Description of key information

Additional information

- Acid Blue 185 is a black powder, solid at 20 °C with neutral smell.

- The melting point of Acid Blue 185 could not be determined as no melting occurred until 350 °C.

- The boiling point of the substance could not be determined as no boiling observed until 350 °C.

- The relative density of Acid Blue 185 was determined to be 1.5241.

- The median particle size of Acid Blue 185 was determined to be 25.999 μm.

- A study for vapour pressure determination was not performed since no melting point has been determined up to 350 °C.

- The partition coefficient n-octanol/water (log Pow) of Acid Blue 185 at 20 °C, determined from the individual solubility in water and n-octanol, was < -5.9 (Pow < 0.0000012).

- The water solubility of Acid Blue 185 at a temperature of 20 °C was determined to be 485.2 g/l.

- Acid Blue 185 was determined to have a surface tension of 72.837 mN/m.

- The flash point was not determined, as the substance is a powder / solid at room temperature with a melting point >350 °C.

- The auto-ignition temperature of Acid Blue 185 could not be determined as no auto-ignition occurred until 550 °C.

- The substance was considered to be not highly flammable as it did not show ignition during the preliminary screening test.

- The substance was judged not to have oxidising or explosive properties.
