The density of test substance styrenated phenol (CAS no. 61788-44-1) was determined following OECD guideline OECD 109 according to pycnometer method. The density of the test substance was determine to be 1.078 gm/cm3 at 20 °C and 971.1 hPa.

From other experimental report and reliable sources the density of styrenated phenol was observed to be 1.067 g/cm3 at 37°C and 1.08 g/cm3 at 20°C respectively.

 

Particle size distribution (Granulometry)

Granulometry (particle size distribution) is a property that is relevant only to solids. Since Phenol, styrenated is a liquid substance this testing was scientifically not possible and hence this end point was considered for waiver.

 

Vapour pressure

The vapour pressure of phenol styrenated was observed to be very negligible ie less than 0.1Pa @20degree C.

 

Partition coefficient

KOWWIN V1.68 was used to estimate the octanol water partition coefficient of the test chemical Phenol, styrenated.

The estimated logPOW of the test chemical was 2.4148 dimensionless.Based on the estimated value, the test substance Phenol, styrenated can be considered hydrophillic in nature

 

Water solubility

The water solubility determination of test substance Styrenated phenol (CAS No. 61788-44-1) was done as per the spectrophotometric method. The solubility of Styrenated phenol in water was determine to be 1.95 mg/l at 220C.

 

Solubility in organic solvents / fat solubility

The solubility determination of test substance styrenated phenol (CAS No. 61788-44-1) in various organic solvents was done with acetone, acetonitrile, methanol, ethanol, toluene and Dimethylformamide (DMF). Thus, the solubility value of the test substance in acetonitrile, methanol, toluene and DMF was determine to be greater than 1000 g/l whereas the solubility value in acetone and ethanol was determine to be in the range of 200 – 1000g/l and 100-200 g/l, respectively at 32 °C.

 

Surface tension

Flash point

The flash point of styrenated phenol (CAS No. 61788-44-1) is 129°C at 965.7 hPa..

 

Auto flammability

Phenol, styrenated did not catch fire on being exposed to air at room temperature of 37 degC and atmospheric pressure of 760 hPa. This indicates that Phenol, styrenated is not auto-flammable.

 

Flammability

From the experimental values of flammability, Phenol, styrenated ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it. Thus it can be concluded that Phenol, styrenated is flammable only at high temperature of about 950 degC. However since such high temperatures are not determine under normal circumstances of transportation and use, Phenol, styrenated was considered non-flammable for chemical safety assessment.

 

Explosiveness

According to theoretical considerations based on chemical structure, Phenol, styrenated does not possess explosive properties. The reason for this is there are no chemical groups associated with explosive properties in Phenol, styrenated. Thus, as per column 2 of Annex VII this end point was considered for waiver.

 

Oxidising properties

Phenol, styrenated was determine to be non-oxidising.

Stability in organic solvents and identity of relevant degradation products

Phenol, styrenated was determine to be unstable in organic solvent dichloro methane and degradation product O - (Methyl Benzyl) Phenol was formed after 24 hours as evident from the GC-MS chromatogram obtained at 0 hours and that obtained after 24 hours.

 

pH

The pH determination of test substance styrenated phenol (CAS No. 61788-44-1) was done as per the test guideline OECD 122. The method followed was according topH meter. The pH was determine to be 6.85 at 300C.

 

Dissociation constant

The experimental pKa value for Phenol, styrenated was determine to be 0.000000369 at 37 degC indicating that it has dissociation properties. This value when converted at 20 deg C is equivalent to 0.000000199.

 

Viscosity

The viscosity determination of test substance styrenated phenol (CAS No. 61788-44-1) was done as per the test guideline OECD 114 using Redwood Viscometer No. 1.Kinematic viscosity (experimental) of test substance at 500C and 700C is481.403 mm2/sec and 163.26mm2/s respectively. Dynamic viscosity (calculated) of test substance at 500C and 700C is 515.1mPa.S and 174.6mPa.S, respectively.

From other experimental report, the dynamic viscosity of Phenol, styrenated was determine to be 987.36 mPa s at 28 degC.
