Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- According to Regulation (EC) No 1272/2008, DYNS 2246 does not require classification as a skin irritant.
According to the UN Globally Harmonised System of Classification and Labelling of Chemicals, DYNS 2246 does not require classification as a skin irritant. - Executive summary:
An acute skin irritation study of the test item DYNS 2246 was performed in three 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, as a single dose of , to the hairless skin of all experimental rabbits with moistening by approximately 1 ml of water. 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 DYNS 2246 administration.
There was no effect of treatment on body weight.
At observation one hour after patch removal, very slight erythema (score 1) was observed in all three animals and very slight oedema (score 1) was observed in one animal.
At 24 hours after patch removal, very slight erythema (score 1) was noted in one animal.
At 48 and 72 hours after patch removal, there were no signs observed 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 hours 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 0.00, 0.00 and 0.00 respectively.
According to Directive Regulation (EC) No 1272/2008, DYNS 2246 does not require classification as a skin irritant.
According to the UN Globally Harmonised System of Classification and Labelling of Chemicals, DYNS 2246 does not require classification as a skin irritant.
