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).
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.
