process refining of bauxite ore into alumina hydrates, including boehmite. Precipitated grades also start from aluminium from bauxite, so there is no petrochemical alternative.
In plain English
A white mineral powder (boehmite) made from bauxite ore. It is listed in cosmetic ingredient databases for astringent, skin-protecting, skin-conditioning and antimicrobial roles.
Structure
hydroxy(oxo)alumane
