Administration / exposure

Route of administration:
oral: feed
Vehicle:
unchanged (no vehicle)
Details on oral exposure:
PREPARATION OF DOSING SOLUTIONS: 1.0% in the feed
Taking into account a mean body weight of 250 g and a mean food consumption of 20g/rat/day
(Derelanko M.J., 2008, The Toxicologist's Pocket Handbook, Informa).
1% in the diet = 10000 mg/kg diet corresponds with 10 mg/g diet
20 g feed/rat (250g bw)/day = 80 g feed/kg bw/day = 0.8 g active ingredient/kg bw/day = 800 mg/kg bw/day.
A higher feed intake is possible, e.g. 1000 mg/kg at higher body weight and feed intake, but from a conservative viewpoint 750 mg/kg bw is taken.

Applicant's summary and conclusion

Conclusions:
The comparisons of final body weights and total weight gains revealed no statistically significant differences between test and control animals.
No outstanding differences in food consumption were noted between test rats and control rats.
No deaths or abnormal behavioral reactions were noted among any of the animals employed in the study.
No outstanding differences between test and control rats were noted with respect to any of the blood parameters studied.
(With the exception of an elevation of both SGPT and SAP values among males fed Aerosol TR,) all data obtained from test rats were not different than those from control animals.
No significant differences between the urine of test rats and control rats were observed.
No outstanding differences between test and control rats were noted at the time of gross pathological examination.
The only statistically significant difference noted was smaller absolute liver weights among male rats fed 1.0% Aerosol IB.
There were no significant differences between the tissues of test and control rats observed upon histopathological examination.

Executive summary:

Six groups of 40 albino rats (20 male, 20 female, Charles River strain) plus 1 control group (20 male + 20 female) were fed with 1% of various test items mixed into the diet. The various test items were category members of the Sulfosuccinates Diester Group including Butanedioic acid,sulfo- 1,4 -ditridecyl ester, sodium salt. After 84 days hematological values, blood chemical values and urinalysis values were measured for all animals. Tissues were examined pathologically at the conclusion of the 90-days test period. Organ to body weight and organ to brain weight ratios were calculated. No significant differences in clinical blood chemistry studies and absolute organ weights have been detected, except a slight increase in SGPT (serum glutamic pyruvic transaminase) and SAP (serum alkaline phosphatase). Body weights, organ to body weight ratios, hematologic studies and urinalysis were not different between test and control animals. No deaths or abnormal behavioral reactions occurred; no gross pathological findings were noted. Category members at 1% in the diet (10000 ppm equivalent to 750 mg/kg bw/day) for 90 days in rats did not result in any relevant changes in the subchronic toxicity study. The NOAEL was therefore considered to be 750 mg/kg bw/day.
