How we scored it

Pentasodium salt of DTPA; same fully synthetic diethylenetriamine + chloroacetate backbone as Pentetic Acid, sodium doesn't change the carbon skeleton's origin.
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 pentasodium salt of DTPA (pentetic acid), made from diethylenetriamine and monochloroacetic acid, both petrochemical. Sodium hydroxide is used only to neutralize the acid form.

In plain English

A synthetic chelating agent, the salt form of a common water-softening, metal-binding ingredient that protects formulas from trace metals. Built entirely from petroleum-derived chemical building blocks.

CosIng definition: Pentasodium Pentetate is the pentasodium salt of diethylenetriaminepentaacetic acid. It conforms to the formula:
