Results and discussion
Any other information on results incl. tables
The non-irritant level
was defined as the highest level that no tissue damage and/or
inflammatory reactions were clearly observed.
Non-irritant level (skin):
SnCl4: 5%
SnCl4 + 0.25% SLS: 5%
Non-irritant level (oral mucosa):
SnCl4: 0.05%
SnCl4 + 0.25% SLS: NA*
* - Not available; inconsistent results were obtained.
The test substance (SnCl4) was determined to be an irritant to oral
mucosa at levels >0.05%. The
combination SnCl4 + 0.25% SLS experiments resulted in no evidence of
lymphocytic infiltration. Results
of the combined SnCl4/SLS tests gave results similar to tests where
0.25% SLS was applied to the mucosa 1 minute prior to applying the SnCl4
solution.
In the sensitization tests, no reaction could be determined in animals
sensitized with 3% SnCl4/SLS, followed by oral elicitation with 0.05%
SnCl4.
Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Executive summary:
According to the above presented data form a publication there is no indication of an sensitizing potential.
