- Details on study design:
- The test substance was formulated with water for injection and given only once by oral gavage. Starting dose level was selected 300 mg/kg bw as recommended by the respective guideline. The dose level was 300 mg/kg bw (1st, 2nd step), 2000 mg/kg bw (3rd, 4th step) and 3 animals were used for each step. These steps showed no mortality in the dosed amimals. Clinical signs were observed for 4 hours after treatment and then once every day for 14 days . Body weight was measured on animal recept day , animal allocation day , just before treatment and on day 7 and day 14 after treatment. On the end of study period all animlas were sacrificed and autopsy was conducted to all animals and the organs were examined for gross lesions

Applicant's summary and conclusion
- Executive summary:
The acute oral toxicity was tested in female rats using the acute toxic class method according to OECD TG 423 under GLP conditions. Azo zinc complex Pigment - Melamine compound was formulated with water for injection and given only once by oral gavage. Starting dose level was selected 300 mg/kg bw as recommended by the respective guideline. The dose level was 300 mg/kg bw (1st, 2nd step), 2000 mg/kg bw (3rd, 4th step) and 3 animals were used for each step. No mortality was observed. Clinical signs related with the substance were not observed. All animals gained body weight. There were no necropsy findings. Based on these results
Azo zinc complex Pigment - Melamine compound is evaluated to be of low acute oral toxicity with LD50 > 2000 mg/kg bw
