Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Acute Toxicity: inhalation

- Endpoint:
- acute toxicity: inhalation
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- other:
- Justification for type of information:
- It was considered inappropriate to formulate the test item using a suitable vehicle as this would not be representative of the hazard that the test item poses in everyday use. Therefore, attempts were made to generate an atmosphere of the test item as supplied.
Three generation trials were carried out in an attempt to generate a dust atmosphere with mass median aerodynamic diameters (MMAD) ranging from 1 to 4 µm (details of these trials are recorded in materials and methods). At approximately 5 mg/L the minimum MMAD generated was 8.91 µm with the percentage of particles less than 4 µm = 33.1%.
In view of the physical nature of the test item and its apparent low volatility it is considered unlikely to represent a significant hazard by the inhalation route.

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
