Additional information
Regulation (EC) No 2037/2000 Of The European Parliament and of The Council of 29 June 2000 on substances that deplete the ozone layer lists within ANNEX I states that the substance is listed as a Group 1 substance. However, the registrant has a derogation in accordance with Regulation (EC) No 1005/2009 Of The European Parliament and of The Council of 16 September 2009 on substances that deplete the ozone layer that allows for use of the substance as a processing agent. The mentioned Regulation reports in Annex III, point e) the following derogation: "use of CFC-12 in the photochemical synthesis of perfluoropolyetherpolyperoxide precursors of Z-perfluoropolyethers and difunctional derivatives".
However, in accordance with the above two pieces of legislation, release is strictly controlled. As such, no release to the environment is envisaged, and hence it is deemed inappropriate to assess the following endpoints on the basis of no-release:
Intermittent Releases
STP
Sediment (freshwater)
Sediment (Marine)
Air
Soil
Secondary poisoning.
Indicative PNEC’s are provided for fresh and marine aquatic environments; these are based on the proposed data for the Fish, Daphnia and Algae that trigger environmental classification as:
H412: Harmful to aquatic life with long lasting effects
In practice the substance is not released, hence exposure concentrations are considered to be negligible.
Conclusion on classification
The classification was determined based on an experimental study in daphnia and predictions from validated QSAR models. The data sources have all been ranked reliability 2 according to the Klimish et al system. This ranking was deemed appropriate because the studies were either non-GLP are conducted via the use of appropriate QSARs.
Justification for classification or non classification
The above results and identified properties triggered classification under the CLP Regulation (EC No 1272/2008) as follows:
H412: Harmful to aquatic life with long lasting effects
H420: Harms public health and the environment by destroying ozone in the upper atmosphere.
