How we scored it
Brucine (plant alkaloid, extracted) x2 + H2SO4 (mineral-derived counter-ion, natural per this site's convention) = C46H54N4O12S, 887/887 = 1.0.
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
Brucine is extracted from Strychnos nux-vomica or S. ignatii seeds, then converted to its sulfate salt with sulfuric acid. Total chemical synthesis of brucine is not used commercially.
In plain English
The sulfate salt of brucine, a bitter plant alkaloid extracted from Strychnos nux-vomica seeds, used in tiny amounts to deter product misuse.
