Milk Protein Extract
What is Milk Protein Extract?
Milk Protein Extract is derived from cow's milk, consisting mainly of casein (about 80%) and whey proteins such as beta-lactoglobulin, alpha-lactalbumin, and immunoglobulins. It falls under skin conditioning agents in cosmetics, functioning as both a humectant and emollient. This ingredient draws moisture into the skin and forms a lightweight film that locks in hydration, enhancing smoothness and suppleness. Typically incorporated into moisturizers, lotions, creams, shampoos, and conditioners at low concentrations, it provides a nourishing, velvety texture without heaviness. Its amino acid profile supports the skin's natural barrier, promoting a comfortable feel on both face and body products.
