Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Acute aquatic toxicity data were avaialbel for three trophic levels (fish, daphnia and algae), with daphnia being the most sensitive species with an LD50 of 7.7 mg/L. This values was used to derive the PNEC for intermittent release.
As two long-term NOECs from species presenting two trophic levels (daphnia and algae) are available and one of these (daphnia) is from the species with the lowest short-term L(E)C50, the lower NOEC, i.e. of 1.3 mg/L from the daphnia study, was used to derive the PNECs for freshwater and marine water (using an assessment factor of 50).
Sediment PNECs (freshwater and marine water) were derived by means of the equilibirum partitioning method.
The PNEC soil was calculated on the basis of one relevant long-term toxicity study.
The PNEC STP was derived from an EC50 of a study investigating the toxicity to microorganisms.
The PNEC for secondary posining was not derived, as the registered substance is readily biodegradable.
Conclusion on classification
As the registered substance is rapidly biodegradable, has no potential for bioaccumulation (log Kow < 3.44) and chronic toxicity is > 1 mg/L, no classification is required (acc. to Commission Regulation (EU) No 286/2011: Table 4.1.0 (b) (ii)).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
