Description of key information

The log Koc of TREGDMA estimated by calculation was 1.89 (Kow method) and 1.19 (MCI method) (estimated with EPIWEB version 4.1,

KOCWIN v2.00).

Key value for chemical safety assessment

Koc at 20 °C:

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 2.3. Moreover, the substance is readily biodegradable (experimental result please see chapter 5.2.1.).

However, a calculated adsorption coefficient is provided: The log Koc of TREGDMA estimated by calculation was 1.89 (Kow method) and 1.19 (MCI method) (estimated with EPIWEB version 4.1, KOCWIN v2.00).

[LogKoc: 1.89]
