Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated informationCriteria used for interpretation of results: EU
Conclusions:
Calculation based on long-term oral key study of aluminium potassium bis sulphate from Oneda et al. resulted in an NOAEL inhalative -20 month mouse of NOAEL inhalative= 13.05 mg Aluminium potassium bis sulphate/m³ air.The resulting LC50 inhalative should be > 5 mg/L air (Limit GHS).Therefore the substance is not classified according to EU regulation 1272/2008 and EU regulation286/2011 (2. ATP).
Executive summary:

Calculation based on long-term oral key study of aluminium potassium bis sulphate from Oneda et al.

resulted in an NOAEL inhalative -20 month mouse of NOAEL inhalative = 13.05 mg Aluminium potassium bis sulphate/m³ air.

The resulting LC50 inhalative should be > 5 mg/L air (Limit GHS).

Therefore the substance is not classified according to EU regulation 1272/2008 and EU regulation

286/2011 (2. ATP).
