- Irritant / corrosive response data:
- The erythema in the intact skin areas scored between 1 and 2 (very light and well-defined erythema). These occurred between 1 and 24 hours after removal of the dressing and were detectable up to a maximum of 11 days thereafter. In the abraded regions erythema of strength 1 to 3 (very mild to moderate / severe erythema) occurred. They were detectable beyond the 14-day observation period. From the 6th observation day, there was a formation of scabs in the area of exposure sites. The scabs disappeared after 14 to 22 days, so that the repair process could begin with the irritated skin areas under scarring.
The oedema only had a low intensity (assessment number 1) at the intact skin districts. One animal remained without oedema. These findings were detectable in the intact regions on the fifth day of observation. Oedema of grades 1 and 2 were found in the abraded regions (very light and mild oedema). These findings were also not detectable for more than 5 to 6 days.
Any other information on results incl. tables
The results were assessed against the following index:
0.0 - 0.5 No irritation
0.6 - 3.0 Light irritation
3.1 - 5.0 Moderate irritation
5.1 - 8.0 Strong irritation
The test substance was given a score of 3.17, moderate irritant
Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritant) based on GHS criteria
- Conclusions:
- The report's assesment of the results determined that the test substance was a 'Moderate Irritant'
