How we scored it

Metal oxide mineral, analogous to titanium dioxide/zinc oxide -> 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

Produced by oxidising mined tin ore (cassiterite) or refined tin metal. No organic synthetic route is used.

In plain English

A mineral powder used to add bulk, texture and mild abrasion in powders and pastes. It is derived from mined tin ore.
