Description of key information

Log Pow 9.62, calculated with KOWWIN v1.67

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

An experimental log Pow was determined with 6.45 to 7.44 for Isodecyl methacrylate, where the main constituent has a log Pow of 7.44. The calculated log Pow of dodecyl methacrylate (KOWWIN 1.67) is 6.68. Compared with the measured value isodecyl methacrylate the calculated log Pow of dodecyl methacrylate is in the same order of magnitude and therefore the calculation method is valid for this group of substances.

Consequently, the calculated value of 9.62 for octadecyl methacrylate is considered as valid.
