Additional information
Studies conducted in accordance with EU guidelines are available for: appearance, decomposition temperature, relative density, particle size distribution, dustiness and transformation / dissolution.
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
