Is Potassium Tartrate natural? NOI 1.00

Q: Is Potassium Tartrate natural?

Potassium Tartrate has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Tartaric acid is an overwhelmingly natural grape-derived fruit acid with no significant petrochemical route; potassium is a natural mineral ion. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Tartaric acid (grape/winemaking byproduct, natural) + potassium (mineral counter-ion, natural) → 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

Obtained by neutralizing tartaric acid (recovered from wine-industry calcium-tartrate/argol byproduct) with a potassium base. No petrochemical synthesis route is used commercially.

In plain English

The potassium salt of grape-derived tartaric acid, used as a buffering agent to help stabilise a formula's pH.
