The melting point of Quaternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates determined by differential scanning calorimetry (OECD guideline 102, adopted 27th July 1995 and EU method A.1, 30 May 2008) is reported to be 45°C at 101.3 kPa (partial melting at -45 °C resp. 45 °C (main component). The boiling point of Quaternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates determined by differential scanning calorimetry (OECD guideline 103, adopted 27th July 1995 and EU method A.2, 30 May 2008) is reported to be 294°C at 101.3 kPa. The densityof Quaternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates determined by gas displacement pycnometry (OECD guideline 109, adopted July 27, 1995 and EU method A.3, 30 May 2008) is reported to be 0.972 g/cm³ at 20°C. In accordance with column 2 of REACH Annex VII 7.14, a study on granulometrydoes not need to be conducted if the substance is marketed or used in a non solid or granular form: The substance is marketed as waxy flakes or pellets. The vapour pressure of Quaternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates determined by the vapour pressure balance (effusion method) according to OECD guideline 104 (adopted 27 July 1995) and EU test method A.4 (30 May 2008) is reported to be < 2 hPa at 20°C. According to OECD guideline no. 117 (adopted on 13 April 2004] and EU test method A.8 [Council Regulation (EC) No 440/2008 of 30 May 2008; with the HPLC method] the weighted average log Kow was 3.1 at 25.0 °C ± 0.2 °C. The water solubility of Quaternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates was determined according to OECD guideline 105, 27 July 1995, using the flask method. The water solubility of Quaternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates is 485 mg/L at 20°C (pH 4.095). The surface tension of Quaternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates was determined according to OECD 115, using the ring method. The surface tension of Quarternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates was determined to be 30.8 mN/m at 1 g/L. The flash point of Quaternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates was analysed by the Pensky-Martens closed cup method (EU method A.9, 30 May 2008). No flash point could be determined. According to REACH regulation Annex VII, 7.12, column II, a test on auto flammability does not need to be conducted for solids with a melting point below 160°C. The melting point of the test substance is 45°C. The flammability of Quaternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates was analysed according to the EU test method A.10 (30 May 2008). In the preliminary test no ignition of the substance was observed. According to the guideline the execution of the main test was not necessary. The test substance is not highly flammable. Explosive properties testing does not need to be conducted as there are no chemical groups associated with explosive properties in the molecule. Oxidising properties testing does not need to be conducted on the basis of chemical structure. According to REACH Annex IX, 7.15, column 1, a study on stability in organic solvents is only required if stability of the substance is considered to be critical.
