Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the dermal LD50 for the registered substance is higher than 2000 mg/kg bw in rats therefore it is not classified according to the Annex I of the Regulation EC No. 1272/2008 (CLP) and to the GHS.
- Executive summary:
In an acute dermal toxicity study (limit test) performed according to the OECD test guideline No. 402 and in compliance with GLP, five male and five female rats were treated with the substance at 2000 mg/kg by dermal application. The test item was diluted in vehicle (purified water) at a concentration of 0.5g/mL and administered at a volume dosage of 4mL/kg. The test site was covered with a semi-occlusive dressing for 24 hours. Animals were observed for mortality, clinical signs, local signs and body weights for 14 days and at the end of the study the surviving animals were sacrificed for macroscopic examination.
No clinical signs were observed throught the duration of the study. A moderate erythema was noted in all animals on test day 2 and persisted as slight up to test days 9 or 10. Slight to moderate scaling was observed in all animals from test days 3 or 6 to up to test days 10 or 15. Slight crusts were noted in two males on test days 6 to 10. Slight oedema was noted in all females on test days 3 to 5. No abnormalities were detected at necropsy.
Bodyweights were within the range commonly recorded for this strain and age. No abnormalities were noted at necropsy.
Dermal LD50 Combined > 2000 mg / kg bw
Under the test conditions, the dermal LD50 for the registered substance is higher than 2000 mg/kg bw in rats therefore it is not classified according to the Annex I of the Regulation EC No. 1272/2008 (CLP) and to the GHS.
