How we scored it

Ester of p-methoxycinnamic acid (sunscreen chromophore) and 2-ethoxyethanol (ethoxylated solvent alcohol), both petrochemical: 0/100=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

Cinoxate is manufactured by esterifying synthetic p-methoxycinnamic acid with 2-ethoxyethanol, both petrochemical-derived. No natural-origin production route exists for this UV filter.

In plain English
