Additional information

Studies conducted in accordance with EU guidelines are available for: appearance, melting point, boiling point, relative density, particle size distribution, dustiness and water solubility.

Waivers are proposed for boiling point, vapour pressure, partition coefficient, surface tension, flash point, auto flammability, flammability for solids, pyrophoric properties, flammability in contact with water, explosiveness, oxidising properties, stability in organic solvents, dissociation constant and viscosity.
