How we scored it
MgO.SiO2 mineral silicate (talc-type); magnesium and silica both natural mineral feedstocks => 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 Silicate is produced by processing natural talc-type silicate mineral ore. It is used essentially as mined and purified, with no petrochemical alternative.
In plain English
A mineral powder related to talc, used to absorb oil, prevent caking, add bulk, and control thickness in powders and other formulas. It comes from naturally occurring magnesium and silica minerals.
Structure
magnesium;tris(oxygen(2-));silicon(4+)
