How we scored it
Protein hydrolysate of animal elastin; hydrolysis leaves only water as a byproduct → 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
Hydrolyzed Elastin is produced by breaking down natural elastin protein from animal connective tissue into smaller peptide fragments using acid, enzymes, or another hydrolysis method. No petrochemical material is introduced.
In plain English
A skin- and hair-conditioning ingredient made by breaking down animal-derived elastin protein into smaller pieces that coat hair and skin.
CosIng definition: Hydrolyzed Elastin is the hydrolysate of elastin derived by acid, enzyme or other method of hydrolysis
