Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Adequate chronic toxicity data are not available for Direct Blue 199 Na, therefore the aquatic toxicity assessment and classification are based mainly on the short-term toxicity data available on both Direct Blue 199 Na and Direct Blue 199 Na/NH4. The usage of information on a different salification form, which has the same main component and with a different counter ion, can be considered as suitable and appropriated because the difference is expected to not influence the ecotoxicological properties. The impurity profile does not impact on the read across proposed. Details on the approach followed are included in the document attached to the IUCLID section 13.

 

The key values chosen for Chemical Safety Assessment concerning the aquatic compartment are the following:

- the substance resulted to be not harmful/toxici for short-term toxicity to fish, thus the LC50 (96 h) can be considered tio be higher than 100 mg/l

- for short-term toxicity to aquatic invertebrates the EC50 (48 h) resulted to be greater than 100 mg/l

- for toxicity to aquatic algae and cyanobacteria the EC50 (72 h) has been identified as higher than 1000 mg/l

- for toxicity to microorganisms the no inhibition was recorded at dose of 2000 mg/l

 

The substance resulted to be non harmful/toxic for none of the tested organisms, thus the limit value of 100 mg/l has been chosen for the PNEC water (both freshwater and marine water) derivation.

Conclusion on classification

Adequate chronic toxicity data are not available; the substance is very water soluble, not readily biodegradable and has a negative log kow.

 

On the basis of the short-term toxicity data on the three trophic levels, the substance does not meet the criteria to be classified as hazard to the aquatic environment, according to the CLP Regulation (EC) No 1272/2008.
