How we scored it
2x undecylenate (castor-oil fatty acid) 366.55 Da natural + Ca (mineral counter-ion) 40.08 Da natural; both natural, 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
The calcium salt of undecylenic acid, produced by pyrolysis of castor oil-derived ricinoleic acid. No petrochemical route is used.
In plain English
