Is Methylsilanol Elastinate natural?

Mostly. Natural elastin protein backbone dominates the mass; small petrochemical silicone grafts reduce the index slightly.

INCI nameMethylsilanol Elastinate
FunctionAntistatic · Skin Conditioning
FeedstockMade by reacting hydrolysed animal-derived elastin protein with…

How we scored it

Hydrolysed elastin (natural protein, majority of mass) esterified with methylsilanol siloxane (non-natural); estimated 85% natural, substitution degree undisclosed.
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 hydrolysed animal-derived elastin protein with a hydroxy-terminated methyl siloxane. The exact substitution ratio is not disclosed by suppliers.

In plain English

A conditioning ingredient combining elastin protein from animal connective tissue with a small silicone, used to soften and smooth skin and hair.

CosIng definition: Elastins, esters with hydroxy-terminated hydroxy Me siloxanes
