INTRODUCTION This study was conducted for E.I. duPont <fe Ncmours i Co. to evaluate the dermal corroslvlty produced by 15,615 In rabbits. The study was performed at 810/dynaffllcs, Inc., Mettlers Road, East Millstone, New Jersey 08873. The protocol was based on the following guideline: DOT regulation 173.1300 Appendix A - Method of Testing Corrosion to Skin [46 FR 49889. October 8. 1981. effective July 1. 1982]. This report has been reviewed by the Quality Assurance Unit of Bto/dynamics. Inc. to assure Its conformance with the protocol and raw data. All raw data, the original study protocol and final report will be retained on file In the 81o/dynam1cs Archives. II.

Test Animals: Breed: Albino Rabbits New Zealand White Reason for' Selection: Standard laboratory animal for dermal Irritation studies. The New Zealand White breed was used because of Its availability and because of the existing historical data base for comparative evaluation. Supplier: Hazleton-Dutchland, Inc.

Selection: Animals were randomly placed in cases upon receipt ana were placed on study as available at the time of study Initiation. Animals considered unsuitable for study because of poor health, unacceptable skin, or outlying body weights were excluded from selection. B. Test Material: 15*615 Description: Cloudy, pale yellow liquid Date of Receipt: November 16, 1984 Received from: Storage: E.I. duPont de Nemours & Co. Room temperature V. METHDDS A. Preparation of Test Material: The test material was administered as received; no preparation was necessary. B. Preparation of Animals: On the day before dosing, the hair of each rabbit was closely clipped from the back with an electric clipper, so as to expose the back from the scapular to the lumbar region. The skin remained Intact, I.e.. no abrasions were made. C. Administration of Test Material: There was one test site on the back of each animal. 0.5 ml of the test material was applied to each site beneath a surgical gauze square, T'xl". plac-1 directly on the test site and held In place with tape. Plastic sheeting was then wrapped around the animal and secured with tape to retard evaporation and keep the test substance In contact with the skin without undue pressure. Elizabethan collars were then placed on the animals to prevent disruption of the wrappings and Ingestfon of the test material. Following approximately 4 hours of exposure, the wrappings and gauze squares were removed and the test sites gently wiped free of excess test material with dry gauze. Wo/ /dynmm lac. -4- 5444-84 VI. EXPERIMENTAL EVALUATIO(NIn,-Life) Viability Check: Twice Dally Evaluation of Skin Irritation: 1. Intervals: Approximately 4.5 (30 minutes after removal of wrappings) 24 and 48 hours after administration. 2. Methods: At each Interval alt sites were evaluated for erythema and edema or other evidence of dermal Irritation according to the Draize scoring system (presented In Appendix A). Adjacent areas of untreated skin were used for comparison. iCpmpany Sanitized. Does nol contain TSCA CC B*<^ dynamism Inc. 5444-84 VIII. RESULTS AND DISCUSSION Dermal observations are presented In Table I; the scoring system used is presented In Appendix A. 15,615 was not corrosive. .All animals had very s1<-.,ht (barely perceptible) or well-defined eryjthema with little or no edema at 4.5 and/or 24 hours. This Irritation persisted In some animals through the 48 hour observa tion. No evidence of tissue destruction was seen. ^^wcST^^^^ l'^n^w ^^5^erf^^^._______ Donna ft.LA.T.
