Clinical observations were made 1/2, 1, 2, and 4 hours after dosing and then daily for up to 14 days. Morbidity and mortality checks were made twice daily. Individual bodyweights were recorded on Day 0 (the day of dosing) and on Day 7 and 14 or at death.
- Necropsy of survivors performed: At the end of the observation period the surviving animals were killed by cervical dislocation. All animals were subjected to gross necropsy. This consisted of an external examination and opening of the abdominal and thoracic cavities. The appearance of any macroscopic abnormalities was recorded. No tissues were retained.
- Other examinations performed: clinical signs, body weight, necropsy and mortality. - Statistics:
- Not reported.
Results and discussion
- Preliminary study:
- In the absence of data regarding the toxicity of the test material, 300 mg/kg was chosen as the starting dose.
In the absence of toxicity at a dose level of 300 mg/kg, an additional animal was treated as follows,
One animal at 2000 mg/kg and 4 animals at 300 mg/kg.
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 300 - <= 2 000 mg/kg bw
- Mortality:

Applicant's summary and conclusion
- Interpretation of results:
- harmful
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute oral median lethal dose (LD50) of the test material in the female Sprague-Dawley CD strain rat was estimated to be in the range of 300 ‑ 2000 mg/kg bodyweight. The test substance is classified as R22 Harmful if swallowed under Council Directive 67/548/EEC and Category 4 H302: Harmful if swallowed under Regulation (EC) No 1272/2008.
- Executive summary:
Introduction. The study was performed to assess the acute oral toxicity of the test material in the Sprague‑Dawley CD strain rat. The method was designed to meet the requirements of the following:
§ OECD Guidelines for Testing of Chemicals No 420 “Acute Oral Toxicity - Fixed Dose Method” (2001)
§ Method B1 Acute Toxicity (Oral) of Commission Directive 2004/73/EC
Method. Following a sighting test at dose levels of 300 mg/kg and 2000 mg/kg, a further group of four fasted females was given a single oral dose of test material, as a solution/emulsion in distilled water, at a dose level of 300 mg/kg bodyweight. Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy.
Mortality. The animal treated at a dose level of 2000 mg/kg was killed in extremis two days after dosing.
Clinical Observations. There were no signs of systemic toxicity noted in animals treated at a dose level of 300 mg/kg. Hunched posture, lethargy, pilo-erection, decreased respiratory rate, laboured respiration, diarrhoea, diuresis, hypothermia, ataxia, pallor of the extremities, ptosis and dehydration were noted in the animal treated at a dose level of 2000 mg/kg.
Bodyweight. Surviving animals showed expected gains in bodyweight.
Necropsy. No abnormalities were noted at necropsy.
Conclusion. The acute oral median lethal dose (LD50) of the test material in the female Sprague‑Dawley CD strain rat was estimated to be in the range of 300 ‑ 2000 mg/kg bodyweight. The test substance is classified as R22 Harmful if swallowed under Council Directive 67/548/EEC and Category 4 H302: Harmful if swallowed under Regulation (EC) No 1272/2008.
