How we scored it
Triglyceride of crambe seed fatty acids (mostly C22) plus glycerol; hydrogenation only saturates double bonds. All fragments n=1 (glycerol + fatty acids from seed oil): 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
Dominant route is cultivated crambe seed oil, rich in erucic acid, hydrogenated over a nickel catalyst to a hard, behenic-rich fat. No petrochemical route is known; fully and partially hydrogenated grades differ only in hardness.
In plain English
Crambe seed oil that has been hydrogenated: hydrogen is added to its fatty acids so the liquid oil becomes a firmer, waxy fat. It is used in skincare products as a skin-conditioning ingredient and is made from crambe seeds, a mustard-family crop.
CosIng definition: Hydrogenated Crambe Abyssinica Seed Oil is the end-product of the controlled hydrogenation of Crambe Abyssinica Seed Oil.
