Is Hydrolyzed Pea Protein PG-Propyl Silanetriol natural?

Mostly. Pea protein hydrolysate is plant-derived; the glycidyl-propyl-glycol chain comes from petrochemical feedstocks and the silanetriol is organosilicon, scored 0 under the site silicone convention.

How we scored it

Pea hydrolysate ~1,000 Da (n=1) + PG-propylsilanetriol C6H14O5Si 194 Da (n=0: petrochemical C6 chain, Si by silicone convention). Assumed 1 group per 1,000 Da: 1000/1194 = 0.84.
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

Dominant route reacts hydrolysed pea protein with a glycidoxypropyl silane (hydrolysed to the silanetriol), whose epoxide binds to amine groups on the peptides. The degree of substitution is not published, so 1 group per 1,000 Da is an assumption.

In plain English

A conditioning ingredient for hair and skin made by attaching a small silicon-containing group to broken-down pea protein. The protein part comes from peas; the silicon-propyl-glycol group is made industrially. It is used for hair and skin conditioning.
