Hydrolyzed Keratin Cas No: 69430-36-0 is made from waterfowl feather, which is consisted of Keratin like human hair. It is Amino Acid composition very similar to human hair. Besides, the structure of the Keratin from feather is different with Wool’s keratin. The feather keratin molecules have many β-sheet structures, so we call β-keratin. Because of its planar structure, it has a very flexible molecular structure. By biological enzyme hydrolysis processing, we cut the high molecular weight Keratin to keratin peptide with small molecular weight, which is water-soluble and better compatibility with cosmetics formulations.
