Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
In a GLP study based on OECD Guideline 105, the water solubility of a [6-14C]-labelled C12 chlorinated parraffin (59% chlorination) was determined to be 0.47 mg/L (based on analysis of total radioactivity) at 20oC using a modified flask method. This result may have been affected by the partial degradation of the chlorinated paraffin during the study (Madeley and Gillings, 1983).
Key value for chemical safety assessment
- Water solubility:
- 0.47 mg/L
- at the temperature of:
- 20 °C
Additional information
In a GLP study based on OECD Guideline 105, the water solubility of a [6-14C]-labelled C12 chlorinated parraffin (59% chlorination) was determined using a modified flask method. The solubility of the test material was determined by stirring 50 mg of the material, weighed onto a microscope slide, in 5 L water for 91 days. After allowing the solution to equilibrate (no stirring) for a further 87 days, the concentration of test material was determined by radiochemical analysis and by thin-layer chromatography. The solubility was estimated by the two methods to be 0.15 mg/L (based on analysis of parent compound) and 0.47 mg/L (based on analysis of total radioactivity) at 20oC. These results may have been affected by the partial degradation of the chlorinated paraffin during the study (Madeley and Gillings, 1983).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
