How we scored it

Glycerol (natural) esterified with ricinoleic acid (natural, castor oil); condensation water not counted → 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 esterifying vegetable glycerin with ricinoleic acid obtained from castor oil. No petrochemical route is used commercially.

In plain English
