LONG - MEDICAL DEPT. - TOXICOLOGY SERVICES - 220-2E Attached please find copies of the reports on the primary skin irritation and eye irritation assessments conducted with your FC-95 (T-1117) by WARF Institute. FC-95 was found to be non-irritating to the skin of albino rabbits under the study conditions utilized. No signs of dermal irritation were observed in any of the test animals at any time during the study period. This product was found to be minimally to mildly irritating to the eyes of albino rabbits under the study conditions utilized. The ocular irritation was limited to that of the conjunctivae in the six test animals at one, twenty-four, and forty-eight hours post-instillation. No conjunctival irritation was observed at the 72 hour examination. No signs of corneal opacity or iridal irri tation were observed in any of the test animals at any time during the study period. Flushing the eyes with plenty of water immediately upon contact should arrest/reverse the irritation pro cess. Precautionary label text should indicate that this product may be irritating to eyes. ; V-JEL :mn v 000026 bcc: H. A. Birnbaum - 220-2E E. J. Deviny - 236-2B G. G. Klaus - 236-3A J. D.

Box 2599 Madison, WI 53701 Dear Dr. Harris: Under separate cover, I am forwarding one 3M sample labeled T-1117 to your laboratory. Please consider this to be a request/authorization for WARF Institute to con duct eye irritation and primary skin irritation assess ments with this sample. In order to assess the eye irritation potential, please instill one-tenth of one gram of test sample into the conjunctival sac of six albino rabbits. Hold the eyelid shut for one second and then examine the test eyes at one, 24, 48, and 72 hours post-instillation and score for ocular irritation according to the procedure of Draize. For the purpose of assessing the primary skin irri tation potential, apply five-tenths of one gram of test sample to intact (dry and wet) and abraded (dry and wet) skin test sites. At 24 and 72 hours post-application, examine the skin test sites and score for dermal irri tation according to the procedure of Draize. Our purchase order for $200 will be forwarded toyyou in the nearffuture. We thank you for your assistance and cooperation in this matter. Sincerely yours, JEL:ran J. E. Long, Sc.D.

They were housed in individual screen bottom cages and fed water and rabbit chow ad libitum. The hair was clipped from the back and flanks of the animal. Five tenths of one gram of test material was placed in intimate contact with the skin on prepared test sites (intact-wet; abraded-wet), and covered with gauze patch and tape to maintain contact with the skin. After a 24 hour contact period, the coverings were removed and the degree of erythema and edema was recorded according to the scale below. Readings were taken again at 72 hours and the 24 and 72 hour readings used to determine the primary skin irritation score.

MAD ISON, W ISCONSIN Sample: T-1117 WARF No. 4102871 Eye Irritation: Method: Adult albino rabbits of the New Zealand White variety were placed in a collar such that the animals could not rub their eyes. Onetenth of a milliliter (0.1 gm for solids) of test substance was instilled in one eye, the other untreated eye served as a control. A series of six albino rabbits was used for each substance. The reaction to the test material was read according to the scale of scoring for damage to the cornea, iris and the bulbar and palpebral conjunctivae at 1, 24, 48 and 72 hours after eye instillation. Any residue of the test material and accumulated discharge are flushed from the eye each time they are scored.
