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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reaction mass of tetrasodium 5-{[4-chloro-6-(4-{[2-(sulfonatooxy)ethyl]sulfonyl}anilino)-1,3,5-triazin-2-yl]amino}-4-hydroxy-3-[(4-{[2-(sulfonatooxy)ethyl]sulfonyl}phenyl) diazenyl]naphthalene-2,7-disulfonate and trisodium 5-({4-chloro-6-[4-(vinylsulfonyl) anilino]-1,3,5-triazin-2-yl}amino)-4-hydroxy-3-[(4-{[2-(sulfonatooxy)ethyl]sulfonyl}phenyl)diazenyl]naphthalene-2,7-disulfonate

Biodegradation in water: screening tests
Administrative data

Description of key information
The test item is neither readily nor inherently biodegradable
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
A study according to OECD guideline 301 B was conducted to evaluate the biodegradation potential of the test substance. A solution of the test item in a mineral medium was inoculated and incubated for 28 d under aerobic conditions. During this period the ready biodegradability is determined.
After 28 days a total degradation of 7.2 % ThCO2was achieved. Consequently, the test item is not readily biodegradable under the test conditions.
A study was conducted according to OECD Guideline 302 B (Inherent biodegradability: Zahn-Wellens/EMPA Test). The results of the study indicated that the substance is not inherently biodegradable.The DOC removal of the test item remained below 20% within the 28-day testing period. Adsorption on sludge was not observed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
