Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
Under the test conditions, the oral LD50 of the test substance is >2000 but <5000 mg/kg bw therefore it is not classified according to the Regulation (EC) N° 1272-2008 but classified as ‘Category 5, No symbol: Warning’ according to the GHS.
Executive summary:

In an acute oral toxicity study, single oral doses of 2000, 2500, 3000, 3500, 4000 and 5000 mg/kg bw of the test substance were given to groups of rats (no. not specified). Animals were then observed for mortality and clinical signs of toxicity for 14 days.

 

Mortalities at 2000, 2500, 3000, 3500, 4000 and 5000 mg/kg bw were 0, 0, 1, 0, 2, 0 on Day 1; 0, 1, 3, 5, 5, 8 on Day 2; and 0, 0, 0, 0, 0, 0 on Days 3-14, respectively. Clinical signs included salivation, increased respiration, ataxia, exophthalmos, loss of righting reflex and depression until death.

 

Rat Oral LD50 = 3370±405 mg/kg bw.

 

Under the test conditions, the oral LD50 of the test substance is >2000 but <5000 mg/kg bw therefore it is not classified according to the Regulation (EC) N° 1272-2008 but classified as ‘Category 5, No symbol: Warning’ according to the GHS.

Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
Under the test conditions, the dermal LD50 of the test substance is 2500 mg/kg bw < LD50 < 5000 mg/kg bw in rabbits therefore it is not classified according to the Regulation (EC) N° 1272-2008 and is classified Category 5 according to the GHS.
Executive summary:

In an acute dermal toxicity study, 5 rabbits/dose were administered a single dermal dose of the test substance at 5000 and 2500 mg/kg bw. Animals were then observed for mortality, clinical signs of toxicity and dermal reactions for 14 days.

3 deaths occured at 5000 mg/kg bw on the first day of the observation period. No mortality was observed throughout the observation period at 2500 mg/kg bw. No clinical signs of toxicity occurred during the observation period. Dermal reactions noted were limited to one erythema at 24 h at 5000 mg/kg bw.

Under the test conditions, the dermal LD50 of the test substance is 2500 mg/kg bw < LD50 < 5000 mg/kg bw in rabbits therefore it is not classified according to the Regulation (EC) N° 1272-2008 and is classified Category 5 according to the GHS.
