Diazolidinyl urea is an effective broad-spectrum antibacterial preservative renowned for its strong efficacy against Pseudomonas species. It is specifically designed for use in personal care formulations as it is non-irritating to the eyes, skin, and mucous membranes when used at appropriate levels. This compound is highly soluble in water and maintains its preservative action in the presence of proteins, nonionic surfactants, and most common ingredients. It can be directly added to aqueous solutions without requiring heat. In formulations involving a hot process, diazolidinyl urea should be introduced during the cooling phase, ensuring temperatures are below 60°C, and ideally under 40°C, to maintain its stability. Due to its hygroscopic nature, it is crucial to store this preservative in tightly sealed containers to preserve its quality and efficacy when not in use.
What is Diazolidinyl Urea?
