- Details on study design:
- RANGE FINDING TESTS: 3 animals topical treated with test item, no signs of irration were recorded after a contact period of 24 h.
- Challenge controls:
- A patch loaded with the test item was applied to the left flank of the animals
and, a patch loaded with Cottonseed Oil to the right flank (intraspecifie control), respectively. The patches were held in contact by an occlusive dressing for 24 hours. At the end of the chaIIenge skin was cleaned with the aid of moistened gauze patches. - Positive control substance(s):
- yes
- Remarks:
- Mercaptobenzothiazole.
Results and discussion
- Positive control results:
- conducted in April/May 1998, concentrations: 2% induction -1 phase, 25% induction-2 phase, 15% in challenge, use of substance as positive control, having mild to moderate sensitizer properties. The study was considered valid.

Applicant's summary and conclusion
- Interpretation of results:
- other: not classified acc. to CLP
- Conclusions:
- Considering the reported data of this sensitization test it can be stated that
the test item AGEE 623 AMIDESTER caused no reactions identified as sensitization.
According to EEC criteria for classification (93/21/EEC) no labelling is necessary
as the sensitization rate was below 30%. - Executive summary:
During the induction phase the guinea pigs (10 test group, 5 control group
all females, strain: Hsd Poc:DH) were intradermally injected with a 20%
suspension of AGEE 623 AMID ESTER and topically treated with 100 %
AGEE 623 AMIDESTER. After a latency of 14 days - to allow a potential
reaction of the immune system - the animals were challenged with the test
item on the flank. The grade of skin reactions was compared to control animals,
which were treated with the vehicle ( cotton seed oil) during the induction
phase and, during challenge phase with the test item, respectively.
The sensitization rate after application of AGEE 623 AMIDESTER was
0 %. Under the test conditions described below the test item showed no sensitizing
properties. No other signs of toxicity were observed. All animals
showed normal food intake and weight gain.
