  2. Classification: Acceptable

Procedural Deviations from ยง152-15: None


Granola 97 was evaluated for dermal sensitization potential using a modified Buehler method. For the induction phase, 0.3 mL of the undiluted test material was applied to the shaved backs of 10 male and 10 female Hartley-derived albino guinea pigs under occlusion for 6 hours once each week for 3 weeks. The animals were left untreated for 2 weeks before challenge. The animals were challenged with 0.3 mL of the undiluted test material under occlusion at naive sites for 6 hours. A naive control group consisting of 5 male and 5 female guinea pigs was treated with 0.3 mL of the undiluted test material at challenge only. Reactions were scored at 24 and 48 hours post exposure.


The test animals demonstrated little (slight, patchy) or no erythema after each induction and challenge dose. The naive control animals also exhibited little or no erythema after the challenge dose. The results of this test were compared to historical positive controls, in which 10 animals/sex were treated with DNCB as a contact sensitizer (all animals exhibited slight-to-moderate, confluent erythema following challenge) within 6 months of the present study. The test substance did not cause contact sensitization under the conditions of this study.
