How we scored it

Triricinolein base 933.5Da (glycerin + castor ricinoleic acid, natural) + 3 acetyl caps 126Da (acetic anhydride, petrochemical) = 1059.5Da; 933.5/1059.5=0.88.
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 acetylating castor oil (triricinolein) with acetic anhydride to cap the ricinoleic acid's hydroxyl groups. No alternative route is commercially significant.

In plain English

A modified castor oil, acetylated to change its texture and stability. Used in nail and hair products as a flexible, non-drying film-former.
