Description of key information

The concentration of 2.19 mg/m³ in the air represents the  technically achievable limit. Since at this concentration only overload effects to the tissue of the respiratory tract, but no toxic effects were observed, this value cannot considered to be the LC50 for the classification of the substance. The substance fulfils the criteria of inert dust and can be classified as “not dangerous” with respect to acute toxicity. This is underpinned by results of the studies described in chapter 5.6 and 5.10.
The substance has a low acute toxicity, which is not relevant for the practical use. The data are not leading to a classification according to DPD/DSD or CLP-system
