Hydrolyzed Milk Protein
What is Hydrolyzed Milk Protein?
Hydrolyzed milk protein is produced by breaking down proteins from cow's milk into smaller peptides using enzymatic or chemical hydrolysis. This process yields bioavailable fragments that are incorporated into hair care products like shampoos and conditioners, as well as skincare items such as moisturizers and lotions. In formulations, it functions primarily as a conditioning agent by depositing a thin, protective film on the hair cuticle and skin surface. This film helps seal in hydration, minimizes friction between strands for easier combing, and enhances overall texture. Its proteinaceous nature allows it to penetrate slightly into damaged areas, supporting structural integrity without weighing down products. Commonly used at low concentrations, it contributes to formulations aimed at daily maintenance of hair manageability and skin suppleness, leveraging milk's natural amino acid profile for compatibility with human tissues.
