How we scored it
Triglycerol (natural) esterified with ricinoleic acid (castor oil fatty acid, natural); both fragments natural = 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 triglycerol with ricinoleic acid, extracted from castor oil. No commercially significant petrochemical route exists.
In plain English
A plant-derived emulsifier made from glycerin and castor oil fatty acid, used to help stabilise creams and lotions.
CosIng definition: 1,2,3-Propanetriol, homopolymer, 12-(R)-hydroxy-9-(Z)-octadecenoates (1:1) (3 mol glycerol average molar ratio)
