Is Hydroxypropyltrimonium Hydrolyzed Wheat Protein natural?

Mostly. Peptide backbone traces to hydrolysed wheat protein; the hydroxypropyltrimethylammonium group traces to propylene oxide and methanol/methylamine feedstocks.

How we scored it

Assume ~1000 Da average peptide (natural) plus one quat site: hydroxypropyltrimethylammonium addition (~130 Da, petrochemical) + Cl (35, natural). Natural (1000+35)/1165 = 0.89.
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

Hydrolysed wheat protein is quaternised with a trimethylammonium hydroxypropyl group (no fatty chain), derived from propylene-oxide-based glycidyl trimethylammonium chloride. The protein backbone still dominates the molecule's mass, keeping natural-origin content high.

In plain English

A conditioning ingredient made from hydrolyzed wheat protein modified with a small synthetic linker so it binds better to hair and skin. Mostly protein-derived, with a lab-made attachment.
