5000 mg/kg bw
No. of animals per sex per dose:
Control animals:
Details on study design:
The rats were observed twice daily for 14 days for mortality and toxicity. Body weights were recorded pretest, weekly and at death. All rats were examined for gross pathology.
Dose descriptor:
Effect level:
> 5 000 mg/kg bw
Based on:
test mat.
Remarks on result:
other: no mortality observed
Clinical signs:
other: Anogenital area stained brown (two females during two days) Chrornodacryorrhea (each one male and one female during one day) Dyspnea (one male during two days) Ptosis (one female during one day) Chromorhinorrhea (one male during one day)
Gross pathology:
One animal had parts of the intestine with a yellow coloration.
Interpretation of results:
GHS criteria not met
No mortality was observed at a single dose of 5000 mg/kg bw.
Endpoint conclusion
Endpoint conclusion:
no adverse effect observed
Dose descriptor:
discriminating dose
5 000 mg/kg bw

Acute toxicity: via inhalation route

Endpoint conclusion
Endpoint conclusion:
no study available

Acute toxicity: via dermal route

Link to relevant study records
acute toxicity: dermal
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance does not meet the criteria for classification as acute toxicity or STOT SE by the oral route and no systemic effects have been observed in in vivo studies with dermal exposure (e.g. skin irritation, skin sensitisation)
Endpoint conclusion
Endpoint conclusion:
no adverse effect observed

Additional information

The substance was tested in male and female Wistar rats for its acute oral toxicity at a limit dose of 5000 mg/kg bw. The study design is comparable to that of OECD testing guidelines for acute oral toxicity (ie 14 days observation period, recording of body weights, clinical signs and gross necropsy findings). Rats showed transient clinical signs. All animals survived the observation period.

Justification for classification or non-classification

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

The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance is not considered to be classified for acute oral or dermal or inhalation toxicity under Regulation (EC) No. 1272/2008.
