How we scored it

Magnesium + silicate, both mineral-derived, natural origin = 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 trisilicate is derived from natural silicate minerals combined with magnesium. It is mined and processed from mineral ores rather than synthesised from petrochemicals.

In plain English

A mineral (magnesium silicate) used as an absorbent, anti-caking, bulking and opacifying ingredient, for example in powders.
