Abstract:

Teratogenicity of 2,2,3,3,3-pentafluoro-1-propanol (5FP), an alternative cleaning agent for chlorofluorocarbon, was examined in rats. 5FP was diluted with sesame oil and given to pregnant rats (Crj: Wistar) by gavage once a day from day 7 to 17 of pregnancy at doses of 0, 250, 500 and 1000 mg/kg/day. The pregnant rats were sacrificed on day 20 of pregnancy and their fetuses were examined for malformation. In the pregnant rats, 5FP caused wheezing, salivation, ptosis, reduced body weight gain and reduced food consumption at 500 and 1000 mg/kg/day. In the fetuses, 5FP reduced body weight, increased the incidences of skeletal variations and retarded the ossification at 1000 mg/kg/day, but did not increase the incidences of malformations. It was concluded from these results that 5FP has no teratogenicity in rats when given by gavage. The no-observed-adverse-effect level was 500 mg/kg/day for rat fetuses, and 250 mg/kg/day for pregnant rats.
