Additional information

In the study from Geoffroy (2000), the vapour pressure of ITTFEP (purity 98.5%) was determined under GLP according to OECD 103 and EU A.4. The vapour pressure was determined with the gas saturation method by regression for the liquid and solid state, i.e., for 20 and 25°C as 0.66 and 1.4 Pa, respectively. The test system was checked with Dibuthylphtalate and the results were in concordance with literature data.

This information is considered to be Klimisch 1 information since this study was performed according to international guidelines and under GLP.

The obtained results are considered as relevant for the further assessment.
