Materials and methods
Test guidelineopen allclose all
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
- Guideline:
- other: REACH guidance on QSARs R.6, May 2008
- Principles of method if other than guideline:
- Because the test item was expected to have a log Pow lower than 0, the shake-flask method should be used for the determination of the log Pow of Red VP2298. During Non-GLP-Pre-Tests buffer solutions of test item with concentration 1 g/L with pH 2, pH 4 and pH6 were shaken with 1-octanol. Each buffer-phase was coloured, all 1-octanol-phases were uncoloured. Spectra were recorded using a photometer (190 – 1100 nm). The buffer solutions showed an absorption maximum at 529 nm, the 1-octanol-phases did not show any absorption at 529 nm. It is thus concluded, that the concentration of Red VP2298 in the 1-octanol-phase is not determinable using a photometric method. Therefore a calculation of the log Pow was recommended by the study director.
For the calculation of the log POW the program KOWWIN 1.68 (US EPA 2012 Estimation Programs Interface Suite™ for Microsoft® Windows, v 4.10. United States Environmental Protection Agency, Washington, DC, USA) was used. - GLP compliance:
- no
