Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- According to the results of the study, the registered substance stainless E-700-2003 did not induced toxicity nor mortality in acute dermal toxicity test. Hence, the LD50 was defined as greater than 2000 mg/kg bw (the high dose level used).
- Executive summary:
This GLP-compliant study was performed in order to assess the potential acute toxicity by dermal contact in rats (according to the 402 OECD guideline method).
The test item was dermally tested at 800 and 2000 mg/kg by using 5 males and 5 females HanBrl: WIST (SPF) rats per dose. The test item was diluted in vehicle (purified water) at a concentration of 0.2 and 0.5 mg/ml , respectively administered at a volume dosage of 4 mL/kg. The application period was 24 hours.
The animals were examined daily for mortality, clinical signs and body weight was measured too (day 1, 8 and 15). Necropsy and macroscopic examination were performed at the day 15.
Dose of 800 mg/kg bw : Slight scaling was observed in one female at the 9- and 10-day reading and in one female between day 7 and the end of the study period (day 15). Two females were seen with focal erythema on the test site from the 7-day reading up to the end of the study period. No clinical signs were noted in the females. No clinical signs and no local signs were recorded in the males during the course of the study. Dose of 2000 mg/kg bw : Slight general erythema was observed in four of the females on test day 2 after removal of the dressing. One female still showed a slight erythema on test day 3. Slight focal erythema was seen in two females from test day 7 to the end of the study.No clinical signs were noted in the females. No clinical signs and no local signs were recorded in any of the males during the course of the study, however, a slight yellow discolouration was observed on the skin of all males on day 2 which persisted in four of the animals for at least 3 days.
Loss of bodyweight (0.6% to 4.9%) was observed in one animal of the 800 mg/kg group (female) and in three 2000mg/kg females at the day 8-day reading. By the end of the study, the animal had regained some of weight that was lost. In spite of this body weight loss, the body weight of all animals during the course of the study was within the range commonly recorded for this strain and age
The caecum was distended with gas in one 800 mg/kg treated male at scheduled necropsy. They were no macroscopic in any of the other animals at scheduled necropsy.
According to the results of the study, the registered substance stainless E-700-2003 did not induced toxicity nor mortality in acute dermal toxicity test. Hence, the LD50 was defined as greater than 2000 mg/kg bw (the high dose level used).
