How we scored it
Whole fixed oil expressed from sunflower seeds; triglyceride fatty acids are entirely plant-derived carbon, no petrochemical fragment present → 1.0 by botanical-oil convention.
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
Commercial supply is mechanically expressed (cold-pressed) or solvent-extracted from sunflower seeds grown widely in Europe, Ukraine and Argentina. No petrochemical route exists; refining removes mass but adds none.
In plain English
A light, non-greasy oil pressed from sunflower seeds, used to soften and condition skin and hair. It comes straight from the plant with no chemical modification of the oil itself.
CosIng definition: Helianthus Annuus Seed Oil is the fixed oil expressed from the seeds of the sunflower, Helianthus annuus.
