- Details on test animals or test system and environmental conditions:
- The outbred Sprague-Dawley rat, weighing 202 to 283 grams, was used for this study. The animals were obtained from Buckshire Corp., Perkasie, PA 18944 (U.S.D.A. License #23-BL) and were nulliparous and non-pregnant.
The animals were housed and maintained in accordance with standards set forth in the Guide for the Care and Use of Laboratory Animals (NIH Publication No. 86-23). The rats were acclimated to the laboratory for at least 5 days prior to dosing and the weight variation did not exceed +/- 20% of the mean weight for each sex.
The animals were individually identified by an ear punch. Each cage was identified with a cage card, displaying the project number, animal
number, sex, date dosed, dose level and responsible technician's initials.
Temperature: 18°C - 26°C (64.4°F - 78.8°F)
Relative Humidity, %: 40 - 70
Light: 12-hour lightldark cycle
Diet: Wayne Rodent-Blox and tap water were provided gd libitum. Based on our current knowledge, no contaminants are known to be in this diet or water which might be expected to interfere with the objectives of the study.
Caging: Stainless steel elevated wire mesh flooring, 5 ratslcage by sex. - Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- The test article was administered as supplied, at a dose level of 200 mg/kg.
One group of ten (5 male & 5 female) albino rats was deprived of food but not water overnight prior to dosing. Each animal was weighed and dosed by direct administration of the test article into the stomach by gavage.
Following administration, the animals were allowed food and water ad libitum for the 14-day observation period during which time, the rats were observed for signs of toxicity and mortality. Animals were observed frequently on the day of dosing. A careful clinical examination was performed at least once each day (7 dayslweek). On weekdays, a second observation of mortalitylmoribundity was performed.
Individual weights were recorded on the day of dosing, weekly thereafter, and prior to sacrifice. The animals were euthanized using carbon dioxide at the conclusion of the observation period. Gross necropsies were performed on all animals. - Doses:

A group of ten , male, albino rats weighing between 200 and 500 grams each was used in this study, The rats were placed i n a 70 liter all glass exposure chamber and exposed to a saturated atmosphere of the test material in air for one hour, The material was administered
as an aerosol with particles 3 - 5 microns in diameter. The rate of flow was 23,9 liters per minute at a temperature of 76 °F. The air was passed through a dessicant prior to being passed through the test material.
By differential weighing it was calculated that the rats were subjected to a concentration of 19,700 ppm. This is an average value over the one hour exposure period. - GLP compliance:

- Conclusions:
- From the results obtained in this study it appears that Surfynol 61 would be considered non toxic.
The one hour LC50 is greater than 19.7 mg/l. This converts to a four hour LC50 greater than 4.9 mg/l - Executive summary:
From the results obtained in this study it appears that Surfynol 61 would be considered non toxic.
The one hour LC50 is greater than 19.7 mg/l. This converts to a four hour LC50 greater than 4.9 mg/l
Reference
All of the rats survived the one hour exposure period. During the exposure period the rats at first huddled together and their breathing increased in depth. After exposure the rats exhibited complete muscular rigidity with shallow respiration. They remained like this for from one to eight hours and then recovered and were normal throughout the remainder of the observation period. In all rats their eyes appeared normal immediately after removal from the exposure chamber and remained normal throughout the entire observation period. At the end of the 14 day observation period all rats were subjected to gross autopsy examination.
All rats appeared normal on gross examination.

Additional information
Three studies available. The chosen one is the most recent one (1991) is following a guideline (EPA OTS 798.1175), while the other two studies (1971/1972) are less reliable and do not clearly follow a guidline. But both are supporting the result of the selected key study.
Justification for selection of acute toxicity – inhalation endpoint
Only one study available.
Justification for selection of acute toxicity – dermal endpoint
Only one study available.
Justification for classification or non-classification
According to the UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS) Part 3 Chapter 3.1 no classification required for inhalation or dermal toxictiy, for oral toxicity its is considered to be Category 4.
