How we scored it

Ca2+ (mineral, natural) 40.08 Da; 2x salicylate (petrochemical, benzene derivative) 274.24 Da; 314.32 total; 40.08/314.30 = 0.13.
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 from a calcium source and salicylic acid, a petrochemical benzene derivative. The calcium counter-ion is mineral-derived.

In plain English

A calcium salt of salicylic acid used as a preservative. The calcium is mineral-derived; the salicylic acid portion is petrochemical.
