Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Additional information

Results from calculated classification (using mixture toxicity rules) are supported (WoE) by additional consideration from physico-chemical properties of the UVCB substance.

Chemistry of the substance (see IUCLID section 4.23 chemical and mineralogical characterization) confirms presence of species that trigger hazard. Substance is a solid, in pasty form when handled but powder when dried (see picture in IUCLID section 1.4 "sampling protocol") which particle size distribution (IUCLID section 4.5) for a worst case sample (ie material was dried) confirmed powder form. Water solubility (IUCLID section 4.8) furthermore demonstrated that substance is poorly soluble in water, with the exception of Cu, As, Ni, and S (ie sulphates)

Effects on skin irritation/corrosion: irritating

Effects on eye irritation: irritating

Effects on respiratory irritation: irritating
