How we scored it
Soluble collagen crosslinked through its own side chains with EDC; EDC is a zero-length coupling agent and leaves no atoms. 1.00.
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
Collagen from bovine, porcine or marine skin is solubilised and crosslinked through amide bonds between its own lysine and acidic side chains. No synthetic route applies.
In plain English
Collagen protein that has been linked to itself to form a more stable, gel-like network. It is used as an emollient and film-former that leaves skin feeling soft and smooth. The protein comes from animal or marine sources.
CosIng definition: Soluble Collagen Crosspolymer is Soluble Collagen crosslinked by N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride
