Route-dependent · ISO 16128

Is Vanillic Acid natural?

It depends. Simple phenolic acid obtainable either by synthetic oxidation of guaiacol or by conversion of plant-derived ferulic acid; route determines origin entirely.

Why the score varies

This ingredient is made commercially by more than one route, and ISO 16128 scores the feedstock actually used. Without a supplier certificate of origin the value cannot be claimed.

Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

Two routes: petrochemical guaiacol oxidation (C8H8O4, 0/168 = 0.0) vs bio-conversion of natural ferulic acid from bran (168/168 = 1.0); dominant share uncertain.
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

Commodity vanillic acid is most often made by oxidising synthetic guaiacol, the same petrochemical route used for synthetic vanillin. A smaller natural-origin supply is made by extracting or bio-converting ferulic acid from rice or wheat bran.

In plain English

A phenolic acid used in cosmetics that can be made either by chemically processing a petrochemical compound or by converting a natural plant acid from rice or wheat bran. Its natural content depends entirely on which manufacturing route was used.
