Description of key information

The log Koc of MAPTAC estimated by calculation was -0.62 (Kow method) and 1.68 (MCI method) (EPIWEB version 4.1, KOCWIN v2.00). 

Key value for chemical safety assessment

Additional information

In accordance with column 2 of REACH annex IX, 9.3.1., no study on adsorption/desorption is required based on a log Kow of -2.58.

However, a calculated adsorption coefficient is provided: The log Koc of MAPTAC estimated by calculation was -0.62 (Kow method) and 1.68 (MCI method) (estimated with EPIWEB version 4.1, KOCWIN v2.00).
