Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

Classification related information

Ready biodegradability: based on a read across to the source substances methanol and methyl acetate the registration substance is considered to be readily biodegradable (please see IUCLID section 5.2.1).

Log Kow: the partition coefficient log Kow of the registration substance was determined to be log Kow = 0.18 (please see IUCLID section 4.7).

Effect values based on read across to Methanol and Methyl acetate

Short-term toxicity:

Fish: 96-hour LC50 = 250 mg/L

Aquatic invertebrates: 48-hour EC50 1026.7mg/L

Algae: 72-hour EC50 (growth rate) > 120 mg/L

Long-term toxicity:

Fish: 200-hour NOEC = 7900 mg/L

Aquatic invertebrates: 48-hour NOEC > 100 mg/L

Algae: 72-hour NOEC (growth rate) = 120 mg/L

Conclusion

No experimental data on the aquatic toxicity are available for the registration itself. Therefore, in accordance with REACH Annex XI, a read across approach with the structural analogues methanol and methyl acetate was applied. The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The acute and chronic aquatic effect concentrations are all > 100 mg/L. The registration substance is considered to be readily biodegradable and its log Kow was determined to be 0.18. Based on these results, the registration substance is not classified for short-term (acute) aquatic toxicity nor for long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Regulation (EU) No 2020/1182.
