Description of key information

The hydrolysis of Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, caprolactam-blocked was tested according to OECD TG 111 (2004) and EU Method C.7 (2008). In the preliminary test, less than 10% of the test substance was observed to hydrolyse at 50 °C at pH 4,7 and 9 after 120 hours. Performance of the main test was not required. According to the guideline a half life of > 1 year under environmental conditions can be assumed.
