How we scored it
Potassium (mineral) and silicate (mineral, silica-derived), both natural-origin. 214/214 = 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
Potassium silicate is an inorganic mineral salt formed from potassium and silica. It is classed as natural/mineral origin under ISO 16128.
In plain English
A mineral salt used to prevent corrosion in a formula. It is made from potassium and silica, both naturally occurring mineral elements.
