Applicant's summary and conclusion
- Conclusions:
- There were no signs of toxicity to reproduction seen in parental animals or offspring in a valid OECD TG 422 oral gavage screening study using rats up to and including 100 mg octylamine hydrochloride/kg bw/day. The NOAEL for reproduction toxicity was therefore 100 mg/kg bw/day.
- Executive summary:
Octylamine-HCl was examined for its potential for repeated toxicity, developmental and neurotoxicity in a combined OECD TG 422 study under GLP conditions. The dose levels used (0, 37.5, 75, an 100/150 mg/kg bw/day; oral gavage; 12 rats/sex/dose) were selected based on the results of two range finding studies, one in the range 100-1000 mg/kg bw/day, and one in the range 3-100 mg/kg bw/day. The high dose group was initially dosed at 150 mg/kg bw/day, but this was lowered 100 mg/kg bw/day by test day 14 because two mortalities were seen in this group. Therefore, this dose level is called “100/150 mg/kg bw/day”. It should however be mentioned that subsequent examinations revealed that these mortalities resulted from maldosing and were not related to the test substance.
The parameters examined in parental animals (gestation length, reproductive function indices [mating index, fertility index, gestation index, implantation efficiency], and corpora lutea counts] and in the offspring (viability at birth and on post partum day 4, sex ratio, weight at birth and on post partum day 4, clinical signs) were comparable across all groups including the control group. The NOAEL for reproduction toxicity was therefore 100 mg/kg bw/day under the conditions of this study.
Overall, there were no signs of toxicity to reproduction seen in parental rats or offspring in a valid OECD TG 422 oral gavage screening study receiving
octylamine hydrochloride up to and including 100 mg/kg bw/day (DuPont, 2007).
