No
Clinical signs:
Yes, signs of dermal irritation were observed.
Body weight:
No significant changes
Gross pathology:
No abnormalities were noted at necropsy.
Interpretation of results:
GHS criteria not met
Conclusions:
In the acute dermal toxicity study the discriminating dose was determined to be > 5000 mg/kg bw.
Executive summary:

In the non- GLP compliant but guideline similar acute dermal toxicity study New Zealand White rabbits were used. A dose of 5000 mg/kg bw was administrated 24 hours to the clipped abraded abdominal skin of ten rabbits.

Following exposure the binders were removed and observations made for mortality and toxic effects for a period of seven days.

No animals died during the course of the study. There was no evidence of toxicity from percutaneous absorption of the test substance. Signs of dermal irritation (erythema and edema) were observed until day 7.

No abnormalities were noted at necropsy.

All animals were essentially normal by the termination of the study. Therefore, the LD50 was determined to be > 5000 mg/kg bw.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed
Dose descriptor:
discriminating dose
Value:
5 000 mg/kg bw
Quality of whole database:
The study is not GLP compliant but equivalent to OECD guideline.

Acute oral toxicity

In the non-GLP compliant but guideline similar acute oral toxicity test with rats the following doses were tested 3200, 4000, 5000, 6250 mg/kg bw. 10 Wistar rats were used per dose.

The animals were observed for 14 days and necropsy of survivors was performed. The rats experienced lethargy and slow respiration. The LD50 of the test substance was determined to be 5700 mg/kg bw.

 

 

Acute dermal toxicity

In the non GLP compliant but guideline similar acute dermal toxicity study New Zealand White rabbits were used. A dose of 5000 mg/kg bw was administrated 24 hours to the clipped abraded abdominal skin of ten rabbits.

Following exposure the binders were removed and observations made for mortality and toxic effects for a period of seven days.

No animals died during the course of the study. There was no evidence of toxicity from percutaneous absorption of the test substance. Signs of dermal irritation (erythema and edema) were observed until day 7.

No abnormalities were noted at necropsy.

All animals were essentially normal by the termination of the study. Therefore, the LD50 was determined to be greater than 5000 mg/kg bw.


Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008 (oral)

Based on the results of the acute oral toxicity LD 50 = 5700 mg/kg bw the substance is not considered to be classified for acute oral toxicity under Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EU) No 2017/776.

 

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008 (dermal)

Based on the results of the acute dermal toxicity LD50 > 5000 mg/kg bw the substance is not considered to be classified for acute dermal toxicity under Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EU) No 2017/776.
