Description of key information
Appearance:
On the basis of physical observations, it is concluded that Phenethyl propionate physically appear in colourless liquid form.
From other reliable sources and handbooks it is concluded that Phenethyl propionate physically appear as a colorless to yellowish liquid which is slightly oily having very sweet odor reminiscent of red rose with a fruity undertone.
Melting point:
The Freezing point determination of Phenethyl propionate (CAS No.122-70-3) was done using crushed ice and salt. No freezing was observed up -7.98°C. Hence, the freezing point was inferred to be less than -7.98 °C at 969.0 hPa.
Boiling Point:
The boiling point determination of Test item Phenethyl propionate (CAS No. 122-70-3 ) was done as per the test guideline OECD 103. The method followed was according to Siwoloboff. The mean boiling point was observed to be 239.8°C at 970.5 hPa.
Other reliable sources also concluded the boiling point of Phenethyl propionate is in the range of 231 to 245 Deg C.
Density:
The density of Test item Phenethyl propionate (CAS No. 122-70-3 ) was determined following OECD guideline 109 and according to the Indian standard method for determination of density of liquids [IS 4730:1994 (Reaffirmed 2010)]. The mean density of the test item was observed to be 1.0514 g/cm³at 20°C and 971.3 hPa.
Other reliable sources also cocnluded density of Phenethyl propionate is 1.02 g/cm3 at 25 Deg C and 1.4950 g/cm3 at 20 Deg C.
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 (On the basis of physical observations, it is concluded that Phenethyl propionate physically appear in colourless liquid form.)
Vapour pressure:
Vapour Pressure of chemical 2-phenylethyl propionate is determined to be 6.8527 Pa at 25 °C.
Partition coefficient
Based on the available data from publication and authoritative databases, the partition coefficient (log Pow) value of the substance 2-phenylethyl propanoate was estimated to be 3.06. On the basis of the estimated value, chemical 2-phenylethyl propanoate can be considered to be hydrophilic in nature.
Water solubility:
2-phenylethyl propionate moderately soluble in water as its water solubility determined to be 136 mg/L at 25 Deg C.
Surface tension:
Based on the data from ACD labs, surface tension for 2-phenylethyl propanoate was predicted to be 0.0355 N/m.
Flash point:
The flash point determination of Test item Phenethyl propionate (CAS No. 122-70-3 )was done. The method is closed cup method using Pensky-Martens Flash Point Apparatus. The mean flash point of the test item was observed to be 110°C at 970.4 hPa.
Other reliable sources also concluded flash point of Phenethyl propionate is greater than 93.33 Deg C.
Auto flammability:
2-phenylethyl propanoate did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2-phenylethyl propanoate is not auto-flammable.
Flammability:
2-phenylethyl propanoate 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 2-phenylethyl propanoate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2-phenylethyl propanoate 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
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.
pH:
The pH determination of test item Phenethyl propionate (CAS No 122-70-3) was done following OECD guideline 122. pH of 1% w/v emulsion was measured with the help of pH meter and it was observed to be 4.45at 27.5 °C.
Viscosity:
The viscosity determination of Test item Phenethyl propionate (CAS No. 122-70-3 )was done as per the test guideline OECD 114 using Redwood Viscometer No. 1. Kinematic viscosity (experimental) of Test item at 20°C and 40°C is 23.7120 mm²/sec and 17.2392 mm²/s, respectively. Dynamic viscosity (calculated) of Test item at 20°C and 40°C is 24.9307 mPa.S and 18.1252 mPa.S, respectively.
