How we scored it
Azelaic acid (from oleic acid ozonolysis, natural) amide-linked to two glycine molecules (amino acid, natural), potassium salt; all 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
Azelaic acid, obtained from oleic acid (vegetable oil) via ozonolysis, is amide-linked to glycine and neutralised as the potassium salt. No petrochemical route is used commercially.
In plain English
A brightening, skin-conditioning ingredient made from a plant-oil-derived acid combined with a simple amino acid, used in serums for uneven skin tone.
Structure
potassium 2-[[9-(carboxymethylamino)-9-oxononanoyl]amino]acetate
