Key value for chemical safety assessment

Log Kow (Log Pow):
-2.58
at the temperature of:
25 °C

Additional information

A study on the n-octanol/water partition coefficient is technically not feasible (REACH Regulation, Annex XI, 2; Annex VII, 7.8, column II) as MAPTAC fully dissociates in water. Instead of measurement a calculated value will be provided.

The log Kow of MAPTAC estimated by calculation is -2.58 (Epiwin 4.1 KOWWIN v1.68).
