How we scored it

Hydrolysed protein = 1.0 by this site's 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

Made by hydrolysing the protein membrane found inside egg shells, a byproduct of egg processing. No synthetic alternative route exists.

In plain English

A protein from the membrane inside egg shells that has been broken down into smaller fragments. Used in skincare to attract moisture and condition the skin.

CosIng definition: Hydrolyzed Egg Shell Membrane is the hydrolysate of egg shell membrane derived by acid, enzyme or other method of hydrolysis.
