Administrative data
Description of key information
Appearance:
The appearance of Test item is observed to be white fine powder organic compound.
Melting point:
The melting point of test chemical was determine be greater than 360°C at 975.6hPa.
Boiling Point:
The study does not need to be conducted because the substance is a solid which melts above 300°C. The study does not need to conducted because the given test chemical is a solid substance which melts above 300°C i.e greater than 360°C. hence present study is considered to be waiver.
Density:
The mean pour density and tapped density of test chemical was determine to be 0.5561 g/cm³ and 0.8002 g/cm³ at 26°C and 974.4 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 53 micron.
Vapour pressure:
The study does not need to conducted because the melting point of given chemical Disodium succinate (CAS No. 150-90-3) is above 300°C i.e greater than 360°C. hence present study is considered to be waiver.
Partition coefficient:
Based on the available data from handbook and secondary source, the partition coefficient (log Pow) value of the test chemical was determined to be < -0.59. On the basis of this value, test chemical can be considered to be hydrophilic in nature.
Water solubility:
The water solubility determination of test item was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determine to be 455760 mg/L at 25°C.
From this solubility value it is concluded that test chemical is very soluble in water.
Surface tension:
The study does not need to be conducted because surface activity is not a desired property of the material. Test chemical finds major use as a seasoning agent and also as a food additive. Thus, in accordance with column 2 of Annex VII of the REACH regulation, this study was not conducted since surface activity is not a desired property of the chemical.
Flash point:
The mean flash point of test chemical was 103°C at 976.6 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 as 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.
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 as per the test guideline OECD 122. The mean pH of the test solution was determined with the help of digital pH meter. The mean pH was determine to be 8.59 at 26 °C.
Additional information
Appearance:
Based on available data from obtained report, the appearance of Test item is observed to be white fine powder organic compound.
Other supporting data from authoritative database and handbook, the also supported the selected key study and observed the appearance of test chemical as odorless white crystalline powder organic compound.
Melting point:
The melting point determination of test item was done following OECD Guideline 102 and according to the metal block capillary method. no change was observed in state of test item upto 360 deg c, inferring melting point to be greater than 360 deg C at 975.6 hPa.
Other supporting data from authoritative database and another report, also supported the selected key study and exhibited themelting point of test substance is greater than 300°C and greater than 400°C.
Boiling Point:
The study does not need to be conducted because the substance is a solid which melts above 300°C. The study does not need to conducted because the given test chemical is a solid substance which melts above 300°C i.e greater than 360°C. hence present study is considered to be waiver.
From other reliable sources & authoritative databases boiling point of the test substance is determine to be 426.03°C & greater than 400°C.
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 found to be 0.5561 g/cm³ and 0.8002 g/cm³ at 26°C and 974.4 hPa.
From reliable sources density of test chemical is determine to be 1.89 g/cm3 at temperature 25 Deg C.
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 53 micron.
Vapour pressure:
The study does not need to conducted because the melting point of given chemical Disodium succinate (CAS No. 150-90 -3) is above 300°C i.e greater than 360°C. hence present study is considered to be waiver.
