How we scored it

Three hydroxypropyl groups on ammonia, all from propylene oxide; petrochemical, the propylene-oxide analog of the explicitly-listed triethanolamine.
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

Manufactured by reacting propylene oxide with ammonia to add three hydroxypropyl groups. Structurally the propylene-oxide analog of triethanolamine, which this site's method treats as petrochemical.

In plain English

A synthetic pH-buffering ingredient made entirely from petroleum-derived propylene oxide and ammonia. Helps keep a formula's acidity in the right range.
