Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Preliminary study:
Not applicable.
Transformation products:
not measured
Dissipation DT50 of parent compound
Remarks on result:
not determinable because of methodological limitations
Details on results:
No determination was possible by Method 111 of the OECD Guidelines for Testing of Chemicals, 12 May 1981 due to the negligible solubility of the test material in water, 1.36 x 10-3 g/l of solution. Secondly and more critically, the test material found in solution during the water solubility study represented only the lower molecular weight range of the test material components. Therefore working at half this water solubility value, the maximum concentration permitted by the method guideline, was not applicable since the value does not address the more abundant, higher molecular weight fraction of the test material.

Applicant's summary and conclusion

A hydrolysis study according to OECD 111 was not possible due to the low and incomplete solubility of the test material.
Executive summary:

A study was attempted according to OECD guideline 111. However due to the low and incomplete solubility of the test material the test could not be performed.
