Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The estimation of the surface tension value of 12-ketochenodeoxycholic acid by ACD/Labs' ACD/PhysChem Suite is 49 mN/m. Considering that 12-ketochenodeoxycholic acid is a bile acid and therefore it is a surfactant, the estimated value is consistent with the decrease of surface tension that it should produce in a water solution (water surface tension: 72.75 mN/m).
