Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Principles of method if other than guideline:
The test protocols used to evaluate the transport and transformation of the subject chemicals have been described by Mill et al. (1982). These protocols, developed in SRI International laboratory, include hydrolysis, photolysis, and chemical oxidation in water; atmospheric chemistry; aquatic biotransformation; volatilization; and sorption of organics in sediment and soil.

Any other information on results incl. tables

No loss (<5%) of DEGDN from the aqueous phase was observed after 10 days of purging, from which was calculated Hc to be ≤ 0.02 Torr or 10-6(dimensionless). The value calculated from the aqueous solubility (0.020 M) and vapour pressure (0.0059 Torr) at 25°C is 0.30 torr/M. These low values of Hc indicate that volatization will be extremely slow in the environment.

Applicant's summary and conclusion

Conclusions:
Thelow value of Hc indicates that volatization will be extremely slow in the environment.
