Additional information

Conclusion on classification

Conclusive experimental results are available from acute tests for invertebrates (daphnia), algae and microorganism.

Short-term toxicity to fish: waiving based on low water solubility

Short-term toxicity to aquatic invertebrates: 48h-EC50: > 100 mg/L (nominal, WAF) 

Toxicity to aquatic algae and cyanobacteria: 72h-ErL50 of 45.9 mg/L (grow, nominal, WAF)

Biodegradation: not readily biodegradable

Water solublitiy: 10.1 µg/L

Log kow: 5.93

 

Algae was identified as most sensitive species, therefore the effect value 72h-ErL50 of 45.9 mg/L is the critical value for classification.

 

Evaluation is based on classification categories for hazardous to the aquatic environment according to GHS Regulation EC No 1272/2008.

Acute (short-term) aquatic hazard:

Not necessary, lowest value is > 1 mg/L therefore classification is not required.

 

Substances for which adequate chronic toxicity data are not available

Category Chronic 3:

96 hr LC50 (for fish) > 10 to ≤ 100 mg/l and/or

48 hr EC50 (for crustacea) > 10 to ≤ 100 mg/l and/or

72 or 96 hr ErC50 (for algae or other aquatic plants) > 10 to ≤ 100 mg/l. (Note 2)

and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log Kow ≥ 4). (Note 3).

Based on the lowest effect value, an ErL50 of 45.9 mg/L, observed in an acute aquatic toxicity in algae Octadecanoic acid, reaction products with triethylenetetramine has to be classified as hazardous to the aquatic environment with “Aquatic Chronic 3” and labelling with H412 (Harmful to aquatic life with long lasting effects) is required.
