Description of key information
Appearance
On the basis of physical observation, the appearance of test chemical was observed to be a colourless liquid.
Freezing point
On the basis of 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 < -7.5°C at 97150 Pa.
Boiling Point
Based on the 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 108°C at 96940 Pa.
Density
On the basis of 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 0.9405 g/cm³ at 20°C and 971.4 hPa.
Particle size distribution
The study does not need to be conducted because the substance is marketed or used in a non-solid or granular form.
Vapour pressure
Modified Grain method (Mean of Antoine and Modified Grain methods) was used to estimate the vapour pressure of the test chemical using MPBPVP v1.43 of EPI Suite. The estimated vapour pressure of the test chemical at 25°C was 3.7E-14 mmHg (4.93E-12 Pa).
Partition coefficient
Determination of the partition coefficient (logKow) value of test chemical. The study was performed using the Shake-flask method. The partition coefficient (logKow) value of test chemical was determined to be -0.224 (Kow = 0.597) at 37°C and pH of 5.45. On the basis of this value, test chemical was considered to be hydrophilic in nature.
Water solubility
On the basis of data from study report, the water solubility determination of test chemical was done as per the OECD guideline 105 (Water solubility) and OECD 101 by using spectrophotometric analytical method. The solubility of test chemical in water was determined to be 117630 mg/L at 25 ±2°C. On the basis of this value, test chemical was considered to be very soluble in water.
Surface tension
On the basis of available data from study report, surface tension of test chemical was determined. The study was performed in accordance with the ISO 9101:1987 Surface active agents: Determination of interfacial tension -Drop volume method. The mean surface tension of test chemical was determined to be 42.92 dynes/cm at 20º C and 970.4 hPa.
Flash point
Based on the data from study report, the flash point of test chemical was determined. The study was performed following the closed cup method using Pensky Martin’s Flash Point Apparatus. The flash point of the test chemical was determined to be 63.6°C at 96950 Pa. Thus, on the basis of criteria mentioned in CLP regulation, the chemical has flash point > 60°C hence the substance was considered to be not flammable.
Auto flammability
Test chemical did not catch fire on being exposed to air at room temperature of 28°C and at pressure of 975 hPa. This indicates that the test chemical is not auto-flammable.
Flammability
Flash point of test substance was determined to be 63.6°C at 96950 Pa. On the basis of GHS classification criteria, test chemical has flash point > 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
Test chemical was found to be oxidising since 58.73 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of test chemical. However, this oxidising property is very mild and does not classify the chemical as an oxidising.
Stability in organic solvents and identity of relevant degradation products
Test chemical was found to be stable in organic solvent dichloro methane and no degradation products were formed after 24 hours as evident from the GC-MS chromatogram obtained at 0 hours and that obtained after 24 hours.
pH
On the basis of data from study report, the pH of test chemical was determined.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 determined to be 10 at 22°C. Thus, test chemical was considered to be basic in nature.
Dissociation constant
The experimental pKa value of the test chemical was determined to be 0.00000000028, 0.00000000028 and 0.00000000029 at 37°C, indicating that the chemical has no dissociation properties.
Viscosity
Based on the data from study report, the viscosity determination of test chemical was done as per the test guideline OECD 114 using Redwood Viscometer. Kinematic viscosity (experimental) of test chemical at 20°C and 40°C was determined to be 17.3184 mm²/sec & 10.9032 mm²/s and Dynamic viscosity of the test chemical was calculated to be 16.2879 mPa.S & 10.2544 mPa.S at 20°C and 40°C, respectively.
