Endpoint summary
Administrative data
Description of key information
Appearance:
Based on available data from obtained report, the appearance of test chemical was determined to be solid greenish brown powder compound.
Melting point:
The Mean Melting temperature range of test chemical was determine be 262.8 - 266.3°C at 977.4 hPa.
Boiling Point:
The boiling point of test chemical was greater than 300°C at 977.4 hPa.
Density:
The mean pour density and tapped density of test chemical was determine to be 0.6904 g/cm³ and 0.7417 g/cm³ at 31 °C and 976.8 hPa.
Particle size distribution:
The particle size distribution of test item was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determine to be in the range of 150 micron to 10 micron.
Vapour pressure:
The estimated vapour pressure of test chemical at 25 deg C was 3.07E-010 Pa.
Partition coefficient:
Based on the available data from handbook, secondary source and modelling database, the octanol water Partition coefficient of test chemical was estimated to be 7.882. On the basis of this value, it is concluded that test chemical can be considered to be hydrophobic in nature.
Water solubility:
The water solubility of test chemical was determined to be less than 0.0007 mg/l at 20 °C.
Surface tension:
The study does not need to be conducted because water solubility of test chemical is below 1 mg/L at 20°C.
Flash point:
The mean flash point of test chemical was 224.3°C at pressure 977.4 hPa.
Auto flammability:
Test chemical did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that test chemical is not auto-flammable.
Flammability:
Test chemical does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that test chemical is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus test chemical was considered non-flammable.
Explosiveness:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties. In accordance with column 2 of Annex VII of the REACH regulation, the study does not need to be conducted since there are no chemical groups associated with explosive properties present in the given test chemical. Thus, this end point was considered for waiver and the chemical is considered to be "Non explosive".
Oxidizing properties:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
pH:
The pH determination of test item was done following OECD guideline 122. pH of 1% w/v solution was measured with the help of pH meter and it was observed to be 6.97 at 27.4 °C.
Viscosity:
The study does not need to be conducted because the substance is a solid. In accordance with Section 2 of REACH Annex XI, this study cannot be conducted on solid materials or gases. According to ECHA Chapter 7 guidance, viscosity measurement is only relevant to liquids and the given test substance is a solid substance. Hence this study is considered for waiver.
Additional information
Appearance:
Appearance of test chemical was determined to be solid greenish brown powder compound.
Based on available data from obtained report, test chemical is observed to be low dusting microgranulate solid in appearance.
Melting point:
The melting point determination of test chemical was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and Mean Melting temperature range was determine to be 262.8 -266.3°C at 977.4 hPa.
Boiling Point:
The boiling point determination of test chemical was done following OECD Guideline 103 and according to the method of Siwoloboff. no string of bubbles were observed upto 300 deg C, inferring boiling point to be greater than 300 deg C at 977.4 hPa.
Density:
The density of test item was determined following OECD Guideline 109 and according to the Test methods: Pour density and tapped density of powders” recommended in The International Pharmacopoeia, Fourth Edition, 2014 using bulk density apparatus.The mean pour density and tapped density of test item was determine to be 0.6904 g/cm³ and 0.7417 g/cm³ at 31 °C and 976.8 hPa.
Particle size distribution:
The particle size distribution of test item was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determine to be in the range of 150 micron to 10 micron.
Vapour pressure:
Modified Grain method was used to estimate the vapour pressure of test chemical using MPBPVP v1.43 of EPISUITE.
The estimated vapour pressure of test chemical at 25 deg C was 3.07E-010 Pa.
Partition coefficient:
Based on the available data from handbook, secondary source and modelling database, the octanol water Partition coefficient of test chemical was estimated to be 7.882.
Additional study from modelling database indicates that the octanol waterpartition coefficient (log Pow) value of the test chemical was estimated to be 7.71.
Thus, based on the available information, the logPow valueof the test chemical ranges from 7.71 to 7.88, respectively. On the basis of this value, test chemical can be considered to be hydrophobic in nature.
Water solubility:
Determination of the Water Solubility of test chemical was done according to OECD Guidelines, with the help of Column elution method. The water solubility was determined to be less than 0.0007 mg/l at 20 °C.
Hence based on the experimental value test chemical was considered to be insoluble in water.
Other supporting data also determined water solubility of test chemical were different values as 0.004–0.006 mg/L at 21 -25 °C, less than 0.0007 mg/L at 20 °C and 0.0017 mg/L at 20 °C respectively.
Based on the above all experimental and estimated values test chemical was considered to be insoluble in water.
Surface tension:
The study does not need to be conducted because water solubility of test chemical is below 1 mg/L at 20°C.
Flash point:
The flash point determination of test chemical was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was determine to be 224.3°C at pressure 977.4 hPa.
Auto flammability:
Test chemical did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that test chemical is not auto-flammable.
