Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 300 - < 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- All female rats dosed at 2000 mg/kg SIKA Hardener LPP (SIKA Härter LPP) died during the study. One animal died on the treatment day 2 hours after the treatment and two animals died 3 hours after the treatment, respectively.
No death occurred at 300 mg/kg single oral dose of the test item. All rats in step 2 and step 3 survived until the end of the 14-day observation period. - Clinical signs:
- In group 1 treated with 2000 mg/kg bw However, red coloured urine was found in all animals on the treatment day between 1 and 2 hours after the treatment. This symptom was not related the test item toxic effect, it was connected with physical property of test item as brownish orange colour. dose clinical sign of reaction comprised of decreased activity (5 cases out of 8 observations), abnormal gait (2/8), decreased righting reflex (2/8), decreased grip- and limb tone (2/8), decreased body tone (2/8), decreased abdominal tone (1/8), decreased plantary reflex (2/8), cyanosis (2/8) and dyspnoea (1/8). Decreased activity (score -3; -4) was observed in all animals. Abnormal gait (score +3, +4), decreased righting reflex (score -4), decreased grip- and limb tone (score -4), decreased body tone (score -3; -4), decreased plantary reflex (score -4) and cyanosis (score +1; +2) occurred in two animals. Decreased abdominal tone (score -4) was found in one animal. Dyspnoea (score +3) was recorded in one animal. These symptoms were observed on the treatment day between 1 and 2 hours after the treatment and they were connected with the test item toxic effect. No systemic toxic symptoms were observed throughout the 14-day post-treatment period in all animals of group 2 and 3 treated with 300 mg/kg bw. Red coloured urine was observed in all animals on the treatment day between 1 and 4 hours after the treatment.
- Body weight:
- The body weight and body weight gain data of group 1 (2000 mg/kg bw) could not be evaluated, because all rats died in this group.
In group 2 and 3 (300 mg/kg bw) the mean body weight of the animals corresponded to their species and age throughout the study. - Gross pathology:
- All rats treated with 2000 mg/kg bw dose of the test item spontaneously died during the study. All animals treated with 300 mg/kg dose of test item survived until the scheduled necropsy on Day 15. Slight hydrometra was found in two females of the group 3. Hydrometra is physiological finding and connected to the cycle of the animal.
No pathological changes were found related to the effect of the test item during the macroscopic examination of animals. - Other findings:
- None
Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- The test item was tested for its acute oral toxicity with rats according to OECD guideline 423. The LD50 was determined to be between 300 mg/kg bw and 2000 mg/kg bw.
- Executive summary:
An acute oral toxicity study was carried out using the class method according to OECD guideline 423. The method was conducted using a stepwise procedure with the use of 2000 mg/kg bw as the starting dose in three female rats. The starting dose was selected on the basis of the available information about the test item. Since three female animals died the test was continued at 300 mg/kg bw dose level on further three female rats. No animal died in the second step at 300 mg/kg bw dose level, three further female rats were treated with the same (300 mg/kg bw) dose.No animal died in the third step, too, so the test was finished, the stopping criteria of Annex 2d of OECD Guideline No. 423 were met.Animals were weighed, observed for lethality and toxic symptoms for 14 days after the treatment. Gross pathological examination was carried out in animals died on the treatment day, as well as 15th day after the treatment in survivor animals.All of three animals treated with 2000 mg/kg bw test item died on the treatment day between 2 and 3 hours after the treatment.No lethality was noted at single oral dose of 300 mg/kg bw. In the first step at a dose level of 2000 mg/kg bw, CNS - and emotion symptom (decreased activity), decreased reflex- and muscular tension (righting- and plantary reflex, body-, abdominal-, grip- and limb tone) and disturbances of the autonomic functions (cyanosis, dyspnoea) and coordination (abnormal gait) were observed in animals on the treatment day between 1 and 2 hours after the treatment. Besides, red coloured urine was detected in animals on the treatment day between 1 and 2 hours after the treatment. This symptom could not be related the test item toxic effect, it was connected with physical property of test item as brownish orange colour. In the second and third step at a dose level of 300 mg/kg bw, red coloured urine was found in animals on the treatment day between 1 and 4 hours after the treatment. The body weight development was normal in all survivor animals. Altogether 3 animals died, and 6 animals were sacrificed scheduled during the study. All organs of all experimental animals proved to be free of treatment related gross pathological changes. The method used is not intended to allow for the calculation of a precise LD50 value.However for this acute oral toxicity study with the test item in rats the determined LD50 is between 300 and 2000 mg/kg bw.
