Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The partition coefficient of Alkenes, C11-C14, hydroformylation products, distn. residues, reaction products with maleic anhydride and sodium bisulfite, sodium salts (batch: Rif. 7018) was estimated on basis of the respective solubilities in water and n-octanol according to OECD guideline 107. The solubility in n-octanol was determined following the OECD guideline 105 from 2013-04-19 to 2013-04-23 at Dr.U.Noack-Laboratorien, 31157 Sarstedt, Germany.

The partition coefficient of the test item was calculated to be log (KOW) = 4.42. The employed method, determination of individual solubility in n-octanol and water and calculation of partition coefficient, was regarded as the best feasible way for an assessment of the n-octanol / water partition coefficient, as a direct determination is not possible as no suitable detection system could be found.
