- Conclusions:
- Under the conditions of this experiment the test material was found to cause moderate irritation when applied to intact and abraded rabbit skin.
In the area of application no discoloration of the skin was observed.
Within 72 hours after starting the application 2 out of 6 rabbits showed necrosis of the skin at the application site. There was a clear tendency of healing during the following observation period.
The calculated primary irritation index was found to be:
