Description of key information
Appearance/physical state/colour:
The substance is a white to off-white, odourless powder at room temperature.
(Source: internal company data)
Melting point:
Benzethonium chloride underwent decomposition during melting over the temperature range 162 to 166°C.
(Source: GLP-report)
Boiling point:
Benzethonium chloride does not possess a boiling temperature but underwent decomposition during melting over the temperature range 162 to 166°C.
(Source: GLP-report)
Density:
The density was found to be 1.10 g/cm3 at 20°C.
(Source: GLP-report)
Particle size distribution:
The results indicate that 2.7% by mass of the test item is smaller than 10 um..
(Source: GLP-report)
Vapor pressure:
The vapour pressure of Benzethonium chloride is 2.74 x 10-8 Pa at 25°C
(Source: GLP-report)
Partition coefficient n-octanol/water:
The log Pow was estimated to be 1.08 at a temperature of 20°C.
(Source. GLP-report)
Water solubility:
The solubility of Benzethonium chloride was determined to be > 534 g/l in pH 5 buffer, > 543 g/l in water and > 530 g/l in pH 9 buffer at 20°C.
(Source: GLP-report)
Surface tension of an aqueous solution:
The surface tension of an aqueous solution of the test item (1g/l) was determined to be: 33.4 mN/m at 20 °C. Benzethonium chloride needs to be regarded as surface active material.
(Source: GLP-report)
Flash point:
Not applicable to solid substances.
(Source: Expert assessment)
Auto flammability:
The relative self-ignition temperature of the test item is > 400°C at atmospheric pressure and therefore considered to be not autoflammable.
(Source: GLP-report)
Flammability:
The substance is not flammable. Based on the chemical structure, the test item does neither react with water nor evolve any flammable gases in contact with (humid) air.
(Source: GLP-report and expert assessment)
Explosiveness:
Based on chemical structure and information on handling and use the substance was considered non-explosive. Experimental determination was waived.
(Source: Expert assessment)
Oxidizing properties:
From the assessment of the chemical structure it was established that the test substance would not have oxidizing properties.
