Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Calculation of PNEC water was based on results obtained in short-term studies on fish, daphnia and algae, namely L(E)C50 > 100 mg/l. These results indicate the lack of acute toxicity for the three trophic levels up to concentration of 100 mg/l.

Conclusion on classification

According to the CLP Regulation (EC n.1272/2008), the threshold of classification of a substance for acute aquatic toxicity is 1 mg/l. This limit is compared with LC50 (96h) for fish, EC50 (48 h) for daphnia and EC50 (72 - 96 h) for algae or aquatic plants.

An experimental value of LC50 96h fish > 100 mg/l loading rate was obtained for Tris(ethyl acetoacetato-O1',O3)aluminium.

A study to assess the short-term toxicity to Daphnia Magna of Tris(ethyl acetoacetato-O1',O3)aluminium was performed and the result of the test was EC50 48h Daphnia Magna > 150 mg/l (nominal concentration).

Toxicity on algae was assessed in 72 -hour test always on Tris(ethyl acetoacetato-O1',O3)aluminium. EC50 for algal growth rate was identified as equal to 112 mg/l (meas.geom.mean) .

No chronic toxicity data is available from long-term studies. In case of lack of chronic data, the potential for chronic toxicity is identified by appropriate combinations of acute toxicity data and lack of biodegradability. The threshold of classification is 100 mg/l.

Tris(ethyl acetoacetato-O1',O3)aluminium  is not toxic for aquatic environment after short-term exposure and it is ready-biodegradable so no classification for both acute and chronic aquatic toxicity is applied according to the CLP Regulation (EC n.1272/2008).
