Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Short-term aquatic toxicity to invertebrates

EC50 (48h) = 6.8 mg/l

Toxicity to aquatic plants other than algae

ErC50 = 10.6 mg/l (effects on dry weight)

NOErC < 3.36 mg/l (effects on dry weight)

Additional information

Justification for classification or non-classification

According to the CLP Regulation (EC n. 1272/2008), Part 4: Environmental Hazards, the substances can be classified for hazardous to the aquatic environment (fish toxicity) when the following criteria are met:

Long-term aquatic hazard

(iii) Substances for which adequate chronic toxicity data are not available

Category Chronic 2:

96 hr LC 50 (for fish) > 1 to ≤10 mg/l and/or

48 hr EC 50 (for crustacea) > 1 to ≤10 mg/l and/or

72 or 96 hr ErC 50 (for algae or other aquatic plants) > 1 to ≤10 mg/l (Note 2)

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

The EC50 value calculated for Similar Substance 01 on the "short-term aquatic toxicity to invertebrates" (Daphnia) was established to be 6.8 mg/l, therefore the substance is classified as Category Chronic 2 (48 hr EC 50 (for crustacea) > 1 to ≤10 mg/l) according to the CLP Regulation (EC n. 1272/2008).
