How we scored it

Malonate diester of 2-ethylhexanol (synthetic alcohol, 0) condensed with a synthetic phenolic-aldehyde-derived fragment (0) -> 0.0.
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 condensing a syringaldehyde-type aromatic building block with diethylhexyl malonate, itself esterified from petrochemical 2-ethylhexanol. No natural-origin commercial route is used for this specialty antioxidant.

In plain English

A synthetic skin-protecting ingredient that helps stabilise other actives against light exposure. It is made in the lab by combining a synthetic branched alcohol with a man-made aromatic building block.
