Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

In general textile chemicals especially textile dyes are designed to be no organic substrates for microorganisms, fungi and higher organisms. Therefore these substances are considered to be not biodegradable. Nevertheless, basic studies to assess biodegradability of the target substance have been performed.

A key study to evaluate the inherent biodegradability indicated, target substance to be not inherently biodegradable. Further, multiple studies evaluating BOD5 and COD are available. The relevant BOD5/COD quotient is <0.5 in all cases, indicating substance to be not rapidly degradable. Taking the data from key and supporting studies into account, the target substance is considered to be neither rapidly nor inherently biodegradable.
