Description of key information
Additional information
Bis(isopropyl)naphthalene (DIPN) is an isomeric mixture, which consists of seven isomers (1,3-, 1,4-, 1,5-, 1,6-, 2,6- and 2,7-DIPN). Bioaccumulation potential differs between the isomers. According to OECD 305 the lipid normalized BCF values were determined to range between 810 -2500 (low dose group; 0.47 µg/L) and 2200-7800 (high dose group; 4.85 µg/L), respectively. Hence, some isomers of bis(isopropyl)naphthalene fulfil the criterion of being bioaccumualtive (BCF > 2000). Although the environmental relevance of the results from the high exposure concentration is questionable (see expert statement ECT, 2017) the highest measured BCF value of 7800 was used as an worst case assumption for the bioaccumulation assessment. Therefore, the isomeric mixture bis(isopropyl)naphthalene (CAS 38640-62-9) was assessed as bioaccumulative (B) and potentially very bioaccumulative (vB) under environmental conditions.
