Description of key information
Appearance / physical state / colour
On the basis of physical observation, test chemical was observed to be clear pale yellow liquid.
Melting point/ Freezing point
Experimental study was performed according to OECD 102 wherein Freezing point of test chemical was found to be -2.54°C at 969 hPa
Boiling point
The boiling point determination of test chemical was done as per the test guideline OECD 103. The method followed was according to Siwoloboff. The boiling point of test chemical was determined to be 136°C at 968.9 hPa
Density
The mean density of test item was determined to be 0.90 g/cm³ at 20°C .
Particle size distribution (Granulometry)
The study does not need to be conducted because the substance is marketed or used in a non solid or granular form.
Vapour pressure
Based on the data from modelling database, 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 vapour pressure of test chemical at 25°C was estimated to be 0.00403 mmHg (0.537 Pa).
Partition coefficient
KOWWIN V1.68 was used to estimate the octanol water partition coefficient of the test chemical. The partition coefficient (logKow) value of the test chemical was estimated to be 1.1633 at 25°C.
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 determined to be 2199.6 mg/L at 25°C ±2°C.
Thus the test chemical is considered to be soluble in water.
Surface tension
Experimental study was performed adapting method fromISO 9101:1987 Surface active agents: Determination of interfacial tension -Drop volumemethod.
The surface tension of test substance was determined to be 41.07 mN/m at 20 ºC and 969.5 hPa .
Flash point
The flash point determination of test substance was done as per the test guideline OECD 103. The method is closed cup method using Pensky Martin’s Flash Point Apparatus. The flashpoint of the test substance was determined to be 91.3°C at 969 hPa
Autoflammability
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 91.3°C . 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
Oxidising 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 dispersion was determined with the help of digital pH meter. The mean pH was determine to be 11.38 at 22.4 °C , inferring its basic nature.
Additional information
Appearance / physical state / colour
On the basis of physical observation, test chemical was observed to be clear pale yellow liquid.
Melting point/ Freezing point
A study was performed to determine the Freezing point of test chemical at respective atmospheric pressure.
The study was conducted as per OECD 102 Adopted 27.07.95 using Micro LAB Interface FS–524 data
generation system and thermostat as temperature detection system.
The Mean Freezing Point was observed to be -2.54°C at 969.0 hPa.
Boiling point
Density
A study was performed to determine the density of test chemical in respective atmospheric pressure and temperature conditions.
The study was conducted in accordance with OECD guideline for the Testing of Chemicals no. 109; Density of Liquid and Solids, Adopted: 2 October 2012 and Method adapted from IS 4730:1994 (Reaffirmed 2003) Method for determination of Density of Liquids.
The mean density of test chemical was determined to be 0.90 g/cm3at 20 °C and970.4 hPa.s
Particle size distribution (Granulometry)
The study does not need to be conducted because the substance is marketed or used in a non solid or granular form.
Vapour pressure
Based on the data from modelling database, 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 vapour pressure of test chemical at 25°C was estimated to be 0.00403 mmHg (0.537 Pa).
Additional data from modelling database indicates the vapour pressure of test chemical as 0.00169 mmHg (0.2253 Pa) at 25°C..
Partition coefficient
KOWWIN V1.68 was used to estimate the octanol water partition coefficient of the test chemical. The partition coefficient (logKow) value of the test chemical was estimated to be 1.1633 at 25°C.
In a supporting data from modelling database, the partition coefficient value of test chemical was estimated to be 1.116 ± 0.408 at 25°C.
Thus, on the basis of available information, the partition coefficient value of the test chemical ranges from 1.11 to 1.16, respectively, indicating the test chemical as hydrophilic in nature.
Water solubility
The study was conducted to determine the solubility of test chemical in ultra-pure water, according to the OECD guideline 105 (Adopted by the Council on 27th July 1995) and OECD 101(Adopted: 12 May 1981). Test was conducted at 25±2 °C in two stages; preliminary testfor 24 h, followed by confirmatory test for 24 h, 48 h and 72 h in replicates. The final water solubility value was calculated based on average of the individual values obtained after 24 h, 48 h and 72 h. The difference between the average values in three vessels was not observed more than 15%. The water solubility value was observed to be2199.6 mg/L at 25±2°C
