Is Dimethicone Silylate natural?

Mostly not. The silicone fluid is not credited by this site's convention, while the silica filler is mineral and counts as natural origin; the silica share is an assumed typical grade.

INCI nameDimethicone Silylate
FunctionAntifoaming
FeedstockDominant route: polydimethylsiloxane (silicon metal plus methyl chloride)…

How we scored it

Dimethicone fluid ~92% (silicone, 0.0 by this site's convention) + silylated silica filler ~8% (mineral, 1.0; assumed typical antifoam grade): 0.92 x 0 + 0.08 x 1 = 0.08.
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: polydimethylsiloxane (silicon metal plus methyl chloride) compounded with hydrophobic silica (from sand) whose surface carries trimethylsilyl groups. The silica fraction varies by grade, so the value is an estimate.

In plain English

A silicone antifoam: a silicone oil mixed with fine, water-repellent silica that breaks foam bubbles. It is mostly synthetic silicone with a small mineral silica part.

CosIng definition: Silicones and siloxanes, dimethyl, reaction products with silica and trimethylsilane
