How we scored it

Ricinoleic acid (natural, castor oil) + potassium (natural mineral counter-ion) → 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

Produced by neutralising ricinoleic acid from castor oil with potassium hydroxide. No petrochemical route is used commercially.

In plain English

A cleansing and emulsifying ingredient made from ricinoleic acid, castor oil's main fatty acid, combined with potassium. Helps products foam and blend oil with water.
