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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
No data with the test substance were available. From the guidance document R.7b, Chapter R.7.8.7.: "Substances that are potentially capable of depositing on or sorbing to sediments to a significant extent have to be assessed for toxicity to sediment-dwelling organisms. In general substances with a Koc < 500 – 1000 L/kg are not likely sorbed to sediment (SETAC 1993). According to this, a log Koc or log Kow of >=3 is used as a trigger value for sediment effects assessment." Both melamin phosphate and melamin have logKow values << 3. Therefore, the compounds will not end up in the sediment compartment. Therefore, a read-across from pelagic effect values is possible as a screening approach by the equilibrium partitioning method. Melamine has a low toxicity to mammals and aquatic organisms, not leading to a classification. Thus, is no need to investigate further the effects of the substance and/or degradation products in sediment organisms.

Additional information
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.
