Additional information

ADSORPTION / DESORPTION

The registration substance has a low measured Log Kow of 1.57 and a low estimated Log Koc of 70 L/kg (EUSES 2.1). The degradation of the substance and its metabolites is described in IUCLID Ch.5.2.4 and fast degradation is likely for soil and sediment (IUCLID CH. 5.2). No stable metabolites are expected. Based on these facts a measurement of the solid water partitioning coefficients is not warranted (see also REACH Guidance Documents).

HENRY'S LAW CONSTANT (HLC)

The Henry's Law constant (HLC) can be estimated from vapour pressure and water solubility or by fragment estimation methods. EUSES 2.1 estimates a HLC of 8.4 E.06 Pa*m3/mol at 12 deg C (low volatility).

DISTRIBUTION MODELLING
For the registration substance a full Environmental Risk Assessment including distribution and exposure modelling (see CSR and IUCLID Chapter 13). As this assessment contains Confidential business information of the registrant the results are not given here but in Chapter 13.
