Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the above mentioned findings in an adjuvant sensitization test (M&K-test) in guinea pigs, SALACOS HCISV-L does not have to be treated
as a skin sensitizer. - Executive summary:
In order to assess the cutaneous allergenic potential of SALACOS HCISV-L, the Maximization-Test was performed in 15 (10 test and 5 control) male albino guinea pigs, in accordance with OECD Guideline No. 406 and the Directive 96/54/EEC, 8.6. The intradermal induction of sensitization in the test group was performed in the nuchal region with the undiluted the test item and an emulsion of Freund's Complete Adjuvant (FCA) I physiological saline. The epidermal induction of sensitization was conducted for 48 hours under occlusion with the undiluted test item one week after the intradermal induction. The animals of the control group were intradermally induced with PEG 300 and FCA/physiological saline and epidermally induced with PEG 300 under occlusion. Nineteen days after epidermal induction the control and test animals were challenged by epidermal application of the test item at 1 % in PEG 300 and PEG 300 alone under occlusive dressing. Cutaneous reactions were evaluated at 24 and 48 hours after removal of the dressing.
