Materials and methods
- Principles of method if other than guideline:
- Adipic acid was tested as a 40% solution in corn oil. Minimum lethal dose was determined using 1-2 rabbits per group (5010 mg/kg bw one animal, 7940 mg/kg bw two animals). A 24- hour dermal exposure under occlusive conditions was conducted. Necropsy was conducted after a 14-day observation period.

Applicant's summary and conclusion
- Executive summary:
No lethality was reported in rabbits following occlusive dermal administration of up to 7940 mg/kg bw of 40 % adipic acid in corn oil for 24 hours. Animals showed reduced appetite and activity and the viscera were normal at necropsy after 14 days observation period (Solutia Inc. 1975).
