The toxicity of behenyl alcohol. II. Reproduction studies in rats and rabbits.

PMID 12383720


Behenyl alcohol is a saturated 22-carbon, long-chain aliphatic alcohol, which has potential for use in foods as an oil-structuring and -solidifying agent in fats. Previously completed studies with behenyl alcohol indicated an absence of mutagenic or genotoxic potential. In addition, subchronic toxicity studies in rats and dogs reported no adverse effects following gross and histopathological examinations. Compound-related effects were limited to the observation of pale feces in dogs treated with high doses of behenyl alcohol, and were attributable to unabsorbed behenyl alcohol. The reproductive effects of behenyl alcohol were investigated in a fertility and reproduction study, and an embryonic development study in rats and rabbits, respectively. No evidence of maternal or fetal toxicity was observed in either study. Behenyl alcohol demonstrated no effects on the fertility or reproduction of rats dosed up to 1000 mg/kg body weight. Similarly, behenyl alcohol had no reproductive effects on rabbits treated with doses up to 2000 mg/kg body weight. The observation of pale feces was the only compound-related effect reported, limited to rabbits treated with 2000 mg behenyl alcohol/kg body weight. Based on these findings, there is no evidence to suggest that behenyl alcohol is teratogenic or embryotoxic.
