Imidurea is widely used as a preservative in cosmetic and personal care products due to its antimicrobial properties. It helps prevent the growth of bacteria, fungi, and yeast, extending the shelf life of these products. Commonly found in creams, lotions, shampoos, and makeup, it ensures product safety and stability. Additionally, imidurea is used in pharmaceuticals to preserve the integrity of topical formulations, such as ointments and gels. Its compatibility with a wide range of ingredients makes it a versatile choice for formulation chemists.
