Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Remarks:
- Correction was made for the purity of the test substance, which was set at 35% for calculations in consultation with the Study Monitor.
- Details on oral exposure:
- MAXIMUM DOSE VOLUME APPLIED: 4.19 mL/kg for 2000 mg/kg and 0.629 mL/kg for 300 mg/kg.
DOSAGE PREPARATION (if unusual):
The test substance was dosed undiluted as delivered by the sponsor. Dose levels were corrected for the purity of the test substance, which was set at 35% for calculations in consultation with the Study Monitor. Dose volumes were calculated as: Dose level (g/kg) / density (g/mL).
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: Not indicated - Doses:
- 2000 mg/kg and 300 mg/kg. Single dosage, on Day 1.
Dose levels were corrected for the purity of the test substance, which was set at 35% for calculations in consultation with the Study Monitor.
The toxicity of the test substance was assessed by stepwise treatment of groups of 3 females. The first group was treated at a dose level of 2000 mg/kg. The absence or presence of mortality of animals dosed at one step determined the next step, based on the test procedure defined in the guidelines. The onset, duration and severity of the signs of toxicity were taken into account for determination of the time interval between the dose groups. - No. of animals per sex per dose:
- 2000 mg/kg: 3 females
300 mg/kg: 2: 6 females (2 groups of 3 animals were treated in a stepwise fashion) - Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days (Day 1 - Day 15)
- Frequency of observations and weighing:Clinical signs at periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15 (see 'Any other information on materials and methods inc. tables). Body weights on Days 1 (pre-administration), 8 and 15 and at death.
- Necropsy of survivors performed: yes (see 'Any other information on materials and methods inc. tables)
- Other examinations performed: Mortality/viability was observed twice daily. The time of death was recorded as precisely as possible. - Statistics:
- No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50 value).

- Mortality:
- The incidence of mortality was as follows, presented in chronological order of treatment:
Dose level Mortality Date of treatment

300 mg/kg 0/3 01 April 2010
300 mg/kg 1/3 08 April 2010
The decedents were found dead within 24 hours post-treatment.
See attached document 'Results tables'. - Clinical signs:
- Clinical signs observed during the study period were as follows:
Dose level Clinical signs
2000 mg/kg Lethargy, hunched posture, piloerection and ptosis.
300 mg/kg Lethargy, hunched posture, uncoordinated movements, piloerection and/or ptosis.
The surviving animals had fully recovered from the symptoms between Days 4 and 6.
See attached document 'Results tables'. - Body weight:
- The body weight gain shown by the surviving animals over the study period was considered to be similar to that expected of normal untreated animals of the same age and strain.
See attached document 'Results tables'. - Gross pathology:
- Animals that were found dead at 2000 mg/kg and 300 mg/kg showed a combination of the following findings at macroscopic post mortem examination: beginning or advanced autolysis, black-brown discolouration of the glandular mucosa of the stomach, gray-white, black-brown or reddish foci on the glandular mucosa of the stomach, hardened glandular mucosa of the stomach, dark red foci on the forestomach, distention of the stomach with gas, greenish and dark red foci on lungs, hardened lungs, dark red discolouration of the pancreas, enlargement of the spleen, reddish discolouration of the wall of the duodenum, dark red or black-brown foci on the thymus, yellowish foci on the uterus and yellowish discolouration of uterine adipose tissue in the abdominal cavity.
No macroscopic abnormalities were observed for animals at 300 mg/kg that survived until termination.
See attached document 'Results tables'. - Other findings:
- Not appplicable.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on these results: LD 50 (rat, oral) > 2000 mg/kg bw based on test substance
- according to the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) of the United Nations (2007), 202029/A should not be classified for acute toxicity by the oral route.
- according to the Regulation (EC) No 1272/2008 on classification, labeling and packaging of substances and mixtures, 202029-A should not be classified. - Executive summary:
In the study report a calculation is used to determine the dose which disregarded the water contained in the material as a solvent and use doses assuming only 35 % active in the solution. Thus, very high doses were applied.
However, basic Aluminum chloride cannot be isolated from the aqueous solution without changing the chemical composition and properties. Thus, the water in this case is not a simple solvent, that could be disregarded, but an integral consituent of the test material stabilizing the substance. The water, therefore, must not be disregarded when determining the dose. The consequence is that the dose relevant for classification & labelling is not the amount of theoretically applied active material (as done by the authors of the study) but the amount of material as it was provided; i.e. about 3- fold higher and above the limits for classification. LD 50 (rat, oral) > 2000 mg/kg bw
When using this approach the material does not need to be classified and labelled for acute oral toxicity.
