The column elution method was used to determine the water solubility of
Phytosphingosine and was based on the following guidelines:
OECD guideline for testing of chemicals no. 105: "Water Solubility",
Adopted July 27, 1995. EEC Directive 92/69 EEC, Part A, Methods for the
determination of physico-chemical properties, A.6: "Water solubility".
EEC Publication no. L383, December 1992. Several attempts were made to
determine the water solubility of Phytosphingosine accurately. The
results are shown in the table.
Based on these results it was decided to report water solubility of
Phytosphingosine to be between 1.4x10^-3 and 3.8x10^-3 g/1 at 20.0 ±
The water solubility of Phytosphingosine at 20.0 ± 1.0°C was measured to
be between 1.4x10^-3 and 3.8x10^-3 g/L, using the column elution method.
The geometric mean is 2.6 mg/L.
