Description of key information

The study does not need to be conducted because the substance has alow potential for bioaccumulation based on log Kow ≤ 3.

Additional information

Available data for all main components of Tar acids, xylenol fraction (CAS 84989-06-0) demonstrate the log Kow to be below 3, i.e. xylenol-isomers: 2.09 to 2.42 (DEZA, 2010; EPA, 2010; Sangster, 1989); cresol-isomers: 1.94 to 1.98 (OECD SIDS, 2003; Sangster, 1989); ethyl-phenols: 2.09 to 2.58 (DEZA, 2010; Umeyama et al., 1971; Sangster, 1989), or trimethyl-phenols: 2.67 to 2.73 (Sangster, 1989). Thus, Tar acids, xylenol fraction (CAS 84989-06-0) exhibits a low potential for bioaccumulation and in accordance with Regulation (EC) No 1907/2006, Column 2 of Annex IX, section 9.3.2, a study on the bioaccumulation in aquatic species does not need to be conducted.
