Description of key information

Additional information

Zinc bis(dibutyldithiocarbamate) is a white powder with a melting range between 100-112 °C at 101.325 kPa (Analytical laboratory in Termoli, 1998), a boiling temperature of 318°C (Currenta GmbH & Co. OHG, 2010a) and a relative density of 1.42 at 20°C (Analytical Laboratory in Termoli, 1998). Its vapour pressure is determined to be < 1E-04 Pa (Intertek, 2012). Its water solubility is considered to be below 1 mg/L, based on data on a structural analogue zinc bis(diethyldithiocarbamate) (Currenta GmbH & Co. OHG, 2010b). The substance is non-flammable, non-oxidizing and non-explosive.

Information on the Log Kow will be submitted later based on ECHA decision number CCH-D-2114375518-38-01.

In accordance with Column 2 of REACH Annexes VII-X and/or Sections 1 or 2 of REACH Annex XI and/or Chapter R.7A of REACH Guidance on information requirements and chemical safety assessment, conductance of the studies on surface tension, partition coefficient, auto flammability, stability in organic solvents, dissociation constant and viscosity are not warranted.

The following particle size distribution was determined (Currenta GmbH & Co. OHG, 2010c):

0.04% < 4 μm; 0.92% in the range of 4-10 μm; 99.05% in the range 10-100 μm (spherical volume).

0.44% < 4 μm; 1.07% in the range 4-10 μm; 98.89% in the range 10-100 μm (cubical volume).

The median diameter was 18.7 μm.
