Any other information on results incl. tables

Maximum concentration not causing irritating effects in preliminary test: 75 % Signs of irritation during induction: - 1/20 animaux a montré un erythème après l'exposition épidermique. - Application à J7 de laurylsulfate de sodium Evidence of sensitisation of each challenge concentration: 75% : 0/20 (0%) animaux présentant une sensibilisation Other observations: MORTALITÉ: On a trouvé un animal du groupe témoin négatif mort au jour 18 et observé des modifications macroscopiques des poumons. La mort n'est pas liée au traitement.
