Description of key information

Bayscript Blaukomponente TEA is highly soluble in water (> 841.7 g/L). The following results provide read-across data from Bayscript Blaukomonente MDA. The read-across approach is based on high structural similarity between Bayscript Blaukomponente MDA (source) and Bayscript Blaukomponente TEA (target).

6.1.1 Acute toxicity to fish: No toxic effects against fish (Danio rerio)were observed under exposure conditions at a limit test concentration of 100 mg/L (96 h-LC50 > 100 mg/L).

6.1.3 Acute toxicity to daphnia:No toxic effects against daphnia (Daphnia magna) were observed at a limit test concentration of 100 mg/L (48 h-EC50 > 100 mg/L) under exposure conditions.

6.1.5 Toxicity to algae: The toxicity to algae (Desmodesmus subspicatus) of the active ingredient of the substance was determined on the growth rate and showed an ErC50 of 43 mg/L and an ErC10 of 2.4 mg/L after 72 hours. A NOEC of >= 2.4 mg/L was calculated.

6.1.7 Toxicity to microorganisms:Solvent Yellow 179 showed 0.0 % respiration inhibition of activated sludge at the highest test concentration (860 mg/L) and an EC50 of higher than 860 mg/L was determined. Test concentrations are given as nominal concentrations.

All studies were conducted according to national and/or international guidelines. The toxicity studies are classified as acceptable and satisfy the guideline requirements.
