Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Melam is of low ecotoxicity.

Conclusion on classification

Melam is of low ecotoxicity. The LC50/EC50s are above 100 mg/L for the acute exposure. The NOEC for Daphnia at long-term exposure is 2.9 mg/L. The water solubility is 24.5 mg/L; melam is not ready biodegradable, has no bioaccumulation potental and has a low logPow of <-1.0. Altogether there are no indications for a classification of melam, based on ecotoxicity and/or fate and behaviour in the environment.

Melam is not a PBT or vPvB-substance because of the low bioconcentration potential, the low partition coefficient n-octanol/water and the low ecotoxicity.
