Melting point/Freezing point:

Freezing point of test chemical was determined to be  -5.63 degree celcius.

Boiling point:

In an experiment,the boiling point determination of test item was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was determined to be 213.3°C at 972.4 hPa.

Density:

The density of test chemical was determined following OECD Guideline 109 and according to theIS 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 1.4162 g/cm³ at 20°C and 968.1 hPa.

Particle Size Distribution:

The study does not need to be conducted because the test chemical is marketed or used in a non- solid or granular form.

Test chemical was observed to be yellowish coloured liquid having strong floral odour.

Vapor Pressure:

The estimated vapor pressure of test chemical at 25 deg C was 16.4 Pa.

Partition Coefficient:

The partition Coefficient n-octanol/water of test chmeical was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 117 for testing of Chemicals. The reference substances were chosen according to estimated Pow range of the test substance and generalized calibration graph was prepared.

The reference substancesBenzene, Biphenyl, 4-Acetylpyridine, Toluene, Ethylbenzene, n-Butylbenzene, Naphthalene were chosen having log Pow

range from 0.5 to 4.6

The Log Pow value was determined to be3.391 ± 0.005dimensionless at 25°C.

This value indicates that the substance is hydrophilic in nature.

Water Solubility:

The solubility of test chemical in water was determine to be 56.624 mg/L at 25°C.

Thus the test chemical is considered to be slightly soluble.

Surface tension:

Based on the data from ACD labs, surface tension for test chemical was predicted to be 41.5 ± 3.0 dyne/cm.

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 79.6°C at 970.2 hPa.

Autoflammability:

Test chemical did not catch fire on being exposed to air at room temperature of 27°C at a 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 for chemical safety assessment.

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 oxidising properties and hence, the classification procedure does not need to be applied.

pH:

The pH determination of test chemical 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 determined to be 4.61 at 30.5 °C.

Viscosity:

Dynamic viscosity (calculated) of test chemical at 20 0C and 40 0C is 21.1614 mPa.S and 16.3010 mPa.S,  respectively.
