Adsorption / desorption
Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption: screening
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter

Description of key information
Adsorption/desorption (Cyrene™/Gem Diol): Low potential for adsorption
Key value for chemical safety assessment
- Koc at 20 °C:
- 1.7
Additional information
The substance has low log Kow value (<3) and thus has low potential for adsorption, and the requirement for testing is waived.
For environmental exposure assessment, adsorption is predicted using the ‘non-hydrophobics’ log Kow-based prediction method for log Koc (Sabljic et al., 1995).
The relevant equation is:
Log Koc= 0.52 log Kow + 1.02
Therefore, log Koc for Cyrene™/Gem Diol = 0.23.
