Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 270-737-2 | CAS number: 68477-54-3 A complex combination of organic compounds obtained by the distillation of products from a steam cracking process. It consists predominantly of unsaturated hydrocarbons having carbon numbers predominantly in the range of C8 through C12.

Description of key information
Water solubility data was available for 4 streams within this Category. Two results showed the water solubility range to be between 62 and 108 at 20 °C. One study showed The test item is water-soluble to some extend. Different results for the water solubility were found depending on the amount of test item applied. At sample sizes of c 100 mg/l (97.16 to 139.08 mg/l) water soluble fractions of c. 24% (22 to 27%) were found, at sample sizes of c. 1000 mg/L (1104.50 to 1150.00 mg/l) the water soluble fractions were found to be each c. 5%. This study appears to indicate that following equilibrium the test substance is more soluble. This is not usually the case. A further study provided a water solubility value of 0.013 g/100ml.

Additional information
68477 -40 -7: 62 mg/l at 20 °C (TNO Prins Maurits Laboratory 1989), 68477 -54 -3: 108 mg/l at 20 °C (TNO Prins Maurits Laboratory 1989), 94733 -07 -0: Water-soluble to some extent (GKA Competence Center Analytics 2007), 101316 -62 -5: 130 mg/l (TS&D Rutgers Germany 2010). These data will be read across to all category members.
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.
