Casein

Description

Casein is a protein complex found predominantly in mammalian milk, particularly abundant in cow's milk. This versatile ingredient has gained significant attention in the skincare industry due to its multifaceted benefits. Composed of several types of phosphoproteins, casein forms micelles in milk, which contribute to its unique properties when applied topically.

In skincare formulations, casein functions as an effective moisturizing agent, forming a protective film on the skin's surface that helps retain hydration. Its high molecular weight allows it to create a smooth, supple feel on the skin without clogging pores. Casein also contains essential amino acids that can potentially support collagen synthesis and skin repair processes.

Furthermore, casein exhibits antioxidant properties, helping to neutralize free radicals and protect the skin from oxidative stress. Some studies suggest that casein peptides may have mild anti-inflammatory effects, potentially benefiting sensitive or irritated skin. In hair care products, casein can improve hair strength and texture by binding to the hair shaft.

When formulating with casein, it's important to consider its pH sensitivity and potential allergenic properties for individuals with milk protein sensitivities. Proper preservation methods are crucial to maintain product stability and safety.
