 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 

physical/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 

posture, uncoordinated movements, flat gait, shallow respiration, piloerection, 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, perioral 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; paternal 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 Kligman
acute oral study in rats - no deaths at 2000 mg/kg, lethargy, uncoordinated movements, hunched 

posture, chromodacryorrhea

Ecotox Values Comments: Predictions are based on SAR-nearest analog method for alkyl 

anionic surfactants with 6.5 carbons in the linear alkyl hydrophobe; SAR chemical class = 

surfactant-anionic-sulfonamide-ethoxylated (EO1); log Kow of hydrophobe = 3.48 (EPI) which 

is equivalent to 6.5 linear carbons (EPI); MW 360; pH7; effective concentrations based on 

100% active ingredients and mean measured concentrations; hardness <180.0 mg/L as CaCO3; 

and TOC <2.0 mg/L;
