Description of key information
Additional information
Appearance/physical state/colour
Olaflur is a yellow-brown, wax-/fat-like mass with a nut-like odour.
Melting/Freezing Point
The melting point of Olaflur was evaluated to be 12.7°C i.e. 285.85 K, the freezing point to be 9.3°C i.e. 282.45, respectively, using differential thermal analysis.
Boiling Point
Olaflur decomposes as observed in TGA (Thermogravimetric analysis) analysis before boiling. Consequently, a boiling point cannot be determined.
Density
The density was calculated by determination of the mass of the substance in a calibrated pycnometer. In order to fill the substance into the pycnometer, it had to be heated to about 40°C (due to its high viscosity). Three separate tests were made. The density of Olaflur was determined to be 0.97 +- g/mL at 21°C. The significant uncertainty of the value results from some small air bubbles which could not be removed from the pycnometer without excessive heating of the substance.
Granulometry
According to European Commission Regulation 1907/2006 Annex VII, Section 7.14, the particle size distribution (granulometry) does not need to be determined if the substance is marketed or used in a non solid or granular form. Olaflur is a fat-like resp. wax-like mass marketed as component of pastes or fluids only. Thus, the study on particle size distribution is not required.
Vapour pressure
The vapour pressure of Olaflur was estimated based on the free base as evaluation technically not applicable for a salt.
For the multi-constituent substance Olaflur a vapour pressure range was estimated on basis of the SMILES codes for the shortest fatty amine chain myristil (R= C14H29) as lower limit value (worst case approach), as well as for the longest fatty amine chain stearyl (R= C18H37) as upper limit value. Using the estimation program MPBPWIN v.1.43, part of EPIWIN, at 25°C a vapour pressure in the range of 4.21E-014 to 5.58E-016 mbar was derived based on the Modified Grain Method.
This result is in line with the interpretation of the experimental data estimating a vapour pressure value for the solvent-free Olaflur using a modified static method.
Partition coefficient
The log Pow of Olaflur was determined in replicate for three different ratios of n-octanol and water. The six determined log Pow values do not fall within a range of 0.3 but 0.5 units. Therefore, the test did not pass the validity criterion. However, the test was difficult to evaluate, since a micellous layer was formed at the interface between octanol and water.
Based on the results obtained, the log Pow value was calculated to be 0.62 (standard deviation: 0.41 log units).
Assuming that the test substance fraction that is not dissolved in water is completely dissolved in the octanol phase (worst case estimation), i.e. ignoring the micellous layer, a log Pow value of 1.94 results (standard deviation: 0.29 log units).
Water solubility
In a preliminary test optically good water solubility was observed until 100 mg/L. At 500 g/L the test substance had a gelatinous appearance. Based on this result obtained it was decided to test 200 g/L as highest concentration in the main study.
The water solubility of Olaflur was investigated by dissolving the test substance at 30 ± 0.5°C for at least 24 h and equilibration at 20 ± 2°C for again 24 h, both by using a magnetic stirrer. The water solubility of Olaflur was determined to be stable after 24 h.
The initially added amounts of test substance were 200, 100 and 50 g per L deionised water. Based on the measured concentrations, the water solubility was determined to be 164 g/L at 20 ± 2°.
Surface tension
The surface tension of Olaflur at 20°C was determined to be 43.6 mN*m-1 using a concentration of 1g/L. According to EU method A.5 for the determination of the surface tension, substances showing a surface tension lower than 60 mN/m under the conditions of this method should be regarded as surface-active materials. This also explains the difficulties to determine a reliable log Pow.
Flash point
The flash point of Olaflur was determined to be 55°C indicating that the partial pressure of flammable vapour (ethanol) above the substance at this temperature is high enough to produce a flammable mixture with air. In general, substances and mixtures having a flash point at or below 55°C have to be classified as hazardous substances (R10), and as hazardous good for transport (class 3). However, as no sustainable burning, i.e. no fire point, was observed, no classification is required.
Auto flammability
The auto ignition temperature of Olaflur was determined to be 400°C (i.e. 673.15 K), the auto-ignition temperature of solvent-free Olaflur was determined to be 390°C (i.e. 663.15 K).
Flammability
As test substance Olaflur is a fat-like resp. wax-like mass, determination of the flammability was not carried out. Instead the flash point according to the European Commission Regulation 1907/2006, Annex VII, Section 7.11., was evaluated.
Considering the chemical structure of Olaflur there are no groups associated with flammability properties and/or pyrophoric properties, further experience in handling and use does not indicate flammability upon contact with water and/or pyrophoric properties. Thus, the experimental test to determine whether the reaction of a substance with water or damp air leads to the development of dangerous amounts of gas or gases, which may be highly flammable, according to test guideline A.12, as well as the determination of pyrophoric properties according to test guideline A.13 of European Commission Regulation 1907/2006, was replaced by a theory based evaluation.
Explosiveness
Based on the molecular structure of the substances, explosive properties can be excluded. Thus, a test on explosive properties with Olaflur was not performed.
Oxidising properties
The test on oxidising properties with Olaflur was not performed. Based on the molecular structure of the substances, and as the fluorine is only present as counter ion, oxidising properties can be excluded.
Stability in organic solvents and identity of relevant degradation products
Olaflur is a fat-like resp. wax-like mass marketed as component of water based pastes or fluids only – organic solvents are not used. Thus, the study on stability in organic solvents and identity of relevant degradation could be omitted as not relevant.
Dissociation Constant
As no distinct pH-steps could be identified, the pK values were determined using numerical fitting, resulting in a pK1 = 7.8 and a pK2 = 6.5.
Viscosity
The dynamic viscosity of Olaflur was determined to be 56 Pa s at 20°C and 24 Pa s at 40°C, respectively.
