Description of key information
In accordance with column 2 of REACH Annex VII, the study does not need to be conducted as the substance is hydrolytically unstable (half-life <12 hours).
Key value for chemical safety assessment
Additional information
Although the endpoint was waived a non-standard test has been performed in order to characterise the solubility of Desmodur N 3300 after complete hydrolysis. Desmodur N 3300 (500 mg) was allowed to drop into water while stirring. Most of the substance adhered to the wall. About 4% of the material after hydrolysis was found to be soluble. A solubility of approx. 20 mg/L can be estimated from DOC- and TNb-determination. This is, however, the total of dissolved compounds and does not represent the water solubility of the registered substance. This data was included to report of all available data but it may not be considered for the CSA.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
