NA/339 FULL PUBLIC REPORT GELPASTE UREA 1. APPLICANT Bostik (Australia) Pty Ltd of 51-71 High Street, Thomastown 3074 has submitted for a standard notification statement with their application for an assessment certificate for Gelpaste Urea. The notified chemical will be used as a component an industrial sealant. 2. IDENTITY OF THE CHEMICAL Gelpaste Urea is not considered to be hazardous based on the nature of the chemical and the data provided. Therefore the chemical name, CAS number, molecular and structural formulae, composition and manufacturing process have been exempted from publication in the Full Public Report and the Summary Report Other names: Gelpaste Urea Marketing name: Marketed as the end-use product Bostik Seal’n’Flex 2637, containing less than 5% w/w of Gelpaste Urea. 3. PHYSICAL AND CHEMICAL PROPERTIES All physico-chemical properties of the urea were determined according to the relevant section of OECD Test Guidelines. Appearance at 20°C and 101.3 kPa: Dry, off-white paste Melting point: 234-238 ºC Boiling Not determined Density: Relative density 1.097 at 23ºC Vapour pressure: 8 x 10-6 Pa at 25 ºC solubility: 0.05 ± 0.02 mg/L at 20 ºC Test not performed due to the low solubility Hydrolysis: in water. Urea linkages are unlikely to hydrolyse under environmental conditions. Partition coefficient: Log Pow = 2.7, determined by HPLC. (n-octanol/water)
