Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

-
Cas Number:
67881-98-5

Results and discussion

Water solubility
Water solubility:
> 100 000 mg/L
Temp.:
20 °C
pH:
> 4 - < 9
Details on results:
At 24 hours (at 20 degrees celsius) the test solutions had transformed into a clear solid phase of rubbery texture, with a viscous yellow liquid present on the surface. It was thought that polymerisation had occurred overnight, giving rise to the solid phase.

Any other information on results incl. tables

The pH measurements were not available from the letter of access dossier. Therefore a pH range of 4 -9 was included in this summary consistent with the environmentally relevant pH's (see EC Guidelines on environmental testing) under which these tests should be conducted.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The test substance, HEMA-PC, was determined to be very soluble, with a water solubility of >100000 mg/L
Executive summary:

Water solubility was conducted using EU Method A.6 (Water Solubility). The test substance, HEMA-PC, was determined to be very soluble, with an initial water solubility of >100000 mg/L. At 24 hours (at 20 degrees celsius) the test solutions had transformed into a clear solid phase of rubbery texture, with a viscous yellow liquid present on the surface. It was thought that polymerisation had occurred overnight, giving rise to the solid phase.
