Is Laurdimonium Hydroxypropyl Hydrolyzed Soy Protein natural?

Mostly. Most of the molecule is fermentation/hydrolysis-derived soy protein and a natural coconut-derived lauryl chain; only the small hydroxypropyl-trimethylammonium quaternizing linker is petrochemical.

How we scored it

Soy protein hydrolysate (~800 Da natural) + lauryl C12H25 (169 Da natural) + chloride (35 Da natural) vs hydroxypropyl-N(CH3)2+ quaternary linker (~100 Da petrochemical, from propylene oxide/methyl chloride): ~1004/1104 = 0.90.
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

Made by quaternizing hydrolyzed soy protein with a lauryl dimethyl quaternary ammonium epoxide reagent. The protein and lauryl portions are plant-derived; the hydroxypropyl linker comes from propylene oxide.

In plain English

A conditioning ingredient used in shampoos and hair products to reduce static and improve feel. It is made from soy protein that has been broken down and combined with a coconut-derived fatty part and a small lab-made linking group.
