Pre-test Evaluation: Evaluated for general health and pregnancy status.
Animals were received from Charles River, Stone Ridge NY on 19 May 2015 and 09 Jun 2015. Following an acclimation period of at least five days, five healthy, non-pregnant and nulliparous female Sprague Dawley rats were selected for dosing without conscious bias. The animals were born the on 23 Mar 2015 or 13 Apr 2015. The pretest body weight range was 195-211 grams. The weight variation of the animals used did not exceed ÷ 20% of the mean weight of the previously dosed animals within a sex. The animals were identified by cage notation and indelible body marks, and individually housed in suspended stainless steel wire bottom cages. Absorbent paper bedding was placed beneath the cages and changed at least three times per week. Fresh PMI Rat Chow (Diet #5012) was freely available except for 16-20 hours prior to dosing. Water was available ad libitcim. The animal room, reserved exclusively for rats on acute tests, was temperature controlled, had a 12-hour lighudark cycle, and was kept clean and vermin free.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- 2000mg/kg bw by syringe and needle orally
- Doses:
- The test article was used as received and the dose was based on the sample weight as calculated from the specific gravity Initially, a single female Sprague Dawley rat was dosed orally by syringe and dosing needle at a dose level of 2000 mg/kg. Since the animal survived, four additional females were dosed at 2000 mg/kg.
- No. of animals per sex per dose:
- 5 female animals
- Control animals:
- no

- Dosing
The test article was used as received and the dose was based on the sample weight as calculated from the specific gravity Initially, a single female Sprague Dawley rat was dosed orally by syringe and dosing needle at a dose level of 2000 mg/kg. Since the animal survived, four additional females were dosed at 2000 mg/kg.
Type and Frequency of Observations
Animals were observed at 15 minutes, 1. 2 and 4 hours postdose and once daily for 14 days for toxicity and pharmacological effects. All animals were observed twice daily for mortality. Body weights were recorded immediately pretest. weekly and at termination.
Post Mortem — All animals were humanely sacrificed using CO2 following study termination and examined for gross pathology.
Analysis of Data
An estimate of the LD50 was made based on the mortality occurring during the study. Analysis was conducted according to the current Globally Harmonized System of Classification and Labeling of Chemicals - Statistics:
- Statistical Analysis: Study data were not analyzed with statistical tests.

Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- Based on the results observed, the oral LD50 of Santicizer P1700 was determined to be greater than 2000 mg/Kg of body weight in rabbits. According to GHS Classification, Santicizer P1700 meets the criteria to be classified as Acute Toxic Category 5.
- Executive summary:
A key EPA Guideline OPPTS 870.1100 / OECD Guideline 425 study was conducted to determine the potential for toxicity of the test material (Santicizer P1700) when administered orally. Five female Sprague-Dawley rats were administered a single dose of Santicizer P1700 (undiluted) via oral gavage at 2000 mg/Kg of body weight. Animals were observed at 15 minutes, 1, 2 and 4 hours post exposure and once daily for 14 days for toxicity and pharmacological effects. All animals were observed twice daily for mortality with body weights recorded immediately pre-test, weekly and at termination. All animals were examined for gross pathology.
No mortality was observed through the study period. No abnormal physical signs were observed among three animals while partially chewed food was observed in the pan liner of two animals. All five animals gained body weight by study termination while one animal lost weight from Day 7 to Day 14 of the study period. Gross necropsy revealed no remarkable findings.
Based on the results observed, the oral LD50 of Santicizer P1700 was determined to be greater than 2000 mg/Kg of body weight in rats. According to GHS Classification, Santicizer P1700 meets the criteria to be classified as Acute Toxic Category 5.
