SCORING SYSTEM:
Scoring and Assessment of Local Reactions:
The dermal irritation scores were evaluated according to the scoring system by Draize (1959). The animals were observed for 72 hours, the duration of the study was sufficient to evaluate fully the reversibility or irreversibility of the effects observed.
Erythema and eschar formation:
No erythema 0
Very slight erythema (barely perceptible) 1
Well defined erythema 2
Moderate to severe erythema 3
Severe erythema (beet redness) to slight eschar
formation (injuries in depth) 4
Maximum possible erythema score: 4
Oedema formation:
No oedema 0
Very slight oedema (barely perceptible) 1
Slight oedema (edges of it will be well defined
by definite raising) 2
Moderate oedema (raised appr. 1 mm) 3
Severe oedema (raised more than 1 mm and extending
beyond area of exp.) 4
Maximum possible oedema score: 4

- Irritant / corrosive response data:
- At observation one hour after patch removal, well defined erythema (score 2) was observed in one animal, very slight erythema (score 1) was found in one animal and very slight oedema (score 1) was found in two animals.
At 24 hours after patch removal, very slight erythema (score 1) was found in one animal and very slight oedema (score 1) was found in two animals.
At 48 and 72 hours after patch removal, there were no observed signs on the skin of the treated animals.
As no clinical signs were observed up to 72 hours after patch removal, the study was terminated after the 72 hour observation.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- According to Directive 2001/59/EC, Vantex T does not require classification as a skin irritant.
According to the UN Globally Harmonised System of Classification and Labelling of Chemicals, Vantex T does not require classification as a skin irritant. - Executive summary:
An acute skin irritation study of the test item Vantex T was performed in New Zealand White rabbits. Parameters monitored during this study included mortality, body weight measurements and clinical observations. The irritation effects of the test item were evaluated according to the Draize method (OECD No.: 404, 2002).
The test item was administered undiluted, at a single dose of 0.5 ml. Gauze was placed onto the hairless skin of the rabbit, test item was applied to the gauze, additional gauze was placed over the test item and an adhesive clear plastic patch applied. The trunk was wrapped in clear plastic with medical tubing used to hold the patch in place. The untreated skin of each animal served as control.
After 4 hours, the remaining test item was removed with water of body temperature.
To assess skin irritation, animals were examined at 1, 24, 48 and 72 hours after the patch removal. Additional general examinations were performed daily.
There was no mortality or systemic clinical changes related to Vantex T administration.
There was no effect of treatment on body weight.
At observation one hour after patch removal, well defined erythema (score 2) was observed in one animal, very slight erythema (score 1) was found in one animal and very slight oedema (score 1) was found in two animals.
At 24 hours after patch removal, very slight erythema (score 1) was found in one animal and very slight oedema (score 1) was found in two animals.
At 48 and 72 hours after patch removal, there were no observed signs on the skin of the treated animals.
As no clinical signs were observed up to 72 hours after patch removal, the study was terminated after the 72 hour observation.
The animals' individual mean scores (considering readings at 24, 48 and 72 hours after patch removal) for erythema were 0.00, 0.00 and 0.33 respectively.
The animals' individual mean scores (considering readings at 24, 48 and 72 hours after patch removal) for oedema were 0.33, 0.33 and 0.00 respectively.
According to Directive 2001/59/EC, Vantex T does not require classification as a skin irritant.
According to the UN Globally Harmonised System of Classification and Labelling of Chemicals, Vantex T does not require classification as a skin irritant.
