Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: Draize
- Principles of method if other than guideline:
- Three male and three female New Zealand White rabbits with 0.5 ml of n-butyl acetate applied to the clipped, intact skin under a gauze patch and loosely covered with impervious sheeting. The animals were restrained for the 4-hour exposure period. Excess liquid was removed at the end of the exposure period. Skin reactions were scored by the Draize method at one hour and 1, 2, 3, 7, 10 and 14 days post-exposure.
- GLP compliance:
- no

- C6H12O2
- IUPAC Name:
- butyl acetate
- Details on test material:
