Description of key information

In the key study (OECD SIDS, 1995), the partition coefficient log Pow was

determined experimentally to be -0.47 at 26 °C for TMP. Another value of logKow = -2.4 supports the finding that trimethylolpropane has a low tendency to be partitioned into octanol.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
