How we scored it
Hexadecanoyl (palmitic acid) amide-bonded to isoleucine (amino acid) minus condensation water; both fragments natural: oleochemical fatty acid + fermentation amino acid. 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 acylating isoleucine (a fermentation-derived amino acid) with palmitic acid from vegetable oil. No petrochemical fragment remains in the molecule.
In plain English
A compound combining palmitic acid, a plant-oil fatty acid, with isoleucine, an amino acid. Used to protect and condition skin, built from natural fat and amino-acid sources.
