Detailed Analysis
Whey Protein (CAS 84082-51-9) is a polypeptide obtained from the liquid portion of cow's milk after curd separation during cheese-making. In cosmetics, it functions as a skin and hair conditioning agent, providing amino acids (leucine, isoleucine, valine, lysine) that support keratin synthesis, tissue repair, and hydration. It forms a protective film on skin that helps retain moisture. No GHS hazards or EU restrictions apply. However, individuals with dairy/milk protein allergies may experience contact reactions.
