Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Test demonstrates substance is not readily degradable. However,transformation dissolution test demonstrates that substance is slightly soluble. When dissolved, the substance dissociates in water in Ag and behenate to levels above the ecotoxicity reference value.

As inorganic substances, silver metal and inorganic silver-containing compounds will not biodegrade.

Behenate on its own is inherently degradable but degradability in the test is hampered by high free silver ion toxicity in the test medium. Read-across to behenate is however still justified due to lower Ag concentrations in environmental media.
