Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

RESULTS OF SUPPLEMENTARY EXPERIMENT (if any):
Using the predictive fragment constant methodology software, PCKOCWIN, version 1.66, © 2000 US Environmental Protection Agency, the adsorption coefficient of the main component of the test material, barium di(bistridecylsulfosuccinate), was estimated to be log10 Koc 5.75.

Applicant's summary and conclusion

Validity criteria fulfilled:
not specified
Conclusions:
Using the predictive fragment constant methodology software, PCKOCWIN, version 1.66, © 2000 US Environmental Protection Agency, the adsorption coefficient of the main component of the test material, barium di(bistridecylsulfosuccinate), was estimated to be log10 Koc 5.75.
Executive summary:

Adsorption Coefficient. No determination of the adsorption coefficient was possible by the HPLC estimation method, Method C19 of Commission Directive 2001/59/EC. The method is not valid for surface active materials or organic acids (the barium di(bistridecylsulfosuccinate) would act as its parent acid once in aqueous solution and dissociated). Using the predictive fragment constant methodology software, PCKOCWIN, version 1.66, © 2000 US Environmental Protection Agency, the adsorption coefficient of the main component, barium di(bistridecylsulfosuccinate), has been estimated to be log10Koc5.75.
