Endpoint summary
Administrative data
Description of key information
In an OECD 423 study the LD50 oral (female rat) is greater than 2000 mg/kg body weight.
The acute inhalation toxicity study has been waived as exposure via this route is unlikely.
In an OECD 402 study the LD50 dermal (rat) was determined to be greater than 2000 mg/kg body weight.

All animals were examined for clinical signs at approximately 30 minutes, 1, 2, 3 and 5 hours after treatment on day 1 and once daily during test days 2-15. Mortality/viability was recorded at approximately 30 minutes, 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during days 2-15. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically.All animals survived until the end of the study period.
Hunched posture was noted in all animals at the 3-hour reading and persisted in three animals until the 5-hour reading.
The body weight of the animals was within the range commonly recorded for this strain and age.
No macroscopic findings were recorded at necropsy.The LD50 (female rat) is greater than 2000 mg/kg body weight.

Acute toxicity: via inhalation route
Link to relevant study records
- Endpoint:
- acute toxicity: inhalation
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size

No deaths occurred during the study.
Slight erythema was observed in all animals on test day 2 and persisted in three males and three females until test day 3, 4 or 7, respectively. Scaling was noted, in three females on test day 4 and persisted in two animals until test day 7, and in three males from test day 4 to 7 persisting in two animals until test day 10 and 11, respectively. Slight crusts were noted in one animal from test day 8 to 10.
