Description of key information

One OECD 301D GLP test is available where the Reaction mass of 1,15-dichloro-3,5,8,11,13-pentaoxapentadecane and 1-chloro-2-[(2-chloroethoxy)methoxy]ethane and 1-chloro-2-{[2-(2-chloroethoxy)ethoxy]methoxy}ethane is not readily biodegradable in the Closed Bottle test, but should  be classified as inherently biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable, not fulfilling specific criteria

Additional information

The Reaction mass of 1,15-dichloro-3,5,8,11,13 -pentaoxapentadecane and 1-chloro-2-[(2-chloroethoxy)methoxy]ethane and 1 -chloro-2-{[2-(2-chloroethoxy)ethoxy]methoxy}ethane is not biodegraded in the Closed Bottle test and should therefore not be classified as readily biodegradable. Lack of biodegradation does not mean that the reaction mass of bis(2-chloroethoxy)methane and 1,15-dichloro-3,5,8,11,13 -pentaoxa-pentadecane is recalcitrant in nature. The stringency of the test procedures could account for the recalcitrance in the Closed Bottle test.
