How we scored it

C8 fatty acid (caprylic, oleochemical) 143 Da + Na (mineral) 23 Da; both natural. 166/166 = 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

Made by neutralising caprylic acid, derived from coconut or palm kernel oil, with sodium hydroxide. No petrochemical route is used commercially.

In plain English
