Is Pentaerythrityl Tetraisononanoate natural?

No. Pentaerythritol comes from formaldehyde and acetaldehyde and branched isononanoic acid from petrochemical oxo chemistry, so no natural fragment is present.

How we scored it

C41H76O8, 697 Da: pentaerythritol core (formaldehyde plus acetaldehyde) and four branched isononanoyl chains (oxo chemistry) are all petrochemical. 0 / 697 = 0.00.
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

Pentaerythritol is esterified with isononanoic acid made by hydroformylation of petrochemical octenes. No natural route is commercial.

In plain English

A light, non-greasy synthetic ester used as an emollient. It spreads easily, gives a dry, silky feel and helps dissolve other oils and pigments in makeup, sunscreen and skincare.
