Instead of to the back of rabbits test substance was applied to the
inner surface of one ear of each of
2 New Zealand White rabbits and fixed with a plaster for 24 hours.
Afterwards the treatment area was washed with water and soap/plant oil
and was observed for further 7 days . The opposite ear of each of the 2
rabbits served as control. No reaction of the skin was observed. Thus,
Nigrosin WLF has to be evaluated as not irritating to the skin.
