Is Polyquaternium-59 natural?

No. PEG/polyether backbone traces to ethylene oxide; hydroxypropyl linker traces to propylene oxide; the phenyl-propenamido group traces to petrochemical cinnamic-acid synthesis.

How we scored it

PEG-type polyether/quaternary-ammonium backbone (hexaoxapentacosanediyl chain) with a hydroxypropyl linker and a phenyl (cinnamamide) UV-absorbing group; every identifiable fragment is 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

A PEG-based quaternary-ammonium polymer bearing a cinnamic-acid-amide UV-absorbing group, built from ethylene oxide, propylene oxide and synthetic aromatic chemistry. No natural or mineral fragment is present in the structure.

In plain English

A synthetic conditioning polymer that also helps absorb UV light, built from a polyethylene-glycol-type backbone with an aromatic group attached. Entirely lab-made from petrochemical building blocks.
