Description of key information

15 mg/L at 20°C, pH 2 (all constituents)
0.6 mg/L at 20 °C, pH 2 (two major constituents)
(Dinwoodie NB, Pine Chemicals Association, 2003)

Key value for chemical safety assessment

Additional information

The chromatograms resulting from Fatty Acids, C16-18 and C18 Unsaturated, Branched and Linear samples extracted from water show a different profile of peaks to those derived from the method standards (dissolved in solvent). The additional peaks found in the water extracts are likely to be components of significantly greater solubility than, or degradents from, the component used in the method quantification. These more soluble components are present at low to trace levels in Fatty Acids, C16-18 and C18 Unsaturated, Branched and Linear.

The water solubility of Fatty Acids, C16-18 and C-18, Unsaturated, Branched and Linear, measured as the sum solubility of all the components of the test material was estimated to be 15.0 mg/L at 20°C. However, the water solubility based on its two major constituents is 0.6 mg/L at 20°C.
