Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility of CAS 68951-72-4 was determined to 0.2 mg/L at 20 C and pH 9.3
Executive summary:

The water solubility of CAS 68951-72-4 was determined to 0.2 mg/L at 20 C and pH 9.3

Description of key information

The water solubility, expressed as the critical micelle concentration (CMC), is 0.2 mg/L at 20 °C.

Key value for chemical safety assessment

Water solubility:
0.2 mg/L
at the temperature of:
20 °C

Additional information

Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 0.2 mg/L (pH 7, 20 °C).


 


In addition, the water solubility of the registered substance is estimated using the WATERNT model, the water solubility is 0.48 mg/L, calculated from its major constituents.
