- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Animals were observed soon after dosing; then at frequent intervals for the remainder of Day 1. On
subsequent days the animals were observed at least twice per day. Clinical signs were recorded at each observation. Individual bodyweights of rats on Days 1 (day of dosing), 4, 8 and 15 and at death.
- Necropsy of survivors performed: yes
- Other examinations performed: other: only in stage III
On Days 2 and 7 samples of blood were withdrawn, under light ether anaesthesia, from the orbital sinus of all rats. The blood samples were placed in EDTA anti-coagulant tubes for subsequent; haernatological investigations. The following estimations were performed:
Total white cell count (WBC Total), Differential WBC counts - standard, microscopy of blood smear, stained with modified Wright's stain counting 100 cells, Neutrophils (N), Lymphocytes (L), Eosinophils (E), Basophils (B), Monocytes (M). - Statistics:
- The LD50 and its 95% confidence limits were estimated for both males and females separately, based on the method of Brownlee, Hodges and
Rosenblatt. For haematological data statistical analysis was carried out using the individual animal as the basic experimental unit. The following sequence of statistical tests was used for haematological parameters in which the relative frequency of the mode was less than 75% (i.e. the data did not consist predominant of one particular value):
(i) Bartlett's test was applied to test for heterogeneity of variance between treatments. Where significant (at the 1% level) heterogeneity was found, a log transformation was tried to see if the heterogeneity was removed.
(ii) If no satisfactory transformation was found the Kruskal-Wallis analysis of ranks was used.
(iii) Analyses of variance were followed by Student's 't' test for a-dose-related response. The Kruskal-Wallis analyses were followed by the non-parametric equivalent of the, ' t' test.
For those parameters in which the relative frequency of the mode is 75% or more, the number of animals in each group with values different
from the mode will be analysed using Fisher's exact test and Mantel's test. Fisher's test will be used to detect general differences between treatments, whereas Mantel's test will be used specifically for detecting dose-related trends in the numbers of such animals.

- Remarks on result:

- Mortality:
- Stage I:
All rats dosed at 2000 mg/kg were found dead within one or two days of treatment.
Stage II:
Death occurred amongst male rats at 800 mg/kg and above and amongst female rats at 500 mg/kg and above within one to four days of dosing.
Stage III:
Based on the results from stage I and II rats were dosed at the expected maximum sub-lethal dose.
The treatmnet started with 320 mg/kg bw but one female rat was found dead within one day. A further group of ten rats was therefore dosed at a lower level of 200 mg/kg. Two male rats were found dead within. one day of dosing. A third group of ten rats was then dosed at 80 mg/kg and no mortalities occured. - Clinical signs:
- other: Stage I: Signs of reaction to treatment observed shortly after dosing in all rats were pilo-erection, hunched posture and abnormal gait (waddling). These signs were accompanied by: increased salivation in all rats at 200 and 2000 mg/kg, pallor of extremit
- Gross pathology:
- Stage I:
In the animals that died at 2000 mg/kg bw autopsy revealed congestion or haemorrhage of the lungs and pallor o f the liver, spleen and kidneys. In the surviving animals no abnormalities were observed.
Stage II:
Autopsy of the animals that died revealed congestion of the lungs and pallor of the liver, spleen and kidneys. Pallor of the kidney cortex was also observed in one male rat at 1000 mg/kg. In the surviving animals no abnormalities were observed.
Stage III:
No abnormalities were observed. - Other findings:
- Haematology:
No statistically significant effects were noted.

Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- The LD50 in rats was calculated to be 766 mg/kg bw for males and females combined.
- Executive summary:
An acute oral toxicity study was performed with "Lilamin LS 33". Animals were administered the test substance by oral gavage. The study was divided in three stages. Stage on was a range finding study were rats (2/sex dose) were given a single dose of 2000, 200 or 25 mg/kg bw. Based on these results an up-and-down procedure was followed dosing 1 animal at a time to determine a more exact LD50. In phase III, based on the LD50 findings, 10 animals (5/sex) were given a dose of 80 mg/kg bw and haematological parameters were measured 2 and 7 days after dosing. The LD50 in rats is between 200 and 2000 mg/kg bw, 895 (CI 657-1219) mg/kg bw for males and 637 (CI 467-869) mg/kg bw for females. Based on the performed acute oral toxicity studies the test substance should be classified as harmful (Xn and R22). No effects on haematology were observed after a single oral dose of 80 mg/kg bw.
