Health : Health Summary: Absorption is nil through the skin as the neat material, moderate through the skin when in solution, and good through the lungs and GI tract based on p hysical/chemical properties. There is concern for lung effects if inhaled and irritation based on the surfactant properties of the PMN material. There is concern for liver and thymus effects and developmental toxicity based on the submitted study for an analog ( N -hydoxyethyl- N -methylperfluorobutanesulfonamide) with a paternal NOEL = 10 mg/kg and a developmental NOEL = 50 mg/kg. Moderate concern. Test Data: P-12-0405:
negative in Salmonella and E coli with and without activation oral absorption/metabolism study in rats - serum half-life is approximately 6 hours (males only) corrosive to the rabbit eye mild skin irritant in rabbits not a dermal sensitizer in guinea pigs, Magnusson and Kligman acute oral study in rats - 2 of 6 died at 2000 mg/kg, lethargy, ventro-lateral recumbency, hunched p osture, uncoordinated movements, flat gait, shallow respiration, p iloerection, salivation
Substance C ( N -hydoxyethyl- N -methylperfluorobutanesulfonamide)
negative for induction of chromosome aberrations in cultured human lymphocytes with and without activation oral combined repeated dose toxicity study with reproduction/developmental screening toxicity test in rats (10, 50, 250 mg/kg) - salivation, p erioral substance and urine-stained abdominal fur at 250 mg/kg; reduced body weight gain and feed consumption at 50 and 250 mg/kg, microscopic changes in liver at 50 and 250 mg/kg; microscopic changes in thymus at 250 mg/kg; no effects on FOB and motor activity; no reproductive effects; reduced number of liveborn pups and increase in stillborn pups at 250 mg/kg; reduced viability of pups and reduced pup weights at 250 mg/kg; p aternal NOEL = 10 mg/kg; developmental NOEL = 50 mg/kg oral absorption/metabolism study in rats (males and females only) - analytic phase of study not completed due to problems with the animals no skin irritation in rabbits oral absorption/metabolism study in rats (male and female) - halflife in serum = 17 hours slight eye irritant in rabbits not a dermal sensitizer in guinea pigs, Magnusson and Kligmanacute oral study in rats - no deaths at 2000 mg/kg, lethargy, uncoordinated movements, hunched p osture, chromodacryorrhea
