EC number: 939-516-4
CAS number: -
The physico-chemical properties of this UVCB substance have been
measured according to accepted methods, and data from the component
substance (glycerol) are used to support information requirements for
vapor pressure and octanol-water partition where measurements for the
UVCB mixture are problematic.
This substance occurs as a viscous, dark brown liquid at ambient
temperature (25 °C) and remains in liquid state at temperatures as low
as -90 °C. At standard atmospheric pressure, the substance boils at a
temperature of 250.17 °C. As the vapor pressure is dominated by the
presence of 4.98% water in the representative sample, boiling point of a
water-free substance is likely to be much higher. The vapor pressure of
a water-free sample is expected to be less than or equal to that of
glycerine (the primary component), which is 0.0223 Pa at 25 °C. The bulk
liquid substance has a density of 1.13 g/cm3 at 20 °C, and thus would
tend to sink in water before becoming fully dissolved. The water
solubility was measured to be > 1,000 g/L, and as such, the substance is
described as being miscible with water in all proportions. The surface
tension of an 0.1% wt. aqueous solution (68.7 mN/m at 20 °C is only
slightly less than that of pure water, and thus not indicative of
surface-active properties. The substance exhibits a flash point of 136
°C, but is regarded as not flammable upon contact with water, and not
explosive or oxidizing upon contact with water or other organic
materials. The major components of this UVCB substance do not possess
functional groups or atoms which may be ionized in aqueous solutions at
physiologically- or environmentally-relevant pH. The dynamic viscosity
of the substance is measured to be 5,651 mPa*sec at 20 °C. This
combination of high surface tension and high viscosity indicates the
substance to be of low concern for aspiration hazard.
