Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
