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)

Remarks on result:
other: QSAR

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
