Additional information

In accordance with Annex VIII Column 2 of Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals, the adsorption/desorption screening test (required in Section 9.3.1) does not need to be conducted as the substance and its relevant degradation products decompose rapidly.


Despite not being a mandatory process the absorption of tetradecan-1-ol was calculated in a batch equilibrium study with sewage sludge. An adsorption coefficient of 50828 L/Kg was determined for tetradecan-1-ol in a reliable study conducted according to generally accepted scientific principles.
