Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Executive summary:

According to Column 2 of Section 9.6.1 in the Annex X of REACH "Any need for testing should be carefully considered taking into account the large mammalian dataset that is usually available at this tonnage level."

Melam has a low toxicity to mammals with NOAELs of 1000 mg/kg bw respectively 500 mg/kg bw in the subchronic toxicity and the developmental toxicity tests. Melam is also of low toxicity to aquatic organisms, not leading to a classification. Melam is not bioaccumulative, and is not a PBT or vPvB-substance. No avian specific indications were obtained up to now that an assessment of secondary poisoning for the aquatic and terrestrial food chains for birds could not be performed by using the mammalian PNEC and applying an additional assessment factor of 10 for birds, as suggested in the Integrated Testing Strategy in the Guidance Document R.7c.

According to Column 2 of Section 9.4. in the Annex X of REACH "These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely." A direct exposure of soil is not intended and an indirect exposure to soil is unlikely, as melam is included into a matrix.

It is concluded that toxicity tests with birds can be waived.
