Description of key information

The Log Pow of the test substance has been determined by the sum of the Log Pow contribution from its major components. The Log Pow has been determined to 0.0 at 25°C at pH 5. Furthermore, a calculation of the Log Pow has been performed using EPIsuite v4, which yields the same results as the measured value.

Additional information

The Log Pow of the test substance has been determined by the sum of the Log Pow contributions from its major components.The Log Pow has been determined to 0.0 at 25°C at pH 5 with a starting concentration of 1% of the critical micelle concentration (CMC) in water. However, the value of Log Pow is the same upon addition of concentrations at 1 and 10% of the critical micelle concentration (cmc) into the water rich phase, where the 10% of the cmc was turbid and the 1% of cmc was not (visually). Although, it is worth mentioning that the avaliable guidelines are not applicable for surfactants, according to guideline OECD 123, the test substance should be added in the octanol rich phase. Nontheless, a calculation of the Log Pow has been performed using EPIsuite v4, which yields the same results as the measured value.
