Results
Due to its nature, it proved impossible to generate consistent, controllable and reliable atmospheres of the test material in its normal or ground state. It was, therefore, not possible to continue this study so as to expose animals to an atmosphere of the material suitable for an acute inhalation study.
Applicant's summary and conclusion
- Interpretation of results:
- other: not to be possible to generate a suitable test atmosphere from the test material
- Conclusions:
- The dust generation properties of Semi Dry Absorption (SDA) Product were shown to be low and mechanical systems designed to produce dust aerosols were unsuccessful in producing a dust atmosphere. It was, therefore, considered not to be possible to generate a suitable test atmosphere from the test material, for use in an inhalation study.
In view of the physical nature of the test material, its apparent low volatility and its apparent hygroscopic nature, it is considered unlikely to represent a significant hazard by the inhalation route.
