Is Hydrolyzed Vegetable Protein PG-Propyl Silanetriol natural?

Mostly. A natural protein hydrolysate grafted with a small organosilicon group. The peptide is natural; the silanetriol graft follows the site's organosilicon convention. Same approach as Sodium Hyaluronate Dimethylsilanol.

INCI nameHydrolyzed Vegetable Protein PG-Propyl Silanetriol
FunctionHair Conditioning · Skin Conditioning
FeedstockProtein hydrolysate reacted with glycidoxypropyl silanetriol.

How we scored it

Per ~1,000 Da of peptide (natural protein hydrolysate) one PG-propyl silanetriol group C6H15O5Si 195.3 Da (organosilicon, 0.0 by this site's convention); 1000/1195.3 = 0.84. Substitution level is supplier-dependent; the same model is used for all four silanetriol proteins 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 glycidoxypropyl silanetriol.

In plain English

A plant-protein hydrolysate that has been chemically modified with a small silicone-like (silanetriol) group. Used in hair and skin products for conditioning and to help products spread and adhere evenly.

CosIng definition: Proteins, vegetable, hydrolysed, 2-hydroxy-3-(3-(trihydroxysilyl)propoxy)propyl derivatives
