How we scored it

Ricinoleoyl (natural, castor oil) C18H33O2 281.5 Da; ethylene glycol fragment (petrochemical) 61.1 Da → 281.5/342.5 = 0.82.
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 ricinoleic acid, the principal fatty acid in castor oil, with ethylene glycol derived from petrochemical ethylene oxide. No significant bio-based ethylene glycol route is used commercially.

In plain English

An ester made from ricinoleic acid, the main fatty acid in castor oil, combined with ethylene glycol. Used as an emollient and emulsifier that helps blend oil and water and softens skin.
