Sample tested:

other: expert statement

Parameter:

other: criteria for oxidizing properties

Remarks on result:

spontaneous ignition does not occur

Remarks:

DMDEE does not show any evidence of possessing oxidising properties, should be considered as not oxidising and should not be subjected to experimental testing

Examining the structural formula, the following observations can be made:

- The molecule does not contain any functional groups imparting oxidising properties such as organic nitro compounds, N-halogen compounds, oxohalogen compounds and interhalogen compounds.

- According to the two criteria quoted, oxidising properties can exist when:

- the electronegative atoms which are present constitute a high proportion of the molecule and are bound to elements in a high oxidation state -> in case of DMDEE the proportion of electronegative atoms in the molecule is low (3 oxygen atoms out of an overall atom count of 41). All oxygen atoms are bound to carbon atoms

- the electronegative atoms are bonded to each other or the other electronegative elements such as iodine, nitrogen, sulphur or phosphorus -> in case of DMDEE, the electronegative atoms are not bound to one another, nor to any other electronegative elements.

Assessment against these two criteria indicates strongly that the molecule will not have oxidising properties

In every respect of the oxidising liquids exemption procedure, DMDEE does not show any evidence of possessing oxidising properties.

On the basis of this exercise, the substance should be considered as not oxidising and should not be subjected to experimental testing.

Interpretation of results:

GHS criteria not met

Conclusions:

The substance is concluded not to have oxidising properties. The substance meets all criteria for exemption from testing and has a structure not at all conducive with that required to exhibit oxidising tendencies.

Description of key information

The test substance was concluded from a GLP study not to have oxidising properties following a theoretical assessment of the chemical structure (Younis 2011). 

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

The test substance does not need to be classified as an oxidising substance as based on the chemical structure the substance does not contain any chemical groups indicating oxidising properties.
