Is Ascorbyl Methylsilanol Pectinate natural?

Mostly. Fermentation-derived ascorbic acid and fruit-derived pectin dominate the mass; the silicone-convention methylsilanol crosslinker is a small stoichiometric fraction.

How we scored it

Ascorbic acid (natural, fermentation) + pectin backbone (natural, fruit polysaccharide, bulk of mass) + methylsilanetriol (0.0, silicone convention, minor crosslinker) → estimated 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 reacting ascorbic acid and plant pectin with methylsilanetriol, a silicon crosslinker treated as petrochemical by this site's convention. Exact substitution ratio is not publicly specified.

In plain English

An antioxidant, thickening ingredient combining vitamin C and plant pectin with a small amount of a silicon-based crosslinker. Used in skincare for antioxidant and texture-building properties.
