Whey Protein
What is Whey Protein?
Whey Protein consists of a blend of globular proteins, mainly beta-lactoglobulin and alpha-lactalbumin, extracted from whey—the watery byproduct of cow's milk during cheese-making. This natural dairy-derived ingredient falls under protein-based conditioners in cosmetics, appearing in hair care items like shampoos and conditioners, as well as skin moisturizers and lotions. It works by coating hair shafts and skin surfaces to create a thin, flexible film that locks in moisture, minimizes friction between strands or skin cells, and promotes a silky texture. Its humectant qualities draw water to the surface, while mild cationic properties aid in static reduction and detangling. Typically processed via hydrolysis for enhanced solubility and compatibility in formulations, it supports product stability without adding weight or oiliness.
