Description of key information
Appearance:
On the basis of physical observation and using the sense of smell, Benzyl 4-hydroxybenzoate was observed to be a creamy white crystalline odourless powder.
Melting point:
The melting point determination of Test item Benzyl 4-hydroxybenzoate (CAS No. 94-18-8 ) was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The Mean melting temperature range was determine to be 108.8 -111.6°C at 969.7 hPa.
Boiling Point:
The boiling point determination of Benzyl 4-hydroxybenzoate (CAS No. 94-18-8) was done following OECD Guideline 103 and according to the method of Siwoloboff. No string of bubbles were observed up to 300 °C, after melting above 108 °C. Inferring boiling point to be greater than 300°C at 970.2 hPa.
Density:
The density of test item Benzyl 4-hydroxybenzoate (CAS No. 94-18-8)was determined following OECD Guideline 109 and according to the Adapted from ASTM D854-02 using glass pyknometer .The mean density of test item was determine to be 1.5307 g/cm³at 20 °C and 969.4 hPa.
Particle size distribution:
The particle size distribution of test item Benzyl 4-hydroxybenzoate (CAS No. 94-18-8 ) was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determine to be in the range of 150 micron to 25micron.
Vapour pressure:
The estimated vapor pressure of benzyl 4-hydroxybenzoate at 25°C is 4.4929E-4 Pa.
Partition coefficient:
Water solubility:
The water solubility determination of test item Benzyl 4-hydroxybenzoate (CAS No. 94-18-8) was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of (Benzyl 4-hydroxybenzoate of 94-18-8 ) in water was found to be 72.082 mg/L at 30°C. Thus Benzyl 4-hydroxybenzoate (CAS No. 94-18-8) is considered to be Slightly soluble in water.
Surface tension:
In accordance with column 2 of Annex VII of the REACH regulation, the study need only be conducted if surface activity is a desired property of the chemical. The chemical Benzyl 4-hydroxybenzoate is widely used as a preservative in cosmetics. For this use, surface activity is not an important property. Hence this study was considered for waiver.
Flash point:
The flash point determination of Test item Benzyl 4-hydroxybenzoate (CAS No. 94-18-8 )was done. The method is closed cup method using Pensky-Martens Flash Point Apparatus. The meanflash point of the test item was determine to be 169°C at 970.0 hPa.
Auto flammability:
Benzyl 4-hydroxybenzoate did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that Benzyl 4-hydroxybenzoate is not auto-flammable.
Flammability:
Benzyl 4-hydroxybenzoate 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 Benzyl 4-hydroxybenzoate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Benzyl 4-hydroxybenzoate was considered non-flammable.
Explosiveness:
In accordance with column 2 of Annex VII of the REACH regulation, the study does not need to be conducted since there are no chemical groups associated with explosive properties present in the molecule of Benzyl 4-hydroxybenzoate. Thus, this end point was considered for waiver and the chemical is considered to be "Non explosive".
Oxidizing properties:
In accordance with column 2 of Annex VII of the REACH regulation, the substance Benzyl 4-hydroxybenzoate is incapable of reacting exothermically with combustible materials on the basis of the chemical structure. It is an organic substance containing oxygen but no halogen atoms and these elements are not chemically bonded to nitrogen or oxygen. Thus, the chemcial is likely to be "Non-oxidising".
pH:
The pH determination of test item Benzyl 4-hydroxybenzoate (CAS No 94-18-8) was done following OECD guideline 122. pH of 1% w/v dispersion was measured with the help of pH meter and it was observed to be 6.98 at 30°C.
