Adsorption / desorption
Administrative data
- Endpoint:
- adsorption / desorption: screening
- Type of information:
- (Q)SAR
- Adequacy of study:
- other information
- Study period:
- 20 Aug 2020
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, and documentation / justification is limited
- Justification for type of information:
- Koc result has been reported to regulatory agencies. This study summary was prepared to acknowledge the result. The model appears to be a valid QSAR based on examination of model documentation. However, the training set includes only a limited number of substances with trifluoromethyl functionality and none with higher perfluoroalkyl functionality. The applicability was not determined.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- MeFBSA has an estimated Koc of 1070 L/kg
- Executive summary:
Adsorption/desorption coefficient of MeFBSA was calculated using KOCWIN v2.00 software within Episuite v.4.11. This result has been reported to other jurisdictions. The model appears to be valid, but an examination of model training set shows no similar substances. In particular, fluorinated compound representation in the training set compounds is limited to a small number of trifluoromethyl-derived substances, apparently pesticides. The model appears reliable, but its applicability to this substance has not been demonstrated and the result is presented as such. Reliability is not assignable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
