Description of key information

The water solubility of 3-Isocyanatomethyl-3,5,5-trimethylcyclohexyl isocyanate, oligomers, reaction products with 3,5-dimethyl-1H-pyrazole in demineralized water was determined with the flask method at 20 °C according to OECD TG 105. The concentration of the test item in the aqueous test solutions was determined substance-specific by HPLC-MS-analysis. The test item was determined to be insoluble in demineralized water within the test duration and remains as an undissolved solid residue. The water solubility is < 0.1 mg/L at 20 °C.

Key value for chemical safety assessment

Water solubility:
0.1 mg/L
at the temperature of:
20 °C

Additional information

The water solubility is < 0.1 mg/L at 20°C.
