not empty
Administration / exposure
- Route of administration:

- 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 25g/rat/day:
10000 mg/kg diet corresponds with 1000 mg/kg bw/day on average basis:
25 g feed/rat (250g bw)/day = 100 g feed/kg bw/day = 1g active ingredient/kg bw/day = 1000 mg/kg bw/day.

GROSS AND HISTOPATHOLOGY
Following 90 days of feeding, all surviving rats were sacrificed by carbon dioxide asphyxation and autopsied. Animals which died during the study were examined grossly unless examination was precluded by post-mortem autolysis. At the time of gross examination a complete set of organs and other tissues was removed from each rat and preserved in formalin solution. Also at autopsy the weight of the liver and kidneys of ten rats of each sex in every group was determined and recorded.
Microscopic examination of tissues taken from five rats of each sex in every group was conducted. The following tissues, stained with Hematoxylin-Eosin, were included: esophagus, stomach (cardia, fundus and pylorus), small intestine (duodenum, jejunum and ileum), cecum, colon, liver, kidneys, spleen, pancreas, urinary bladder, pituitary gland, adrenal gland, testes, seminal vesicle, ovary, bone marrow, thyroid gland, parathyroid gland, salivary gland, prostate gland, heart, aorta, lung, lymph node (cervical and mesenteric), skeletal muscle, peripheral nerve, bone (femur), spinal cord, uterus, trachea, eye, optic nerve and brain (cerebrum, cerebellum and pons). - Statistics:
- Statistical analyses were conducted upon the absolute organ weights and their corresponding ratios to the weight of the body. An Analysis of Variance was conducted first and any significant effects disclosed by that treatment were further studied by “t” –tests.

Applicant's summary and conclusion
- Conclusions:
- The comparison 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.) - Executive summary:
Five groups of 40 albino rats (20 male, 20 female Charles River Strain) plus 1 control group (20 male, 20 female) were fed with 1% test substance mixed into the diet with various category members of Docusate sodium. After 84 days 5 hematological values, 4 blood chemical values, 5 urinalysis values were measured for all animals. 40 tissues have been examined pathologically at the conclusion of the 90-days test period. Organ to body weight and organ to brain weight ratios were calculated. With the exception of an evaluation of both SGPT (serum glutamic pyruvic transaminase) and SAP (serum alkaline phosphatase) values among males fed CAS 2673-22-5 (Aerosol TR) and smaller absolute liver weights among males fed CAS 127-39-9 (Aerosol IB), no significant differences in clinical blood chemistry studies and absolute organ weights have been detected. 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.
Administration of category members of Docusate sodium at 1% in the diet (10000 ppm equivalent to 750 mg/kg body weight/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.
