PUR POSETo provide information on health hazards likely to arise from a short-term exposure to Vital Oxide by the oral route.2. SUMMARYAn acute oral toxicity test (Up and Down Procedure) was conducted with rats to determine the potential for Vital Oxide to produce toxicity from a single dose via the oral route. Under the conditions of this study, the acute oral LD50 of the test substance is greater than 5,000 mg/kg of body weight in female rats.An initial limit dose of 5,000 mg/kg was administered to one healthy female rat by oral gavage.Due to the absence of mortality in this animal, two additional females received the same dose level, simultaneously. Since these animals survived, no additional animals were tested. Females were selected for the test because they are frequently more sensitive to the toxicity of test compounds than males. All animals were observed for mortality, signs of gross toxicity, and behavioral changes at least once daily for 14 days after dosing. Body weights were recorded p rior to administration and again on Days 7 and 14 (termination) following dosing. Necropsies were performed on all animals at terminal sacrifice.All animals survived, gained body weight, and appeared active and healthy during the study.There were no signs of gross toxicity, adverse pharmacologic effects, or abnormal behavior. No gross abnormalities were noted for any of the animals when necropsied at the conclusion of the 14-day observation period.3. MATE RIALSSubstanceA. TestThe test substance, identified as Vital O xide, Batch #CS062305-1, was received on June 30, 2005 and was further identified with PSL Reference Number 050630-2D. The test substance was a colorless liquid and was stored at room temperature. The sample was administered as received.Documentation of the methods of synthesis, fabrication, or derivation of the test substance is retained by the Sponsor.The following information related to the characterization of the test substance was provided by the Sponsor:Composition: Stabilized chlorine dioxide 0.2% wt.Quaternary ammonium chlorides 0.25% wt.Other ingredients 99.55% wt.pH: Approx. 8.5.Solubility: Soluble in water, methanol, and ethanol.Stability: Test substance was expected to be stable for the duration of testing.Expiration Date: Not applicable.B.

T his number, tog ether w ith a seq uentialanimal number assigned to stu dy number 17854, constitu ted unique identification.5. PRO CE DUR EAnimalsofA. SelectionPrior to each dosing, experimentally naive rats were fasted overnight by removing the feed from their cages. During the fasting period, the rats were examined for health and weighed (initial).Three healthy female rats were selected for test.CalculationsB. DoseIndividual doses were calculated based on the initial body weights, t aking into account the specific gravity (determined by PSL) of the test substance.C. DosingThe test substance was administered using a stainless steel ball-tipped gavage needle attached to an appropriate syringe. Following administration, each animal was returned to its designated cage. Feed was replaced approximately 3-4 hours after dosing.Individual animals were dosed as follows:S – SurvivalD. Body WeightsIndividual body weights of the animals were recorded prior to test substance administration (initial) and again on Days 7 and 14 (termination) following dosing.E. Cage-SideObservationsThe animals were observed for mortality, signs of gross toxicity, and behavioral changes during the first several hours post-dosing and at least once daily thereafter for 14 days after dosing.Observations included gross evaluation of skin and fur, eyes and mucous membranes, respiratory, circulatory, autonomic and central nervous systems, somatomotor activity and behavior pattern.Particular attention was directed to observation of tremors, convulsions, salivation, diarrhea, and coma.F. NecropsAll rats were euthanized via CO2 inhalation at the end of the 14-day observation period. Gross necropsies were performed on all animals. Tissues and organs of the thoracic and abdominal cavities were examined.6. STU DYCO NDUCTThis study was conducted at Product Safety Laboratories, 725 Cranbury Road, East Brunswick, New Jersey 08816.
