Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Long-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
Waiver: due to negligible exposure to aquatic organisms and no adverse effects to invertebrates are expected. Therefore, no further testing is needed.
Key value for chemical safety assessment
Additional information
Under Column 2 of the Annex IX of Regulation (EC) No 1907/2006 the specific rules for adaptation from Column 1 are that the long-term toxicity testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the effects on invertebrates. It is proposed that testing is waived as exposure potential is negligible. The substance has a very low log octanol-water partition coefficient (log Kow) of 0.41 at a neutral pH. The low log Kow indicates the substance has a low adsorptive and bioaccumulative potential. There is negligible exposure to aqueous process streams during downstream use and hence also negligible emission to a sewage treatment plant. It is proposed that testing is waived as exposure is negligible.
The short-term invertebrate study reported in this assessment provides evidence of the low toxicity to invertebrates with lethal concentrations (LC50) greater than 100.2 mg/L.
Therefore, under such conditions and due to negligible exposure to aquatic organisms and no adverse effects to invertebrates are expected. Therefore, no further testing is needed.
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.
