Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

Under the test conditions of this study, the acute oral median lethal dose to rats of Hydrochlor ultrafine was found to be greater than 2000 mg/kg bw.Based on these results, the test substance is not classified according to the Regulation (EC) N° 1272-2008 (CLP) and the GHS.

Executive summary:

In an acute oral toxicity study performed according to OECD Guideline 401 and in compliance with GLP, groups (5/sex/dose) of Sprague-Dawley rats were given Hydrochlor ultrafine at 2000 mg/kg bw. Animals were then observed for mortality, clinical signs for 14 days and were all sacrificed for macroscopic examination.

No mortality occurred. No significant clinical signs were observed. At necropsy, congestion was observed in the lungs of two rats, no abnormalities were observed in any of the remaining animals.

The acute oral LD50 for was found to be greater than 2000 mg/kg bw. Based on these results, the test substance was not classified according to the Regulation (EC) N° 1272-2008 (CLP) and the GHS.
