EC number: 203-347-8
CAS number: 105-95-3
In pure water: 14.8 mg/L (at 20°C, equilibrium after ca 6 days)In reconstituted natural (daphnia) medium: ca 6.6 mg/L (up to 16.0 mg/L measured if prolonged contact time)Considered as slightly soluble.
A GLP experimental study was conducted, according to the standard
OECD/EC flask method. However results did not lead to a plateau.
Therefore, a new study was run with more precautions (slow-stirring from
above, dark conditions), and in both pure water and reconstituted
daphnia medium. It is considered as key. Equilibration time was similar
in both medium, with half lower concentration in
daphnia medium. However a two-step solubilisation phase was observed if
prolonged contact with daphnia medium, leading to similar final
concentrations, but this was not considered to be
relevant value for ecotoxicity studies and environmental assessment.
The standard result (i.e. in pure water) was retained as key value for
purpose of CSA.
