Additional information

Ethanethiol has a reported log Kow value of 1.5. Testing for adsorption/desorption is therefore waived in accordance with Column 2 of REACH Annex IX on the grounds that the substance has low potential for adsorption onto organic carbon in soil and sediment.

An estimated log Koc value of 1.11 has been obtained using an appropriate calculation method.
