Description of key information

Sodium formate is readily biodegradable.

According to OECD 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, given that the degradation potential in seawater is normally lower than in freshwater degradation tests (OECD, 2002). Sodium formate achieved 86% degradation (ThOD) over 28 days in a reliable OECD 306 study and can therefore be regarded as readily biodegradable (KM Lab, 1998).
