EC number: 701-459-6
CAS number: -
The substance is considered as insoluble and inert since water solubility is < 0.1 mg/L (see IUCLID chapter 4.8, water solubility) and a negligible bioavailability of the metal ions was proven for the inhalation and oral route (see IUCLID chapter 7.1.1 basic toxicokinetics).
For risk assessment the German AGW value (maximum occupational limit; formerly MAK) for inert dusts can be taken into account. In 1997, the German MAK commission stated the AGW of the respirable fraction of inert dusts to be 4 mg/m3 in order to prevent unspecific local effects in the respiratory tract (predominantly chronic bronchitis).
The AGW of the alveolar fraction was stated to be 1.5 mg/m3.
The pure substance is not handeled by the general population and has no
consumer use. The concentration in articles is 5% maximum.
