Description of key information
Short-term toxicity to fish
In a 96-hour acute toxicity test according OECD TG 203 on Zebrafish (Danio rerio) the test item had no toxic effect on fish at aquatic saturation (i.e. limit test concentration). Accordingly, the 96-h NOEC was determined to be 0.040 mg/L and the LOEC > 0.040 mg/L (based on total product), equivalent to 100 mg/L and > 100 mg/L nominal loading rate respectively.
Short-term toxicity to aquatic invertebrates
In a Daphnia sp. Acute Immobilisation Test according to OECD Guideline 202 with a WAF, the 48-h EC50 was higher than the solubility level of the test item in the test medium, which corresponds to a geometric mean measured concentration of 0.0317 mg/L (EL50: >100 mg/L in nominal).
Toxicity to aquatic algae and cyanobacteria
The test item is a dye which could stain the water and make the performance of an algae toxicity study technically impossible. Thus, the study does not need to be performed according to REACH Regulation Annex XI, section 2.
Toxicity to aquatic plants other than algae
In a Lemna sp. Growth Inhibition Test according to OECD Guideline 221 and Commission Regulation (EC) No 761/2009, Annex VI, C.26 with a WAF, the 7-d EC50 and the NOEC was higher than the solubility level of the test item in the test medium, which corresponds to a geometric mean measured concentration of 0.023 mg/L (EL50: >100 mg/L in nominal).
Toxicity to aquatic microorganisms
In a study according to OECD 209 with activated sludge the test item had no influence on the specific respiration rates up to 1000 mg/L. The EC50 (3h) > 1000 mg/L, NOEC (3h) = 1000 mg/L
Additional information
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.
