Additional information
The following remarks on the toxicokinetics of N,N,N',N'-tetrakis-(2 -hydroxyethyl) hexanediamide are based on physiochemical properties of the compound and on toxicological data. Experimental toxicokinetic studies were not performed.
The test compound has been investigated for acute toxicity by oral and dermal application, for subacute toxicity by oral application and for irritant effects on skin and eyes as well as for skin sensitisation and reproductive toxicity.
In the test for acute and dermal toxicity, the test compound was applied to rats and rabbits at single doses of 5,000 mg/kg body weight. There were no mortalities or body weight effects in any of the studies. Diarrhea, observed 4 hours after oral administration, was the only treatment related clinical sign. Necropsy revealed no gross changes.
In the irritation tests on skin and eyes, only very slight
signs of irritation were seen, which were however clearly
below the threshold for classification and labeling. Signs
of systemic toxicity were not observed.
In a 28-day toxicity study, the test compund formulated as a
solution in distilled water was administered daily to rats
by gavage at dose levels of 10, 100, and 1,000 mg/kg bw/day.
Clearly treatment-related effects with respect to clinical
pathology were not observed. Higher adjusted liver weight
were recorded for rats in the high dose group, being
statistically significant for males only. Significantly
higher adjusted kidney weights were recorded for male and
female rats of the high dose group. In all other respects
including clinical findings and histopathology, treatment
related effects were not observed.
In a one-generation reproduction toxicity study, rats were
administered 1,000, 4,500, and 20,000 ppm (target
concentrations of 50 to 1,000 mg/kg bw/day) test compound in
the diet, beginning at approx. six weeks of age. Animals
were mated after eleven weeks of exposure and treatment
continued throughout gestation, lactation, and until
terminal necropsy. There was no treatment related mortality
observed in any of the groups. Clinical signs were limited
to soft and/or irregular feces observed in male and female
animals exposed to 20,000 ppm. Due to the delayed onset of
this effect (males: after the mating period; females: after
6-7 weeks of treatment), the significance and relation to
treatment is unclear. Reproductive toxicity was not observed
in any of the treatment groups.
No other indications on the toxicokinetix behaviour of the
test compound could be derived from the results of the available studies.
Due to the very good water solubility of 625 g/l and a low
octanol/water partition coefficient of log Kow = -2.45 it
can be assumed that the resorption of the test compound from
the gastrointestinal tract and the skin with subsequent
systemic availability is poor. Exposure to the test compound
by inhalation is highly unlikely due to the low vapour
pressure of 0.0000125 hPa (25 °C).
