Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 water solubility of n-dodecenyl succinic anhydride (nDDSA) was attempted to be determined experimentally by several methods. One method (EI-GC/MS) verified that the concentration of nDDSA was over 20 mg/L in pH 7 aqueous buffer with 0.6% acetone (as cosolvent) at 25 °C The maximal solubility without cosolvent was estimated to be 10 mg/L for the purposes of further studies on hydrolysis, but actual water solubility may be lower. The water solubility was estimated using ACD Labs software to be 0.13 mg/L at 25 °C and pH of 7.
