The reported Octanol-Water Partition Coefficient range (log Kow) is given under the assumption that the sample is mainly consisting of oleic acid and oleic acid methyl ester. The data were taken from the software data base KOWWIN (version 1.68) of the U.S. Environmental Protection Agency.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
