Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key study on acute toxicity to Daphnia (2010): EC50(48h) = 3.2 mg/L
Read-across to the chemically related substance rosin (2002): EL50(48h) (EL=effective loading rate) = 911 mg/L.

Key value for chemical safety assessment

Additional information

The test substance has a very low solubility in water (<0.1 mg/L). The solubility is higher in buffered media like those used for daphnia tests.

In a recent study (2010) the EC50(48h) was 3.2 mg/L, the NOEC(48h) was 0.39 mg/L. The test substance solutions were prepared as WAFs (water accomodated fractions) with separate loading rates for each concentration. WAFs from the highest loading rates of 500.5 and 992 mg/L resulted in actual test substance concentrations of ca. 20.2 mg/L.

In a study performed with WAFs of the chemically related substance rosin the effective loading rate EL50(48h) was 911 mg/L and the no observed effective loading rate NOELr was 750 mg/L. No analytical measurements were made in this study.
