The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Disperse Blue 077 is a black powder, solid at 20 °C. No melting was observed until 230 °C. The boiling point could not be determined as the substance started to undergo thermic decomposition at about 230 °C. The density was determined to be 1.4962 g/cm³. The particle size distribution was determined as follows: L10: 2.527 μm; L50: 9.766 μm; L90: 35.174 μm. The substance decomposes even before melting occurs at 230 °C. Hence, the vapour pressure determination is considered as scientifically not necessary. The n-octanol/water partition coefficent of the test item at 20 °C, from the individual solubility in water and n-octanol, was determined to be (log Pow) >6.9. The water solubility of the test substance at a temperature of 20 °C was determined to be <0.85 μg/L (without correction for the purity). The surface tension was determined to be 75.954 mN/m at room temperature ca 20 °C. The variation of specification factor was 0.0 mN/m. FAT 40278/D is a solid substance and decomposes starting at 230 °C, hence, the flash point determination is considered as technically not feasible. No auto-ignition was observed until 550 °C. The substance should be considered as not highly flammable. The substance is considered to be non-explosive and not oxidising.
