Diazolidinyl urea (CAS 78491-02-8)

Diazolidinyl urea, a widely used antimicrobial preservative in cosmetic and personal care products, has garnered research attention primarily for its antimicrobial properties and potential applications in product preservation. Functioning as a formaldehyde releaser, diazolidinyl urea acts by slowly releasing formaldehyde when in contact with water, thereby inhibiting microbial growth in various formulations. Its mechanism involves the reaction of formaldehyde with amino and hydroxyl groups of proteins and nucleic acids, ultimately disrupting microbial cell structures and functions. Research has focused on optimizing diazolidinyl urea concentrations in cosmetic products to ensure effective antimicrobial activity while minimizing potential adverse effects, such as skin irritation or sensitization. Additionally, investigations have explored its compatibility with different formulation ingredients and its stability under various storage conditions. Studies have also delved into alternative preservative systems to address concerns related to formaldehyde release, aiming to develop safer and more environmentally friendly options for product preservation. Overall, the research on diazolidinyl urea underscores its significance in cosmetic science and the ongoing efforts to ensure product safety and efficacy through effective antimicrobial preservation strategies.
