Is Pentetic Acid natural?

No. Both the triamine backbone and the five acetic-acid arms come from petrochemical ethyleneamine and chloroacetic acid.

How we scored it

DTPA: diethylenetriamine (petrochemical) + 5x chloroacetate arms (petrochemical) -> fully synthetic chelator, no natural fragment.
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

Synthesized from diethylenetriamine and monochloroacetic acid, both petrochemical intermediates from ethylene and chlorine chemistry. No natural-origin production route is used commercially.

In plain English

A synthetic chelating agent that locks onto trace metal ions in a formula to stop them degrading fragrance or causing discoloration. Made entirely from petroleum-derived chemical building blocks.

CosIng definition: Pentetic Acid is the substituted amine that conforms to the formula:
