Product Name:Diazolidinyl Urea
English Name:Diazolidinyl Urea
CAS No.:78491-02-8
Aliases:Germall II
Molecular Formula:C8H14N4O7
Physical Properties:Off-white free-flowing hygroscopic powder with a slight formaldehyde odor; melting point approximately 125°C (decomposes); pH of 1% aqueous solution 6.0–8.0; readily soluble in water, soluble in propylene glycol and glycerol, insoluble in ethanol.
Uses:Used as a broad-spectrum preservative in cosmetics, suitable for creams, lotions, shampoos, conditioners, liquid cosmetics and eye cosmetics in both leave-on and rinse-off products. It exhibits inhibitory and killing effects on bacteria, yeasts, molds and fungi, especially effective against Gram-positive bacteria and Escherichia coli. It can be combined with parabens and IPBC to form a highly efficient antimicrobial system. The recommended addition level is 0.1%–0.3%, preferably added below 50°C.
Technical Specifications:
Appearance: Off-white free-flowing hygroscopic powder with a slight formaldehyde odor
pH (1% aqueous solution): 6.0–8.0
Nitrogen content: 19.0%–21.0%
Loss on drying: ≤3.0%
Residue on ignition: ≤3.0%
