Is Bis-Ethylhexyl Hydroxydimethoxy Benzylmalonate natural?

No. 2-Ethylhexanol comes from propylene oxo chemistry, malonic acid from chloroacetic acid, and the syringyl ring from synthetic aromatic syringaldehyde.

How we scored it

C28H46O7, 494.7 Da: two 2-ethylhexyl esters (oxo alcohol), malonate and syringyl (hydroxydimethoxybenzyl) core all taken as petrochemical -> 0/494.7 = 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

Dominant route: bis(2-ethylhexyl) malonate is coupled with synthetic syringaldehyde and the double bond reduced. Lignin-derived syringaldehyde would make the benzyl group (0.34) natural, but it is not a significant commercial source.

In plain English

A synthetic antioxidant ester built from a syringyl (hydroxy-dimethoxy-phenyl) group and two 2-ethylhexyl chains, used as an antioxidant and skin conditioner. It is made from petroleum-derived chemicals.
