Appendix A: Physical and Chemical Properties -20 ± 0.5 °C Freezing Point ˂ OECD TG 102 Melting Point/Melting Range. EC Council Regulation No 440/2008 A.1 Melting/Freezing Temperature. Remarks The test material remained unchanged in appearance during cooling. The freezing temperature was determined to be < 253 ± 0.5 K (-20 ± 0.5 C) Firmenich (2013) 232 ± 2 °C at 97.9 kPa Boiling Point OECD TG 103 Boiling Point. EC Council Regulation No 440/2008 A.2 Boiling Temperature. Remarks Siwoloboff method. Firmenich (2013) 0.994 at 20 C Relative Density OECD TG 109 Density of Liquids and Solids. EC Council Regulation No 440/2008 A.3 Relative Density. Remarks Oscillating density meter method was used. The apparatus was calibrated using toluene and trichloroethylene as reference standards. Firmenich (2013) 0.0016 kPa at 20 C Vapour Pressure 0.0028 kPa at 25 °C OECD TG 104 Vapour Pressure. EC Council Regulation No 440/2008 A.4 Vapour Pressure. Remarks Isothermal thermogravimetric effusion method. WIL Research Europe B.V (2013a) < 1 g/L at 20 °C Water Solubility OECD TG 105 Water Solubility. EC Council Regulation No 440/2008 A.6 Water Solubility. Remarks Flask Method The concentration of test substance in the sample solutions was determined by high performance liquid chromatography (HPLC). Firmenich (2013) Stable at pH 2-12 Hydrolysis as a Function of pH OECD TG 111 Hydrolysis as a Function of pH. The notified chemical was added in the pH buffers (at pH 2, 5, 7, 8.5 and 12) to reach concentrations in the range of 200 - 300 ppm. The mixtures were then kept in an oven at 40 °C. Small aliquots of the test solutions were extracted using an organic solvent containing a hydrocarbon standard on a regular basis throughout the test. The extracts were analysed by gas chromatography. pH T (°C) t½ ( days) 2 40 > 365 5 40 > 365
