Description of key information

The adsorption potential to soil or sediment is low. The mean logKoc = -0.054.

Key value for chemical safety assessment

Koc at 20 °C:
0.88

Additional information

The partition coefficients of sodium phenoxyacetate is low, i.e. log Pow = -2.48, see Chapter 4.7. A relevant adsorption of

sodium phenoxyacetate to soil is therefore not expected and a waiving of the study is justified, according to column 2 of Annex VIII and IX.

QSAR methods were applied to estimate the Koc.
