Is Dipotassium EDTA natural?

Mostly not. The EDTA backbone is petrochemical (ethylenediamine-based); only the potassium counter-ions are natural mineral mass.

INCI nameDipotassium EDTA
CAS2001-94-7
FormulaC10H14K2N2O8 · 368.42 Da
FunctionChelating
FeedstockThe EDTA core is synthesised from petrochemical ethylenediamine…

How we scored it

K2 (78.20 Da, mineral, natural) + synthetic EDTA backbone C10H14N2O8 (290.22 Da, petrochemical) → 78.20/368.42 = 0.21.
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

The EDTA core is synthesised from petrochemical ethylenediamine and chloroacetic acid/formaldehyde-cyanide, then neutralised with potassium hydroxide. No natural route exists for the organic backbone.

In plain English

A chelating ingredient that traps trace metal ions to keep a formula stable. Made from the synthetic molecule EDTA combined with potassium; the core molecule is lab-made, not plant-derived.
