Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Water solubility
Water solubility:
< 1.2 mg/L
Temp.:
27.2 °C
pH:
6
Details on results:
TOC analysis was performed. Two experiments were performed. Only in one experiment, first sampling, a TOC concentration could be measured. At all other sampling times the TOC was below the limit of quantification.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): other: insoluble or slightly soluble
In a study according OECD Test Guideline 105, the water solubility of the test substance was determined to be < 1.2 mg/L (at approx. 27°C)
Executive summary:

In a preliminary study, the solubility of the test substance in water was estimated as < 10 mg/L.

The test item was filled into a HPLC column. A flow rate of 25 ml/h was set. After discarding the first 375 ml, fractions were collected

and measured. Six samples at the flow rate 25 ml/h were measured by DOC-analysis. Flow rate was decreased to 12.5 ml/h and another twelve fractions were collected and measured.

Except for the first fraction, all fractions showed values below the limit of quantification of the anlaytical method (< 1.0 mg/L TOC):

The carbom content in the original test item was 80.35 %, whereas in the sampled fractions, no carbon could be found.

Therefore, the test item is virtually insoluble in water.

Considering the detection limit of the analytical method and the carbon content in the test item, the solubility of the test item is stated as < 1.2 mg/L at 27.7 - 27.2 °C.
