Diazolidinyl Urea, IPBC - AKA Liquid Germall Plus

Diazolidinyl Urea and IPBC are broad-spectrum preservative agents commonly used in cosmetic and personal care formulations. Diazolidinyl Urea functions as a formaldehyde-releasing preservative, offering reliable antimicrobial protection against bacteria, fungi, and yeast. IPBC (iodopropynyl butylcarbamate) complements this action with enhanced efficacy against resistant microorganisms.

Together, these ingredients create a robust preservation system suitable for aqueous and emulsion-based products. Both are approved for use in cosmetics within regulated markets and are valued for their stability and cost-effectiveness in extending shelf life while maintaining product integrity.
