Applicant's summary and conclusion
- Conclusions:
- The No Observed Adverse Effect Level (NOAEL) for 2-Chloro-p-phenylenediamine SO4 is considered to be 100 mg/kg/day.
- Executive summary:
Combined repeated dose & carcinogenicity study was performed to determine the toxic nature of 2-Chloro-p-phenylenediamine SO4. The study was performed using 6 week old male F344 rats in a 28 days study. The test chemical was mixed with 1% CMC and used at dose level of 0 or 100 mg/Kg/day.Rats were humanly sacrificed with CO2-O2 (4:1) gas inhalation at 3, 14 or 28 days after administration. The livers were immediately excised and weighed. Tissues were fixed in 10% neutral-buffered formalin, and subsequently sectioned and stained with hematoxylin and eosin.No histological abnormalities were noted due to test chemical treatment. The No Observed Adverse Effect Level (NOAEL) for 2-Chloro-p-phenylenediamine SO4 is considered to be 100 mg/kg/day.
