How we scored it

Polymer of 1,4-dichlorobutene (petrochemical) with dimethylamine and triethanolamine quaternary end groups (synthetic amine) => 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

Polyquaternium-1 is produced by polymerising 1,4-dichloro-2-butene with dimethylamine and end-capping with triethanolamine, all petrochemical building blocks. No natural-origin route exists for this synthetic polymer.

In plain English

A film-forming polymer used in products like contact lens solutions and hair styling formulas. It's built entirely from synthetic building blocks, including a chlorinated butene and modified ethanolamine.
