Endpoint summary
Administrative data
Description of key information
Appearance:
On the basis of physical observation and using the sense of smell, Cyperus scariosus, ext. was observed to be a reddish to brown oily liquid having woody earthy odor.
Melting point:
Freezing point of chemical Cyperus scariosus, ext. was determine to be less than -9.3 Deg C.
Boiling Point:
The boiling point of Cyperus scariosus, ext. is in the range between 173.2 to 185.9 °C3.
Density:
The density of Cyperus scariosus, ext. is in the range between 0.9480 to 0.9870 g/cm3 at 25°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 observation and using the sense of smell, Cyperus scariosus, ext. was observed to be a reddish to brown oily liquid having woody earthy odor.
Vapour pressure:
The estimated vapour pressure of Cyperus scariosus, ext. at 25 deg C is in the range between 6.34 to 78.6 Pa.
Partition coefficient:
Based on the available data from modeling database EPI suite using the KOWWIN V1.68 programme, the estimated logPOW of the chemical Cyperus scariosus, ext. was estimated to be 5.32. On the basis of this estimated value, substance Cyperus scariosus, ext.can be considered to be hydrophobic in nature.
Water solubility:
The water solubility determination of Cyperus scariosus, ext. was done as per the shake flask method. The solubility of Cyperus scariosus, ext. determine to be less than 0.01 mg/L at 30 Deg C. Thus the chemical Cyperus scariosus, ext. is considered to be insoluble in water.
Surface tension:
The study does not need to be conducted because water solubility is below 1 mg/L at 20°C.
Flash point:
The flash point of Cyperus scariosus, ext. is dertermine to be greater than 110°C.
Auto flammability:
Cyperus scariosus, ext. did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Cyperus scariosus, ext. is not auto-flammable.
Flammability:
Cyperus scariosus, ext. 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 Cyperus scariosus, ext. is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Cyperus scariosus, ext. was considered non-flammable.
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 substance is a liquid.
