Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

readily biodegradable

Additional information

No reliable experimental data exists for calcium diformate. There is one not assignable study available (OECD 301D; Bayer AG cited in BUA, 1991), which showed the good biodegradability of calcium diformate. The ready biodegradability criterion was passed, but no conclusion on the 10 -day window can be drawn. Therefore a read across to sodium formate was performed.

According to the REACH Guidance, when a chemical attains more than 60% ThOD or more than 70% DOC removal in a Biodegradability in Seawater test (OECD 306), it can also be expected to fulfil the criteria for ready biodegradability. Therefore, sodium formate and hence calcium diformate can be regarded as readily biodegradable (KM Lab, 1998).
