Used in skincare products for its cleansing and foaming properties, sarcosine helps improve the texture and stability of formulations. It acts as a mild surfactant and is often included in facial cleansers and shampoos for sensitive skin. In pharmaceuticals, it serves as an intermediate in the synthesis of certain drugs and contributes to the development of antimicrobial agents. It is also studied for its potential role in neurological research due to its involvement in glycine regulation in the brain. Additionally, sarcosine finds use in biochemical research as a buffer component and stabilizer in enzyme assays.
