It helps to prevent the growth of bacteria, fungi, and other microorganisms, extending the shelf life of these products. Its mild nature makes it suitable for use in skincare items like lotions, creams, and serums, where it ensures product safety without causing significant irritation. Additionally, it is sometimes employed in pharmaceuticals as an excipient to stabilize formulations and maintain their efficacy. Its solubility in water and compatibility with various ingredients make it a versatile additive in multiple industries.
