Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
In accordance with column 2 of REACH Annex IX, the bioaccumulation in aquatic species study does not need to be conducted as the substance has a low potential for bioaccumulation (the substance has a log octanol water partition coefficient less than -3).
This is supported by a QSAR determination. The QSAR determination of the BCF of the acid form of the substance using the BCF-model BCFBAF v.3.01 included in the Estimation Program Interface (EPI) Suite v4.1 revealed a value of 3.16 L/kg wwt (logBCF= 0.500) at 25°C. The predicted result can be considered reliable yielding a useful result for further assessment.
The substance is an organic salt of strong base NaOH and weak acid and hence it dissociates 100 % in water solution and its BCF depends on the property of the related acid.
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.
