Is Laurdimonium Hydroxypropyl Hydrolyzed Wheat Protein natural?

Mostly. The wheat protein hydrolysate backbone and the coconut or palm-derived lauryl group are natural. Only the dimethyl groups and the hydroxypropyl linker atoms are petrochemical.

How we scored it

Assuming an 1100 Da wheat peptide with one lauryl-dimethyl-hydroxypropylammonium cap of about 270 Da: natural origin is the peptide (1100 Da) plus the lauryl chain C12H25 (169 Da) = 1269 Da, against a petrochemical dimethyl and hydroxypropyl portion of about 102 Da. Total 1371 Da, so 1269/1371 = 0.93.
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

Wheat gluten is hydrolysed into peptides, then reacted with a lauryl dimethyl quaternary ammonium reagent made partly from coconut or palm fatty alcohol and partly from epichlorohydrin. The degree of substitution is not published and was assumed low.

In plain English

A conditioning ingredient for hair and skin made from wheat protein broken into smaller pieces and given a mild positive charge using a coconut- or palm-derived fatty group, helping it cling to hair.
