- Weight at study initiation: Female 150 - 162 g; male 146 - 153 g
- Fasting period before study: Animals were fasted by withholding food over-night. Following the period of fasting the animals were weighed and the test substance was administered. Then the food was withhold for a further 3-4 hours.

- Remarks:
- Carboxymethylcellulose (1 % in aqua dest.)
- Details on oral exposure:
- VEHICLE
- Amount of vehicle: Carboxymethylcellulose; 1% in aqua bidest.
- Justification for choice of vehicle: The vehicle was chosen due to its non-toxic characteristics. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 3 males/3 females per dose
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The animals were weighed prior to first application and once a week thereafter.

Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred during the study.
- Clinical signs:
- other: No clinical signs of toxicity were observed throughout the observation period.
- Gross pathology:
- Necropsy revealed an acute injection of blood vessels in all animals in the abdominal region. This finding is due to euthanasia with an overdose of pentobarbital injected intraperitoneally.
- Other findings:
- None
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral median lethal dose (LD50) of the test material (EC: 433-100-1) in the Wistar rat (HsdBrl strain) was found to be greater than 2000 mg/kg bw.
- Executive summary:
The test substance (EC: 433-100-1) was tested for acute toxicity on oral administration in rats in a study according to EU Method B.1/OECD Guideline 423. A single dose of 2000 mg/kg bw was administered by oral gavage to 3 male and 3 female Wistar rats. The animals were observed for fourteen days for signs of toxicity. No signs of mortality or systemic toxicity were noted during the study. All animals showed an expected gain in body weight during the study. No abnormalities were noted at necropsy.
Therefore, the acute oral median lethal dose (LD50) of the test substance (EC: 433-100-1) was found to be greater than 2000 mg/kg bw.
