Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Environmental fate and pathways:

The registered substance is readily biodegradable and therefore is not persistent. In addition, the log Kow value was determined as 0.2 and therefore the substance is not considered likely to bioaccumulate.

Aquatic toxicity:

One experimental study of reliability 1 (based on international guideline and GLP compliance) and two QSAR results are available to assess the aquatic toxicity of the registered substance, on aquatic invertebrates and algae.

The experimental growth inhibition study on the algaePseudokirchneriella subcapitatawas performed on the registered substance. In this study, the 72h-ErC50 value for growth rate, based on geometric mean measured concentrations, was determined to be 169.4 mg/L (95%-Confidence Limit: 147.3 – 193.2 mg/L). This study was supported by a conservative QSAR result on algae performed on the registered substance also.

The QSAR predictions (iSafeRat holistic approach v1.5) have been validated to be compliant with the OECD recommendations for QSAR modeling (OECD, 2004) and predict the ecotoxicological values which would be expected when testing the substance under experimental conditions in a laboratory following OECD Guidelines. The growth inhibition of algae and immobilisation of daphnids were determined using a validated QSAR for the Mode of Action in question (ester) using training sets for which the concentrations of the test substance had been determined by chemical analyses over the test period. The 72h-ErC50 value based on growth rate of algae was determined to be 81 mg/L (95% CL: 29 - 221 mg/L). This predicted toxicity value was found to be comparable and more conservative than the in vivo result at 169.4 mg/L. For the short-term toxicity to aquatic invertebrates endpoint, the iSafeRat QSAR model was validated for use with the same applicability domain and under the same conditions as the algae QSAR using a holistic approach. Thus, the prediction method can be considered sufficient to assess, in a conservative way, the toxicity of the registered substance to daphnid. The 48h-EC50 value based on mobility was determined to be368 mg/L (95%-CL: 139 - 972 mg/L). An in vivo acute daphnia study is therefore not considered necessary.

Conclusion on classification

No harmonised classification is available.

EC50 value > 100 mg/L; readily biodegradable; log Kow = 0.2.

Classification according to the Annex VI of the Regulation (EC) No 1272/2008 (CLP): The registered substance is not classified for the environment.
