Note: Log Pow values for the reference substances are mentioned in OECD
A log Pow range of 1.6-3.3 was determined for the substance PEMP
product. The log Pow was determined using the HPLC method in a GLP study
according to EC A.8, OECD 117 and OPPTS 830.7570. The mobile phase was
75/25 (v/v) methanol/buffer pH 6 and the wavelength of detection 210 nm.
Duplicate measurements were performed. Both chromatograms of the test
substance solution (500 mg/L) showed four substance peaks with areas
ranging from 3.0% to 66%. The log Pow value for the peaks with areas of
66%, 23%, 7.9% and 3.0% was determined to be 2.7, 1.6, 3.3 and 2.2, resp.
Log Pow range: 1.6-3.3 (EC A.8, OECD 117 and OPPTS 830.7570: HPLC
The chromatogram of the test substance solution (500 mg/L) showed four
substance peaks with areas ranging from 3.0% to 66%.
The maximum value of the log Pow range was chosen as the key value for
CSA (worst-case approach).
