Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: PFW100113
- Analytical purity: 99.3% (by GC)

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: the sample is stored in cool, well-ventilated storage area prior to testing.

OTHER SPECIFICS:
- Name of test material (as cited in study report): Jeffcat DMDEE
- Physical state: Liquid
Atm. press.:
102.5 kPa
Decomposition:
yes
Decomp. temp.:
200 °C

The sample began to discolour to yellow at 200°C, this is believed to be decomposition. At 250°C, the sample still had not boiled but had darkened to brown. Observations were identical in the duplicate measurements.

Conclusions:
The substance starts to decompose at 200 °C. The measurements were taken at a pressure of 102.5 kPa.

Description of key information

In a GLP study according to test method EU A.2, the test substance was determined to decompose at and above 200°C (Younis, 2011).

Key value for chemical safety assessment

Additional information

The substance was concluded to decompose before boiling.
