How we scored it
Mineral sodium silicate (silica + sodium, both natural-origin minerals) = 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
Manufactured by fusing natural silica sand with sodium carbonate at high temperature. No alternative petrochemical route exists; both starting minerals are natural.
In plain English
A mineral compound used to buffer pH and prevent corrosion in formulas. It's made by fusing sand with soda ash, both mineral, natural-origin materials.
Structure
disodium;dioxido(oxo)silane
