Is Hydroxypropyltrimonium Hydrolyzed Conchiolin Protein natural?

Mostly. A natural protein hydrolysate carrying a small number of quaternary ammonium groups. The peptide, any fatty chain and the chloride are natural; the methylated nitrogen and the hydroxypropyl linker are petrochemical.

How we scored it

Per ~1,000 Da of peptide (natural protein hydrolysate) one quaternary group: chloride 35.5 Da (mineral) natural; N + 3×CH3 59.1 Da and hydroxypropyl C3H6O 58.1 Da petrochemical; 1035.5/1152.6 = 0.90. Substitution level is supplier-dependent; the same model is used for every quaternised protein in this wave.
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

Protein hydrolysate reacted with a glycidyl or chlorohydroxypropyl quaternary ammonium reagent.

In plain English

A protein from mollusc shell or pearl material, broken into smaller pieces and given a mild, permanent electrical charge so it clings to hair and skin. Used as a conditioning ingredient.

CosIng definition: 1-Propanaminium, 2-hydroxy-N,N,N-trimethyl-, 3-(conchiolin protein hydrolyzates) derivs., chloride
