Description of key information
Appearance:
Based on available data from authoritative database, the chemical sodium benzenesulfinate was observed to be white coloured powder in appearance
Melting point:
Based on available data from various reliable sources such as authoritative database and handbook, the melting point of chemical sodium benzenesulfinate was determined to be >300 degree C.
Boiling point:
The study does not need to be conducted because the substance is a solid which melts above 300°C.
Density:
Based on prediction done using ACD/I-Lab 2.0,the density of chemical sodium benzenesulfinate was estimated to be1.45 ± 0.1 g/cm3
Particle Size Distribution:
The particle size distribution of test item sodium benzenesulfinate was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 150 micron to 25 micron.
Vapor Pressure:
The study does not need to be conducted since the melting point is above 300 deg C .The melting point of sodium benzenesulfinate was determined to be >300 degree C.
Hence, this endpoint was considered for waiver.
Partition Coefficient:
The experimental octanol water partition coefficient (logPow) for sodium benzenesulfinate was -3.54
The estimated octanol water partition coefficient (logPow) of sodium benzenesulfinate was -3.04
The experimental and estimated values suggest that sodium benzenesulfinate is hydrophillic in nature
Water Solubility:
Data from various authoritative databases suggests that the estimated solubility of sodium benzenesulphinate in water at 25 deg C was1000000 mg/L.This value indicates that sodium benzenesulphinate is highly soluble in water.
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
Surface tension:
The study does not need to be conducted because surface activity is not a desired property of the material.
Flash point:
The flash point determination of test substance sodium benzenesulfinate 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 115 °C at 980.9 hPa. Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the substance was considered to be non-flammable.
Autoflammability:
Sodium benzenesulfinate did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that sodium benzenesulfinate is not auto-flammable.
Flammability:
Sodium benzenesulfinate 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 sodium benzenesulfinate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus sodium benzenesulfinate was considered non-flammable for chemical safety assessment.
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
Viscosity:
The study does not need to be conducted because the substance is a solid
