Is Sodium Acetylated Hyaluronate natural?

Mostly. The hyaluronate backbone is a natural fermentation polymer; the added O-acetyl groups are treated as a petrochemical cap.

INCI nameSodium Acetylated Hyaluronate
FunctionHumectant
FeedstockFermentation-derived sodium hyaluronate is chemically O-acetylated (using acetic…

How we scored it

Assumes ~1 added O-acetyl group per disaccharide repeat unit (typical DS): natural hyaluronate repeat 401Da + petrochemical acetyl cap 42Da = 401/443 = 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

Fermentation-derived sodium hyaluronate is chemically O-acetylated (using acetic anhydride) to improve film-forming and substantivity. Exact degree of substitution varies by supplier.

In plain English

A modified form of hyaluronic acid with small chemical caps added so it forms a longer-lasting film on skin. The base molecule comes from fermentation; the added groups are lab-made.
