Any other information on results incl. tables

Maximum concentration not causing irritating effects in preliminary test: 50 %

Signs of irritation during induction:
Du fait de l'absence de signe d'irritation un prétraitement
local au dodécylsulfate de sodium

Evidence of sensitisation of each challenge concentration:
Les effets observés chez les animaux des groupes 2 sont
identiques et sont vraisemblablement de nature irritative.

Les effets observés à 48 h dans le groupe 2 et à 24 et 48h
dans le groupe 3 laissent penser que 3 animaux sur 20 (15%
sont sensibilisés).
