Description of key information

2,6 DIPN is not readily biodegradable according to OECD requirements.

Additional information

No biodegradation study concerning only 2,6-diisopropylnaphthalene (CAS 24157-81-1; 2,6-DIPN) was available. But two GLP studies according to OECD 310 examining the primary and ultimative biodegradation of Bis(isopropyl)naphthalene (DIPN), an isomeric mixture which consist of seven isomers (1,3-, 1,4-, 1,5-, 1,6-, 2,6- and 2,7-DIPN) is available and used in a read-across approach.

Based on the determined results 2,6-diisopropylnaphthalene is not readily biodegradable regarding OECD criteria.
