Additional information

In accordance with column 2 of REACH Annex VIII, a study does not need to be conducted as the substance is highly insoluble in water.

But rapid hydrolysis (as for isocyanates in general) is considered for the substance. The hydrolysis products are mainly insoluble oligomeric and polymeric ureas. Theoretically the corresponding amine can be regarded which however is not formed in significant concentrations.

Using a read-across study from a chemically related substance it can be concluded that the test item undergoes a complete hydrolysis reaction in demineralized water within 24 hours and remains as hydrolysis product in form of an undissolved solid residue.
