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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
Key information for classification
Degradation
Biodegradation: not readily biodegradable (10% degradation after 28 d (O2 consumption, OECD 301F)
Bioaccumulation
Log Kow: 4.64 (OECD 117, HPLC method)
Aquatic acute toxicity
For aquatic invertebrates: 48 h, EC50 (Daphnia magna, OECD 202): 1.6 mg/L (geometric mean measured)
For algae/aquatic plant: 72 h, ErC50 (Pseudokirchneriella subcapitata, OECD 201): > 1.0 mg/L (geometric mean measured)
Aquatic chronic toxicity
For algae: 72 h, ErC10 (Pseudokirchneriella subcapitata, OECD 201): 1.1 mg/L (geometric mean measured)
Conclusion on CLP
The test item is considered to be not rapidly degradable. Acute toxicity data are available for two trophic levels algae and aquatic invertebrates.The lowest acute aquatic toxicity EC50 value is between 1 and 10 mg/L. Long-term data are available for one trophic level only (algae ErC10 =1.1 mg/L). Therefore, the substance needs to be classified and labelled as Chronic Category 2 for environmental hazards according to the consolidated version of Regulation (EC) No 1272/2008 (date: 01.01.2017) and further amendments (ATPs).
The impurity ally alcohol CAS 107 -18 -6 bears a harmonized classification of Aquatic Acute 1. However the maximum concentration of the impurity in the substance is clearly below 25% and therefore according to the summation method of the CLP Regulation (EC) No 1272/2008 it does not affect the classification of the substance.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
