AMMONIUM CASEINATE

Description

Ammonium caseinate is a protein-derived ingredient used in various skincare and cosmetic formulations. Sourced from milk proteins, specifically casein, this compound is created through a process of enzymatic hydrolysis and subsequent reaction with ammonium hydroxide. The resulting substance is a water-soluble protein that offers several beneficial properties for skin health and appearance.

In skincare applications, ammonium caseinate functions primarily as a film-forming agent and moisturizer. It creates a protective barrier on the skin's surface, helping to reduce transepidermal water loss and maintain hydration levels. This film-forming ability also contributes to a temporary smoothing effect on the skin, potentially minimizing the appearance of fine lines and wrinkles.

Additionally, ammonium caseinate possesses emollient properties, which can help soften and condition the skin. It may also assist in improving the texture and spreadability of skincare formulations. Some research suggests that protein-derived ingredients like ammonium caseinate may support skin's natural repair processes and provide mild antioxidant benefits.

When formulating with ammonium caseinate, it's important to consider potential allergenicity due to its milk protein origin. Product labels should clearly indicate its presence for consumers with milk allergies.
