Any other information on results incl. tables
Maximum concentration not causing irritating effects in preliminary test: 25 %
Signs of irritation during induction:
Die intradermalen Injektionen mit FCA (mit und ohne
Testsubstanz verursachten starke Erytheme und Ödeme, sowie
Verhärtungen und Verkrustungen. Die mit der Testsubstanz im
Vehikel verabreichten Injektionen führten zu leichten
Erythemen und Ödemen. Die Injektionen mit dem Vehikel allein
verursachten keine Reizeffekte.
Die mit FCA behandelten Hautstellen zeigten nach der
dermalen Behandlung klar ausgebildete Erytheme und Ödeme,
sowie Verhärtungen und Verkrustungen und sporadisch
Nekrosen. Die dermale Behandlung mit der Testsubstanz im
Vehikel führte zu leichten Erythemen. Die dermale
Verabreichung des Vehikels allein ergab keine Reizeffekte.
"ENGLISH"
The intradermal injections with FCA (with and without test
substance) caused erythemas and oedemas as well as
indurations and incrustations. The injections administered
with the test substance in the vehicle resulted in slight
erythemas and oedemas. The injections with the vehicle alone
did not induce any irritant effects.
The parts of the skin treated with FCA exhibited clearly
defined erythemas and oedemas as well as indurations and
incrustations and sporadic necroses after the dermal
treatment. The dermal treatment with the test substance in
the vehicle resulted in slight erythemas. The dermal
administration of the vehicle alone did not produce any
irritant effects.
