Is Silanetriol natural?

How we scored it

Methylsilanetriol CH3Si(OH)3, 94.1 Da: organosilicon with a silicon-carbon bond → 0.0 by this site's convention. Mineral silica and silicates keep their mass; organosilicons do not.
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

Methyltrichlorosilane (from silicon metal and petrochemical methyl chloride) hydrolysed in water.

In plain English

A silicon-based conditioning ingredient for hair, formed from mineral silicon with one small methyl group attached. Mostly derived from mineral silica, with a small part from a synthetic chemical step.
