Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption, other
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- See attached QPRF and QMRF
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- No guideline available, QSAR conduted according to REACH guidance on information requirements and chemical safety assessment, chapter R.6: QSARs and grouping of chemicals, May 2008.
- GLP compliance:
- no
- Specific details on test material used for the study:
- CC(CCCCCC\C=C\CCCCCCCC([O-])=O)OC1OC(CO)C(O)C(C)C1OC1CC(CO)C(O)C(O)C1O
The substance is a complex mixture of variable composition. It is therefore scientifically not justified to determine the Koc by experimental methods. Therefore, the Koc was calculated using the software EPISuite (US EPA) for each relevant sophorolipid constituent. The highest Koc obtained by calculation was taken as the representative for the substance. - Key result
- Type:
- log Koc
- Value:
- 4.46
- Remarks on result:
- other: The Koc may vary by pH. The estimated value is applicable to the neutral pH range.
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The highest log Koc for the test item is 4.46, predicted for the constituents by QSAR, KOCWIN v2.00 software.
- Executive summary:
The log Koc of Sophorolipids: fermentation products of glucose and fatty acids, C18 (unsaturated), glycerol esters with yeast Starmerella bombicola, hydrolysed was estimated to be 4.46 using the QSAR model KOCWIN v2.00 leading to an estimated Koc of 29000 L/kg.
Reference
KOCWIN predicted that Sophorolipids: fermentation products of glucose and fatty acids, C18 (unsaturated), glycerol esters with yeast Starmerella bombicola, hydrolysed has a log Koc of 4.46
Description of key information
The highest log Koc for the test item is 4.46, predicted for the constituents by QSAR, KOCWIN v2.00 software.
Key value for chemical safety assessment
- Koc at 20 °C:
- 29 000
