Adsorption / desorption
Administrative data
- Endpoint:
- adsorption / desorption
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Data estimated by KOCWIN v2.00 which uses a valid calculation method; the test substance was found to fall in the applicability domain of this method and results were adequate for the purpose of classification and labelling and/or risk assessment.

Results and discussion
Any other information on results incl. tables
The estimated soil adsorption coefficients (log Koc) of C18:0 triglyceride and the adduct formed by two C18:3 triglycerides using KOCWIN v.2.00 (EPIWEB v.4.1) were found to be ca. 14 and 25, respectively.
Applicant's summary and conclusion
- Conclusions:
- The estimated soil adsorption coefficients (log Koc) of C18:0 triglyceride and the adduct formed by two C18:3 triglycerides using KOCWIN v.2.00 (EPIWEB v.4.1) were found to be ca. 14 and 25, respectively.
- Executive summary:
The soil adsorption coefficient (log Koc) of castor oil, dehydrated was estimated by the KOCWIN v.2.00 model of EPIWEB v.4.1 (as shown in the table below) considering the potentially lowest and highest adsorbing components present in the substance, i.e. a C18:0 triglyceride and an adduct formed by two C18:3 triglycerides. The log Koc was found to range between ca. 14 and 25, suggesting that castor oil, dehydrated would tend to strongly bind to soil and sediment.
