Ethene, 1,2-dichloro-1-fluoro-2-(trifluoromethoxy)-

Oxidising properties

Link to relevant study record(s)

Reference

Endpoint:

oxidising liquids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied

the study does not need to be conducted because the substance is flammable

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING

As reported in the REACH Guidance on Information Requirements and Chemical Safety Assessment- Chapter R7a, experience with oxidising substances has provided us with a list of chemical groups and elements that are known to confer oxidising properties.
(Table R.7.1 -29 is reported as attachment).
In general terms, one can perform a screening procedure to filter out substances that are unlikely to be oxidising and for which testing can be waived. For organic substances (with the exception of peroxides) testing does not need to be carried out for substances if:
- The substance does not contain oxygen, fluorine or chlorine; or
- The substance contains oxygen, fluorine or chlorine and these elements are chemically bonded only to carbon - Inorganic substances that do not contain oxygen of halogens do not need to be tested. If the screening procedure identifies the material as having potential oxidising properties, or there is any doubt, then, in the interests of safety, testing should be carried out.

Assessment:
The substance 1,2-dichloro-1-fluoro-2-trifluoromethoxy-ethene is an organic compound which contains oxygen, fluorine and chlorine and these elements are chemically bonded only to carbon.
Furthermore, the substance does not contain any of the chemical groups known to confer oxidising properties as reported in the attached table R.7.1 -29 .
Therefore, according to the screening criteria reported in the REACH Guidance on Information Requirements and Chemical Safety Assessment - Chapter R7a, basing on the chemical structure, it can be concluded beyond a reasonable doubt that 1,2-dichloro-1-fluoro-2-trifluoromethoxy-ethene does not possess oxidising properties.

Furthermore, the experimental value for flash point indicates the substance is flammable cat.3.

Interpretation of results:

GHS criteria not met

Conclusions:

Basing on the chemical structure, 1,2-dichloro-1-fluoro-2-trifluoromethoxy-ethene does not contain alerts for oxidising properties.

Executive summary:

The oxidising properties of 1,2-dichloro-1-fluoro-2-trifluoromethoxy-ethene were evaluated according to the screening procedure described in the REACH Guidance on Information Requirements and Chemical Safety Assessment- Chapter R7a where a set of criteria is described to identify materials being potential oxidiser.

As reported in the Guidance, experience with oxidising substances has provided us with a list of chemical groups and elements that are known to confer oxidising properties. Furthermore, for organic substances (with the exception of peroxides) testing does not need to be carried out for substances if:

o The substance does not contain oxygen, fluorine or chlorine; or

o The substance contains oxygen, fluorine or chlorine and these elements are chemically bonded only to carbon.

 

The substance 1,2-dichloro-1-fluoro-2-trifluoromethoxy-ethene is an organic compound which contains oxygen, fluorine, chlorine and these elements are chemically bonded only to carbon, furthermore the substance does not contain any of the chemical groups known to confer oxidising properties.

Therefore, according to the screening criteria reported in the REACH Guidance on Information Requirements and Chemical Safety Assessment- Chapter R7a, basing on the chemical structure, it can be concluded beyond a reasonable doubt that 1,2-dichloro-1-fluoro-2-trifluoromethoxy-ethene does not possess oxidising properties.
