- Irritant / corrosive response data:
- One hour after patch removal, very slight erythema (score 1) was observed in 3/3 animals. At the 24-hour reading time point 2/3 rabbits showed very slight erythema and 1/3 rabbits well defined erythema (score 2), which persisted in all animals until the 72-hour reading time point. No edema was observed 1 hour after patch removal. From 24 hours until at least 72 hour after patch removal, 1/3 rabbits showed very slight edema (score 1). One animal also showed slight edema at the 72-hour reading time point only, while 1/3 had no edema at any time point. No skin irritation scores were registered after the 72-hour reading time point, but all skin irritation effects were reported to have cleared completely by day 7 of the observation period. For further details see Table 1 under 'Any other information on results incl. tables'.
