Description of key information
Appearance
On the basis of available data from study report,the appearance of test chemical was observed to be clear colourless liquid.
Melting point
Based on the available data from study report, the freezing point of test chemical was determined. The method was used crushed ice and salt at respective atmospheric pressure using Micro LAB Interface FS–524 data generation system and thermistor as temperature detection system. The test was conducted in replicates and mean freezing point was determined to be -5.37°C at 97830 Pa.
Boiling Point
Based on the available data from study report,the boiling point of test chemical was determined. The study was performed in accordance with the OECD Guideline 103 (Boiling Point). The method followed was according to Siwoloboff. The test was conducted in replicates and mean boiling point was determined to be 242°C at 96940 Pa.
Density
On the basis of available data from study report, the density of test chemical was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer. The mean density of test chemical was determined to be 0.9059 g/cm³ at 20.2°C and 973.1 hPa
Particle size distribution
The study does not need to be conducted because the test chemicalismarketed or used in a non-solid or granular form.
Vapour pressure
On the basis of available data from modelling database,the estimated vapour pressure of test chemical at 25 deg C was 0.00236 Pa.
Partition coefficient
Based on the available data from study report,the partition Coefficient n-octanol/water of test chemical was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 117 for testing of Chemicals. A test chemical solution was prepared by accurately measuring 4 micro liter of test chemical and diluted with methanol up to 10 ml. Thus, the test solution concentration was 367.2 mg/l. The pH of test substance was 7.6. The reference substances were chosen according to estimated Pow range of the test substance and generalized calibration graph was prepared. The reference substances were 4 -Acetylpyridine, Acetophenone, Benzophenone, 4-Methoxyphenol, Phenol, Benzene, Biphenyl, Methyl benzoate, Benzyl Benzoate, 1,4-Dichlorobenzene, 1,2,4-Trichlorobenzene, 2,6-Diphenylpyridine, Bromobenzene, 2,3-Dichloroaniline, Triphenylamine, Acetanilide, 2-Nitrophenol, Nitrobenzene, 2,6 -Dichlorobenzonitrile, Diphenylamine, Cinnamyl alcohol, Benzyl alcohol, Toluene, Ethylbenzene, n-Butylbenzene, Naphthalene, Diphenyl ether, Allyl phenyl ether, DDT having Pow value ranging from 0.5 to 6.5. The Log Pow value of the test chemical was determined to be 2.260 ± 0.001 at 25°C. On the basis of this value, test chemical is considered to be hydrophilic.
Water solubility
On the basis of available data from study report,the water solubility determination of test chemical was done as per the OECD guideline 105 (Water solubility) by spectrophotometric analytical method as per OECD 101.

Based on the available data from study report, the solubility of test chemical in methanol and petroleum ether at 24°C was determined to be 2800 mg/l and 8000 mg/L, respectively indicating that the test chemical is soluble in both methanol and petroleum ether.
Surface tension
On the basis of available data from handbook, the surface tension of test chemical was determined to be 36.3 mN/m at 23°C.
Flash point
Based on the available data from study report,the flash point of test chemical was determined. The experiment was performed by closed cup method using Pensky Martin’s Flash Point Apparatus. The flashpoint of the test chemical was determined to be 112°C at 96980 Pa
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 the test chemical is not auto-flammable.
Flammability
Flash point of test substance was determined to be 112°C at 96980 Pa. On the basis of GHS classification crtieria, test chemical has flash point greater than 60°C hence the test chemical was considered to be 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 the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied.
Stability in organic solvents
On the basis of available data from study report, Test chemical was reported to be unstable in the solvent dichloro methane and the degradation products identified were dodecyl alcohol, n-cetyl alcohol and myristyl ethoxylate.
pH
Based on the available data from study report,the pH of test chemical was determined. The study was performed as per the test guideline OECD Guideline 122 (Determination of pH, Acidity and Alkalinity). The mean pH of the test dispersion was determined with the help of digital pH meter. The mean pH was determine to be 6.25 at 24.6°C.
Dissociation constant
Based on the available data from study report, the dissociation constant (pKa) of test chemical was determined to be 0.00000000000057, 0.00000000000058 and 0.0000000000006, respectively at 24°C, indicating that it has dissociation properties.
Viscosity
Based on the available data from study report, the viscosity determination of test chemical was done as per the test guideline OECD 114 using Redwood Viscometer No. 1. Kinematic viscosity (experimental) of test chemical at 20°C and 40°C was determined to be 102.1592 mm²/sec & 29.9611 mm²/s and Dynamic viscosity of the test chemical was calculated to be 92.5460 mPa.S & 27.1417 mPa.S at 20°C and 40°C, respectively.
