How we scored it
6 glycerol units (natural, condensation-polymerised) esterified with ricinoleic acid (castor oil, natural); condensation water not petrochemical mass → 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 polymerising glycerin (from fats/oils) into hexaglycerol, then esterifying it with ricinoleic acid from castor oil. Both building blocks are plant/fat derived.
In plain English
An emulsifier made by linking glycerin units to castor oil's ricinoleic acid. Both building blocks are plant/fat derived, so the finished ester is considered fully renewable.
CosIng definition: 1,2,3-Propanetriol, homopolymer, 12-(R)-hydroxy-9-(Z)-octadecenoates (1:1) (6 mol glycerol average molar ratio)
