Additional information

The partition coefficient of Sulfosuccinate of C18-22 Alkyl-Alcohol 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.
The water solubility was determined in a separate study at 375±25 µg/L .
The n-octanol solubility of the test item was determined using the flask method at 20 ± 0.5 °C with preincubation at 30 ± 0.5 °C.

The solubility in n-octanol used to calculate the partition coefficient was estimated on basis of the sum of the peak area of each of the three components and was determined to be 180±64 mg/L.

The partition coefficient of Sulfosuccinate of C18-22 Alkyl-Alcohol was estimated to be:

KOW= 612

Log(KOW) = 2.79
