o-Phenylphenolate (169.20 Da, petrochemical biphenyl-phenol) + Na+ (22.99 Da, mineral, natural) → 22.99/192.19 = 0.12.
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 producing petrochemical o-phenylphenol from biphenyl, then neutralizing with sodium hydroxide. No natural production route exists.
