How we scored it

Nitrophenol with hydroxyethylamino side chain (from ethylene oxide); phenol and ethylene oxide both petrochemical → 0.0.
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

This hair-dye intermediate is synthesized from a nitrophenol core reacted with ethylene-oxide/ethanolamine chemistry. No natural production route exists.

In plain English

A synthetic hair-dye ingredient combining a phenol core with a side chain derived from ethylene oxide. It is entirely petrochemical in origin.
