How we scored it
Unsaponifiable fraction of avocado oil (sterols, tocopherols, hydrocarbons, furan lipids) is all oil-derived (n=1); separation adds no mass. 1 / 1 = 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
The fraction of avocado oil that does not saponify is recovered and concentrated during the refining of avocado oil fatty acids. No synthetic route exists; any carrier oil would be declared separately on the INCI.
In plain English
The oil-soluble part of avocado oil that stays behind when the oil is split into soap or fatty acids, containing plant sterols and other lipids. It is used in skin and hair care for conditioning, and comes entirely from avocados.
CosIng definition: Persea Gratissima Oil Unsaponifiables is the fraction of Persea gratissima oil which is not saponified in the refining recovery of avocado oil fatty acids
