Is Potassium Fluorosilicate natural?

Q: Is Potassium Fluorosilicate natural?

Potassium Fluorosilicate has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Potassium, silicon and fluoride are all mineral-derived fragments, not an organosilicon silicone, so natural origin applies. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

Yes. Potassium, silicon and fluoride are all mineral-derived fragments, not an organosilicon silicone, so natural origin applies.

INCI namePotassium Fluorosilicate

CAS16871-90-2

FeedstockProduced from mineral silica/fluorosilicic acid neutralized with potassium…

How we scored it

K2SiF6 — inorganic mineral salt (potassium, silicon, fluoride all 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

Produced from mineral silica/fluorosilicic acid neutralized with potassium salts. No petrochemical route applies to this inorganic salt.

In plain English

An inorganic mineral salt of potassium, silicon and fluoride, occasionally used as a functional additive in formulas.
