Inductionopen allclose all
- Route:
- intradermal and epicutaneous
- Vehicle:
- physiological saline
- Concentration / amount:
- For the topical applications (induction- second stage and challenge) the test item was applied at a 100% concentration.
For the intradermal injection first stage a 20% concentration was chosen.
Challengeopen allclose all
- Route:
- epicutaneous, occlusive
- Vehicle:
- physiological saline
- Concentration / amount:
- For the topical applications (induction- second stage and challenge) the test item was applied at a 100% concentration.
For the intradermal injection first stage a 20% concentration was chosen.
- No. of animals per dose:
- 10 test animals; 5 control animals per test
- Details on study design:
- RANGE FINDING TESTS: For the justification of dose levels a preliminary test was performed. Three animals were topically treated with the test item. No signs of irritation were recorded after a contact period of 24h. Therefore the maximum concentration was chosen for the topical induction and the challenge.

Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The sensitization rate after application of AGEE 623 Glutaminate 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.
