Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The reaction mass is produced at one manufacturing site and is then used by the paper industry for the production of paper by the Kraft process.
At the manufacturing site, exposure to the substance via releases to the aquatic compartment is very limited. During the concentration step of the reaction mass, water is removed to concentrate the inorganic and organic salts. Release to the aquatic compartment would be possible from this water resulting from this concentration step. Thus based on the process, the wastewater would contain a very limited amount of the reaction mass and is treated by the on-site sewage treatment plant thus resulting in a non significant exposure of the aquatic compartment to the reaction mass.
The use of the reaction mass by the paper industry is done in a closed system where it is entirely consumed during the Kraft process. Thus the use of the substance by the paper industry results in no exposure of the environment to the reaction mass.
On the top of that, referring to the certificate of analysis and the provided information the test substance is mixtures of different salts, i.e. mainly consisting of inorganic compounds. An experimental determination of the partition coefficient using HPLC method is not feasable as the compounds will not be retained on a C18 column. Thus our proposal was to do a theroretical estimation of the log Pow. The estimated value comes to reinforce the assumption of a low potential of adsorption.
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.
