Description of key information
C15 and C16 chlorinated paraffins (51-52% chlorination, respectively) are practically insoluble in water, with values of 0.005 mg/L (parent compound) and 0.027 mg/L (radioactivity) at 20oC (Madeley et al. 1983a) and 0.010 mg/L and 0.004 mg/L (radioactivity) in freshwater and seawater, respectively, at 16-20oC (Campbell and McConnell, 1980).
Key value for chemical safety assessment
- Water solubility:
- 0.027 mg/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of a C15 chlorinated paraffin (51% chlorination) was determined by stirring 50 mg of the material, weighed on to a microscope slide, in 5 L water for 91 days. After allowing the solution to settle for 87 days to equilibrate, the concentration of test material was determined by a radiochemical method and by analysis of the parent compound by thin-layer chromatography. The water solubility determined by the two methods was 0.005 mg/L (parent compound) and 0.027 mg/L (radiochemical) at 20oC. The final RAR (EU, 2005) concluded that the solubility values determined by the two methods are in reasonable agreement, given that the test material is a complex mixture.
In support, Campbell and McConnell (1980) reported the solubility at 16-20oC of a C16 chlorinated paraffin (52% chlorinated) to be 0.010 mg/L and 0.004 mg/l in freshwater and seawater, respectively, based on radioactivity measurements. Few other details are available about the method used, but according to the RAR (EU, 2005) the results obtained are comparable with those reported by Madeley et al. (1983a).
The upper water solubility value of 0.027 mg/L will be used as representative. It is likely that the water solubility will vary with both carbon chain length and degree of chlorination.
