Description of key information

MDI/CHA/ODA/DCHA is a multi-component substance. The log Koc of the constituents of the substance were calculated:

The component with CAS# 154099 -21-5 (MDI-CHA/ODA): 7.4

The component with CAS# 43136-14-7 (MDI-ODA/ODA): 10.4 (Koc: 2.48E+010 L/kg)

The component with CAS# 58890-25-8 (MDI-CHA/CHA): 4.4 (Koc: 26977 L/kg)

The component MDI-ODA/DCHA: 8.6

The component MDI-CHA/DCHA: 5.7

In addition, the impurity with CAS# 127194 -10 -9 (MDI/DCHA): 6.9

 

Based on the weighted average log Pow of the substance as a whole: //

Key value for chemical safety assessment

Additional information

The QSAR for the chemical class 'Phenylureas' was considered suitable: Koc (in L/kg) = 11.22 x (Kow)^0.49
