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 3.1. 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 1,3-BDDMA estimated by calculation was 2.51 (Kow method) and 1.89 (MCI method) (estimated with EPIWEB version 4.1, KOCWIN v2.00).
