Description of key information

TDI is known to polymerize to a polyurea in the presence of water (Yakabe et al., 1999). Therefore a radiolabeled TDI-derived polyurea was investigated in several soil biodegradation tests. Over several months, evaluation of radiolabeled carbon dioxide could not be detected which indicates < 0.1% degradation.

Key value for chemical safety assessment
