- Deviations:
- no
- Principles of method if other than guideline:
- The adsorption coefficient (Koc) cannot be determined using the HPLC method since Standolized linseed oil does not dissolve in water, methanol and acetonitrile at a concentration of 1 g/L required for refractive index detection.
Due to its low solubility in aqueous solvents, also OECD106 is not applicable.
As an alternative, the adsorption coefficient was determined using a quantitative structure activity relationship (QSAR). - GLP compliance:
- yes (incl. QA statement)

Any other information on results incl. tables
The log Kocwas calculated using the QSAR for predominantly hydrophobics given in Technical Guidance document in support of Commission Directive 93/67/EEC on Risk Assessment for new notified substances and Commission Regulation (EC) 1488/94 on Risk Assessment for existing substances. This QSAR was used because Blown linseed oilis a hydrophobic compound:
Log Koc= 0.81 x log Pow + 0.10
The partition coefficient, Pow , of Blown linseed oil was determined to be >1x106 (log Pow > 6) using the estimation method (section 4.7). Using this log Pow value and the above given equations, log Koc of Blown linseed oil was calculated to be > 4.96.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- log Koc of Blown linseed oil was calculated to be > 4.96
