How we scored it

Collagen natural; succinoyl C4H5O3 101.1 petrochemical on lysine amines, assumed one per ~3,000 Da collagen: 3000/3101 = 0.97.
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 reacts bovine, porcine or marine atelocollagen with succinic anhydride, which is made from petrochemical butane via maleic anhydride. Fermentation-derived succinic acid is a minor alternative.

In plain English

A modified collagen used as a skin-conditioning and moisturising ingredient. Collagen from animal skin or fish is treated with succinic anhydride so that it dissolves more readily and carries a different charge.

CosIng definition: Succinoyl Atelocollagen is the product formed by the reaction of succinic anhydride and atelocollagen (q.v.)
